Dorumon (ReArise)

Dorumon is Takumi Hiiragi's Partner. Although initially a reluctant ally of the Tamers, Takumi and Dorumon become close friends with the group. They are later forced to turn against the others when Eiji Futami infects Dorumon with a virus, pitting them against the group. They do as Eiji says, as only he could stop the virus, but Takumi eventually decides to find a cure for it himself – turning against Eiji and returning to his friend's side.

Description
When enveloped in a dark aura Dorumon becomes much more powerful and is able to defeat even Champion and Ultimate level Spiral whilst at the Rookie level, however when this happens Dorumon loses control of itself and becomes a threat even to its tamer, Takumi Hiiragi. Due to this, Dorumon doesn't willingly use this ability with it instead activating against its wishes when Dorumon is in life or death situations. Takumi is able to stop these rampages with an unknown item.

Attacks
 * Metal Cannon: Stands still and accumulates power, then fires a more powerful iron sphere from its mouth.

Dorugamon
Dorugamon is Dorumon's Champion form.

When fighting a Spiral Frigimon, Dorumon digivolves to Dorugamon and defeats it.

When the and  get trapped in a Digital Point, Michi Shinjo asks Chihiro Tsukimori for help, and Chihiro sends Dorumon and Takumi. After digivolving to Dorugamon and breaking into the Digital Point, the duo instead find Mayu Kohinata and. Dorugamon and Kudamon then team up to defeat some Spirals, followed by arriving and helping to defeat the rest, saving the Protagonist and. The group are then ambushed by more Spiral, but are able to defeat them, freeing the group from the Digital Point.

When the Truffle Cafe is overcome by a Digital Point, the group of Tamers fight against the Spirals in an attempt to return the cafe back to normal. They split into teams, with Takumi, the Protagonist, and Mayu Kohinata being one group. Mayu wallows in self pity about her usefulness, causing a Wizardmon spiral to attack her, and Dorumon digivolves to Dorugamon and defeats it to protect her. Dourgamon then fights other Spirals alongside the newly digivolved to return the cafe back to normal.

Some time later multiple Digital Points appear all over the City at once, so the group split up to deal with them at once, with Takumi and Dorugamon going to the one in the station, and defeat all the Spirals, turning the park back to normal.

When goes on a rampage in a Digital Point and takes no damage from the attacks of, Dorugamon appears and protects Reppamon by attacking Tyrannomon, after which Dorugamon fights Tyrannomon, whilst Reppamon, , , , and Herissmon fight the Spirals. Even more and more Spirals appear, overwhelming the group. Agumon senses the courage between Herissmon and the Protagonist which causes Agumon to digivolve to, and Dorugamon helps the others clear the path to Tyrannomon so that Greymon can try and talk to it, but it doesn't work as Tyrannomon attacks Greymon as he tries to reason with his friend. After defeating most of the Spirals, the Champion level Digimon help out Greymon, and they come to the conclusion that they will have to kill Tyrannomon to stop its rampage, though Greymon is able to talk them into giving him one more chance to talk to Tyrannomon. As Greymon and Tyrannomon fight, Tyrannomon attempts to digivolve which causes the remaining Spirals to resonate, and their dark energy cause Tyrannomon to dark digivolve to.

During the battle, SkullGreymon defeats Greymon and reverts Greymon back to Agumon. Dorugamon, Reppamon, Gatomon fight back, and eventually, Herissmon digivolves to, which also causes the Spiral to freeze, which allows to join the fight. As the group of Champion level Digimon fight SkullGreymon, Agumon rejoins the fight and then once again digivolves to Greymon, only this time Greymon is able to digivolve a second time, and digivolves to, after which it kills SkullGreymon, which ends the Digital Point. The group then hope they can see Tyrannomon again one day once it's reborn.

When Keito creates an app based on previous Digital Points to help find other Digital Points, it reacts and the group go to the newly found Point, where they find that Takumi and Dorugamon are already fighting the Spiral there. After Elecmon digivolves to Takumi is surprised as he wasn't there when Leomon gained the ability to digivolve to the Ultimate level. Whist fighting, one of the Spiral attacks Filmon, causing Filmon to be unable to move. The Spiral then all group up and attack Filmon, with GrapLeomon and Dorugamon unable to help due to being stuck fighting other Spirals. Filmon's desire to defeat the Spirals to protect his friends causes him to lose control and go berserk, and its rage causes him to defeat the Spirals that were attacking him. A SkullMeramon type Spiral than spawns and attacks him, and Filmon's desire to protect its friends causes him to digivolve to. Filmon's digivolution to Ultimate causes Takumi to get even more jealous. Stefilmon easily defeats the SkullMeramon Spiral, however this doesn't calm Stefilmon down who then proceeds to attack his friends during his rampage. As Stefilmon fights GrapLeomon, Dorugamon, and, the group realise that the Spiral must've done something to Stefilmon, and Takumi states that they may have to kill Stefilmon if he continues to rampage. After the group defeat all the Spiral, the Digital Point disperses and Stefilmon, still rampaging, reverts back to Herissmon and passes out from exhaustion.

Takumi and Dorugamon spend an entire day fighting Spirals in various Digital Points, exhausting both of them. Takumi however refuses to let Dorugamon rest. Eventually they find themselves in the same Digital Point as Herrismon, the Protagonist, Keito, Elecmon, Michi, and Salamon, and when Salamon was about to digivolve to Gatomon to fight a Starmon type Spiral, Takumi and Dorugamon interfere and try to defeat the Spiral instead, although Elecmon defeats it before Dorugamon can. Seeing the rough shape Takumi and Dorugamon are in the rest of the group are worried and tell them to rest, but Takumi states that there is no time do so. The Digital Point expands, and Takumi claims that Dorugamon can deal with it on its own. Whilst Dorugamon fights the Spiral, Leomon digivolves to GrapLeomon and protects Dorugamon, which makes Takumi jealous due to GrapLeomon being more powerful than Dorugamon, so he ditches the others, still wanting Dorugamon to defeat all of the Spirals on its own. They find a group of Tankmon fighting Starmon and SkullGreymon type Spiral, however the Spiral do something to the Tankmon, which causes them to go on a rampage and so Takumi tells Dorugamon to not only defeat the Spirals, but the Tankmon as well. Dorugamon is no match for them however and is defeated, so GrapLeomon once again comes in to save Dorugamon, knocking away most of them to protect its friend. As Dorugamon laments that it is unable to digivolve to Ultimate, Takumi tells Dorugamon that it is the strongest Digimon which gives Dorugamon the spirit to fight again and causes Dorugamon to finally be able to digivolve to Ultimate.

When it snows, the group all have a snowball fight, however in the middle of it Herissmon is suddenly enveloped in a dark aura and wanders off. After the group follow Herissmon they discover he had lead them to a Digital Point, in which Frigimon-type Spiral were attacking a Wanyamon and a Motimon. The Spiral split the Digital Point in two, causing the group to split up, and Elecmon, Dorumon, and Salamon digivolve to Leomon, Dorugamon, and Gatomon to fight the Spiral in an attempt to reunite with their friends.

When Takumi and Dorumon reconcile, with Dorumon having ended their partnership due to no longer wanting to be evil – Takumi decides to stop working for Eiji Futami, who had infected Dorumon with a virus and forced Takumi to work for him to cure his partner. Dorumon quickly digivolves multiple times back to back, having gained access to a new form, – with it spending a short amount of time during the battle against the Spiral Eiji summoned as Dorugamon.

When the Tamers break into the Kernel, they are ambushed by a group of weak Spiral leading them to all digivolve to the Champion level to defeat them.

Attacks
 * Power Metal: Stands still and accumulates power, then fires a large, more powerful iron sphere from its mouth.
 * Cannonball: Fires a large iron sphere from its mouth while charging.

DoruGreymon
DoruGreymon is Dorumon's Ultimate form.

After Dorugamon is defeated by a group of SkullGreymon and Starmon type Spiral, alongside a group of Tankmon that had gone on a rampage due to the Spirals influence, comes to Dorugamons aide and knocks the enemies aside. Jealous of GrapLeomon's Ulitmate level power, Takumi tells Dorugamon that it is the strongest Digimon and this gives Dorugamon the will to carry on fighting. Spurred on by its bond with Takumi, Dorugamon digivolves to DoruGreymon and attacks and defeats the Spiral, with the Tankmon getting hurt in the attack, though the defeat of the Spiral returns them to their normal states. DoruGreymon attacking the Tankmon upset the rest of the group, though Takumi and DoruGreymon don't care as they were able to defeat the Spiral, protecting everyone. DoruGreymon then states that it will deal with if it ever goes on a rampage again with its new found powers and leaves alongside Takumi.

After the group are split up due to a group of Frigimon-type Spiral splitting the Digital Point in two, Leomon, Gatomon, and Dorugamon try to attack the barrier preventing them from reaching The Protagonist, Herissmon, Mayu, and Kudamon, however they find that Champion level attacks hav no effect on the barrier, so Leomon and Dorugamon digivolve to GrapLeomon and DoruGreymon. After repeatedly attacking the barrier they are able to break through and reunite with the rest of the group. Takumi then realises that they cannot win fights with power alone.

Takumi and DoruGreymon spend the next two months using Keito's app to track Digital Points, clearing them of Spirals. After clearing three in one day DoruGreymon requests a break, though Takumi refuses and tells DoruGreymon to continue, which pisses of DoruGreymon. As they find another Digital Point, they find it unusual that there are no Spiral around and after coming across a group of SkullMeramon and a Chaosdramon arguing, DoruGreymon realises that the Spiral were gathering Digimon. Eventually the Chaosdramon kills the SkullMeramon and DoruGreymon and Takumi are surprised at how easily it managed to kill the Ultimate level Digimon, though still decide to fight it and agree to "tap out" if the fight gets too hard. DoruGreymon ambushes the Chaosdramon, however its attacks do nothing and DoruGreymon is easily defeated, so Takumi and DoruGreymon run away as DoruGreymon de-digivolves back to Dorumon.

They round up the rest of the tamers and the group return to the Digital Point. Dorumon warp digivolves to DoruGreymon, and alongside the rest of the Digimon, fight the Spiral that spawn, coming to the conclusion that they didn't show up last time as they were hiding from Chaosdramon. After defeating all the Spiral they find Chaosdramon, and DoruGreymon attacks Chaosdramon on its own, however its attacks once again do nothing though this time DoruGreymon is able to withstand Chaosdramon's attack. As Chaosdramon readies its second attack Filmon runs in the way of it to protect DoruGreymon and after taking the blow is overcome by a dark aura, demanding more power so that it can protect Takumi and DoruGreymon. Filmon digivolves to Stefilmon, followed by Chirinmon and GrapLeomon teaming with Stefilmon - which pisses off Takumi as he prefers to be taken out by the Chaosdramon on his own. Mayu and Michi lecture Takumi, telling him that he isn't on his own and that his friends are here to help him and Takumi eventually realises that they're right, and that he was being too arrogant - always thinking he could do everything on his own. He decides to actually work together with the rest of the group and this new found resolve from Takumi causes DoruGreymon to digivolve to .

When Herissmon runs away due to the Spirals telling it to kill all of its friends the group split up and Takumi and Dorumon find Herissmon in a nearby Digital Point. Once they arrive a group of Spiral spawn and Dorumon warp digivolves to DoruGreymon to destroy them. As Herissmon leaves, even more spawn in an attempt to stop the duo reaching Herissmon and so they decide they will have to stop the Digital Point to be able to help Herrismon.

When Takumi and Dorumon reconcile, with Dorumon having ended their partnership due to no longer wanting to be evil – Takumi decides to stop working for Eiji Futami, who had infected Dorumon with a virus and forced Takumi to work for him to cure his partner. Dorumon quickly digivolves multiple times back to back, having gained access to a new form, – with it spending a short amount of time during the battle against the Spiral Eiji summoned as DoruGreymon.

When the Tamers break into the Kernel, they are ambushed by a group of weak Spiral leading them to all digivolve to the Champion level to defeat them. They continue to transverse the Kernel and are attacked by stronger Spiral, so digivolve once again to the Ultimate level to deal with them. Even more powerful Spiral show up though, so they once again digivolve – this time to the Mega level (with the exception of ).

Attacks
 * Bloody Tower: Skewers the opponent before flinging them up into the sky.
 * Metal Meteor: Fires a supermassive iron sphere more than ten times its own size, crushing the opponent in one hit.

Gaiomon
Gaiomon is Dorumon's Mega form.

After runs in the way of an attack from a Chaosdramon to protect DoruGreymon, Filmon digivolves to  so that it can protect Takumi and DoruGreymon. As Stefilmon fights the Chaosdramon, and  join it in battle, which pisses off Takumi as he prefers to be taken out by the Chaosdramon on his own. Mayu and Michi lecture Takumi, telling him that he isn't on his own and that his friends are here to help him and Takumi eventually realises that they're right, and that he was being too arrogant - always thinking he could do everything on his own. He decides to actually work together with the rest of the group and this new found resolve from Takumi causes DoruGreymon to digivolve to Gaiomon. Feeling its bond with the rest of the group, Gaiomon overpowers Chaosdramon and states that Chaosdramon cannot win against the group, and so Chaosdramon decides to attack the Tamers in attempt to lower their numbers though Gaiomon finishes off Chaosdramon before it is able to kill the Tamers. As Chaosdramon dies, it swears it will return to get its revenge against the group one day.

When Herissmon runs away due to the Spirals telling it to kill all of its friends the group eventually find it, having been forced to digivolve to Stefilmon by the Spiral, where the Protagonist and Herissmon first met. The Spiral trick it into thinking that the Protagonist had replaced it as its partner with and the shock of this causes Stefilmon to become depressed, which allows the Spiral to take control and force Stefilmon to go on a rampage and so Dorumon warp digivolves to Gaiomon in order to fight Stefilmon and the nearby Spiral that were controlling it. As the group fight Stefilmon and the Spiral, the Spiral fuse with Stefilmon, force it to digivolve to, and then force it to leave the Digital Point in an attempt to destroy the City.

As Rasenmon Fury Mode attacks passersby the group realise they can't fight in the City due to buildings and the nearby people and so try to evacuate the City and find a more safe place to fight. Chirinmon attempts to leave to help evacuate the citizens, however Takumi points out that Gaiomon is faster and so would be able to do it quicker and so leaves to do so. As the rest of the group distract Rasenmon, Gaiomon is able to help evacuate everyone from the City. The group then continue to fight Rasenmon, only for a Digital Point to suddenly open up, after which a group of Spiral spawn, leading to group to fight not only Rasenmon but the Spiral as well. As Gaiomon fights countless Spiral,, , and Chihiro Tsukimori arrive and take Gaiomon's place in fighting the Spiral so that Gaiomon could focus on fighting Rasenmon.

The group continue to fight Fury Mode but just as it starts to slow down it absorbs some of the nearby Spiral which re-energises it, restoring it back to full power. As the fight continues, Fury Mode and the remaining Spiral suddenly turn into fragments as Herissmon had awakened inside Fury Mode, digivolved to, and got its message across that the Spiral and Herissmon were the same and that there was more to the World than just sadness and despair. The fragments then form into Pusumon's Digi-Egg.

Months later when was fighting the two,  and , in a Digital Point, as the Deva assumed the Humans were behind the constant Spiral attacks in the Digital World, they acknowledge that Chirinmon is strong. Just as the fighting ceases charges into the battle and defeats the two Deva. Assuming that Machinedramon was on a rampage digivolves to  and attacks Machinedramon, though Gaiomon suddenly arrives and intercepts the attack. As Takumi arrives Kazuma Natsuyagi runs up to him, reuniting with the friend he had been searching for. angrily yells at Kazuma for putting into danger by running up to the enemy in the middle of battle. Wanyamon chases after Kazuma, stating it will protect him and digivolves to though Takumi has Gaiomon fight SaviorHuckmon instead of Bearmon. Takumi, deciding that he needs to press "them" for answers, moves onto the next location though is chased by SaviorHuckmon and Bearmon. As the fight continues Takumi is sent a message, which causes him to have Gaiomon retreat from the battle. SaviorHuckmon and Mon attempt to chase the duo though Gaiomon aims an attack at Mon - which SaviorHuckmon blocks - the distraction giving Takumi and Gaiomon enough time to escape.

Having learned that the had given their  subordinates their DigiCores Takumi and Gaiomon track down  and try to force it to give them one of the DigiCores, which Sinduramon refuses. Takumi and Gaiomon resort to beating up Sinduramon and just as it's about to kill the Deva, Bearmon and Kazuma charge in to try and protect it though are unable to do anything due to Gaiomon being a Mega – and digivolving to fails to change the tide of the battle. Just as Gaiomon is about to kill them SaviorHuckmon arrives and saves Grizzlymon from Gaiomon though it tells the entire group to retreat when Gaiomon charges up an attack intended to blow up the area as Takumi no longer cared what happened to anyone as he had managed to retrieve the DigiCore from the defeated Sinduramon, with the group escaping death just in time.

When is about to defeat Machinedramon in a Digital Point after Sara confirms to everyone else that she is behind all the problems in the Digital World, Gaiomon suddenly arrives and attacks Leopardmon. Gaiomon uses itself as a distraction and fights Leopardmon so that Machinedramon can escape whilst Sara spawns a group of Spiral to distract everyone else. Just as Machinedramon is about to fire a surprise attack it stands on an Eroberung energy mine that Leopardmon had set up earlier in the fight. Despite taking large amounts of damage Machinedramon is still able to battle and continues to team up with Gaiomon, firing off a combined attack. Leopardmon realises it is about to be defeated by the two Digimon, only for Jesmon to arrive and block the attack. Sara and Takumi realise they wouldn't be able to take out two Royal Knights and escape through the gate to the Dark Area. This pisses Leopardmon off, having underestimated its opponents, and it leaves after apologising to the other Tamers for fighting them.

When travels the City drinking various human's blood it one day runs into Sara and Tapirmon, though Matadormon escapes stating this wasn't the right time for them to meet. She tells Takumi about this who decides to search for Matadormon and eventually finds it one night about to attack Chihiro Tsukimori. Gaiomon attacks Matadormon and saves Chihiro. It fights Matadormon, though Matadormon's attack do very little damage – which annoys it as it realises it stands no chance against a Mega whilst stuck at the Ultimate level. Realising it needs to escape it fires an attack at Chihiro and escapes as Gaiomon blocks the attack.

Despite pretending he didn't care about the coma case, Takumi eventually decides to help deal with it against the wishes of Eiji Futami, though he allows him to do so provided he doesn't get in the way of its plan. When Takumi tries to contact the others he is attacked by a VenomMyotismon sent by, causing Gaiomon to fight it. After defeating it they see Sara and Tapirmon go through the portal to the Dark Area but are too late to stop them.

Sometime later, Gaiomon and Machinedramon fought of the Royal Knights though they ran away due to Crusadermon overpowering them even with the two on one advantage. The Digimon and their Tamers get split up in the ensuing fleeing, and whilst trying to find Sara and Machinedramon they are stopped in their tracks by a group of Knightmon sent by Crusadermon. Gaiomon is able to kill most of them though reverts to Dorumon due to not having enough energy to kill all of them and ends up getting separated from its partner.

When Takumi and Sara are discussing their plan to ambush the summit between the, , and they are attacked by a group of Spiral, leading Dorumon to warp digivolve to Gaiomon to defeat them alongside Machinedramon, which also allows Sara to add to her collect of Spiral. As the summit was on break, with each group split up during said break by the time Sara and Takumi show up, they are only able to find the Archangels. Machinedramon and Gaiomon attack them though during the fight the Protagonist, Rasenmon, Michi, and LovelyAngemon arrive, confused as to why they were fighting. The Tamers join the fight to stop them, though Sara summons a group of Spiral which are able to stall the group long enough for Sara and Takumi to complete their goal, after which they flee through a portal.

Some time later, whilst still in the Dark Area, Dorumon questions Takumi on his recent evil actions with Takumi merely saying that they had to do them without offering explaination. Just as Dorumon yells that it will just stop being Takumi's partner, as it doesn't like being evil, and  arrive through the nearby portal and attack Takumi which causes Dorumon to warp digivolve to Gaiomon to protect him. As Takumi fights, he realises they can't win – and has Gaiomon flee. As they run away, they try to trick Seraphimon into falling into their nearby trap, whilst Seraphimon charges up an attack that would kill everyone. As Takumi refuses to give up, still wanting to defeat the Archangel, Gaiomon surrenders – finally standing up to Takumi, refusing to be evil and blaming itself as it realised that Takumi would never do something evil unless it was to protect his partner. Gaiomon then ends its partnership with Takumi and dedigivolves to Dorumon. Seraphimon accepts the surrender, however Sandiramon does not and attacks the duo – once again with the intent to kill them. After attacking Takumi and knocking him unconcious Sandiramon attempts to kill Dorumon though the other Tamers arrive and protect their former allies. As it fights against them, a group of Spiral, summoned by Eiji Futami, show up and using the power hacked into them by Eiji, paralyses everyone. When Takumi awakens and learns of this he realises that that means Dorumon was paralysed as well and, despite the great pain he was in, charges in to try and protect Dorumon. Takumi finds Dorumon on the verge of death and admits he had done all the evil things to protect it (with Eiji having put a virus inside Dorumon, forcing Takumi to do his bidding to cure him) and would still do it all over again, despite knowing that he was doing wrong as he just wanted to protect his partner. The two reconcile and come to understand each other, with Takumi deciding that he will stop working for Eiji and instead cure Dorumon's virus on his own. With their partnership renewed and the duo back on the side of good, Dorumon quickly digivolves multiple times and eventually becomes Gaiomon again. Now reformed, Gaiomon gains access to a new form and digivolves to

Attacks
 * Will-O'-Wisp Slash (燐火斬): Uses its Kikurin swords to leave behind eerie tracks of light which cut anything that comes in contact with them to pieces.
 *  Reactor: Concentrates all the energy within the atmosphere, and then detonates it.
 * Rinkageki (燐火撃): Fuses the two Kikurin swords, which causes the eerie tracks of light to converge all at once, allowing it to attack distant enemies.

Gaiomon Fierce Blade Mode
Gaiomon Fierce Blade Mode is the digivolved from of.

When trying to achieve their goal to trap for Eiji Futami, who had forced Takumi to work for him after infecting Dorumon with a virus, they realise they cannot defeat the Angel and flee. As they run away, they try to trick Seraphimon into falling into their nearby trap, whilst Seraphimon charges up an attack that would kill everyone. As Takumi refuses to give up, still wanting to defeat the Archangel, Gaiomon surrenders – finally standing up to Takumi, refusing to be evil and blaming itself as it realised that Takumi would never do something evil unless it was to protect his partner. Gaiomon then ends its partnership with Takumi and dedigivolves to Dorumon. Seraphimon accepts the surrender, however does not and attacks the duo – once again with the intent to kill them. After attacking Takumi and knocking him unconcious Sandiramon attempts to kill Dorumon though the other Tamers arrive and protect their former allies. As it fights against them, a group of Spiral, summoned by Eiji, show up and using the power hacked into them by Eiji, paralyses everyone. When Takumi awakens and learns of this he realises that that means Dorumon was paralysed as well and, despite the great pain he was in, charges in to try and protect Dorumon. Takumi finds Dorumon on the verge of death and admits he had done all the evil things to protect it and would still do it all over again, despite knowing that he was doing wrong as he just wanted to protect his partner. The two reconcile and come to understand each other, with Takumi deciding that he will stop working for Eiji and instead cure Dorumon's virus on his own. With their partnership renewed and the duo back on the side of good, Dorumon quickly digivolves multiple times and eventually becomes Gaiomon again. Now reformed, Gaiomon digivolves to Gaiomon Fierce Blade Mode, defeats the Spirals, saves everyone's lives, then uses its new powers to remove everyone's paralysis. Rasenmon then opens up another portal, taking everyone back to the Human World. Takumi tells the group that Eiji was evil, so they decide to confront him. The group are able to find him and, finding him with Sara and Machinedramon – who are in the middle of fighting, LovelyAngemon, and Mitamamon – join the battle. The group fail to stop Eiji however as he is able to have Machinedramon and the Spiral stall them long enough to be able to run through the gateway to the Kernel. Unfortunately for Eiji, the gateway remained open due to Cherubimon using its remaining power with the Tamers being able to get Rasenmon, Jesmon, and their Tamers through the gateway as well before Cherubimon passes out.

Despite this failure, Sara and Machinedramon refuse to back down – deciding that although they failed to stop some of them getting to the Kernel, they could still kill the others to stop them ever being a threat again. Sara summons a large group of Spiral, which then fight the remaining Partner Digimon alongside Machinedramon with Machinedramon using its powerful mind to have them do its bidding. As the battle continues, Sara summons more Spiral to replace the destroyed Spiral and eventually Keito notices that the high amount of Spiral activity was causing the Digital Point to glitch out. He orders the group to retreat, though when Michi notices that Sara wasn't retreating she runs to her to try and tell her what was about to happen coming to the conclusion that she had no idea what happens when too many Spiral access a Digital Point. As the rest see Michi charge at Sara they stop retreating trying to stop her but it ends up being too late, with the Digital Point transporting everyone to the Digital World. This also de-digivolved everyone back down to the Rookie level.

When the Digital World falls into disarray after Eiji breaks into the Kernel, a large group of evil Digimon and Spiral cause havoc in the Digital World and so it, Takumi, Kazuma, and Grizzlymon travel the Digital World to defeat them and protect the weaker Digimon. On one such trip the other Tamers, alongside Sara and Eiji, teleport in front of them and inform them about how Sara had returned to their side and Eiji had been betrayed by Spiral Origin, with them using gates made by Herissmon/Eiji to get back into the Kernel with the gates first sending them to the other Tamers as Herrismon had unintentionally caused the gates to do so due to wanting to reunite with all the other Tamers. With Takumi/Kazuma being the last of them, they go through another gate though rather than the Kernel it sends them to the Dark Area – with them being dropped right in front of GranDracmon. GranDracmon is delighted that its beloved Tamers had appeared before it though with it not yet being strong enough to defeat them it survives their combined attack, uses Eye of the Gorgon on Herissmon, and is able to brainwash Herissmon and cause it to warp digivolve to once again. Before it can do anything however, the Protagonist is able to snap it out of it and revert it back to Herissmon simply by calling out to it which annoys GranDracmon. It manifests a copy of Rasenmon Fury Mode and has it attack the group, though Herrismon warp digivolves to Rasenmon and is able to defeat the copy. Defeated, GranDracmon retreats. Rasenmon is then finally able to open a gate to the Kernel, though Spiral Origin sends the Spiral Guardians (G-Spiral-6097, G-Spiral-6098, and G-Spiral-6099) through it from the other side to attack them.

As the group struggle against the Spiral Guardians they realize that they need more help to be able to defeat them. Grizzlymon, wanting to be more useful to the group as it couldn't do much whilst still stuck at the Champion level, forces itself to digivolve to so that it could open a gate to the Dark Area so that more of their allies can join the battle. No one appears to come out of it though, which leads Spiral Origin to boast that it had used the Kernel's power to delete the Digital World, and assumes it had worked. It taunts the Tamers about the fact they had failed and that everyone was dead only for to tell it to shut up, which caused the group to realize they had indeed summoned at least one ally to help them. Spiral Origin freaks out, as it should've been dead alongside the Digital World, with Sandiramon telling them that the Digital World still existed as the Four Holy Beasts had managed to stop the deletion at the last second. Sandiramon then allows Cerberusmon to use the DigiCore it had been entrusted with by the Four Holy Beasts to be used to open multiple gates at once which allows all members of the Deva, Royal Knights, and Three Archangels to join the battle. With the group now being much bigger, their combined forces are able to defeat the Spiral Guardians. Spiral Origin revives them however, though the large group of newly summoned allies fight them and allow the Tamers to go to the Kernel.

In order to break into the Kernel the Digimon had to dedigivolve back to the Rookie level. Upon geting into it, they are ambushed by a group of weak Spiral leading them to all digivolve to the Champion level to defeat them. They continue to transverse the Kernel and are attacked by stronger Spiral, so digivolve once again to the Ultimate level to deal with them. Even more powerful Spiral show up though, so they once again digivolve – this time to the Mega level (with the exception of Cerberusmon, as it is unable to digivolve to Mega. DoruGreymon also skips Gaiomon, and digivolves directly to Gaiomon Fierce Blade Mode). Origin spawns even more Spiral, with everyone except Rasenmon fighting them. Rasenmon tries to talk Origin down and as it does, it is given power by rebellious Spiral who didn't want Origin to destroy the World and instead wanted to be friends with everyone (as Origin was unable to exert its will over the entire Hive Mind at that point). Origin uses the ones it still had control over to become its own unique form, though the rebellious Spiral power up Rasenmon up enough to allow it to defeat Spiral Origin. This also causes all the other Spiral disperse as well.

Months later, Dorumon warp digivolves to Gaiomon Fierce Blade Mode to fight.

At some point, with the duo now back on the side of good, Gaiomon Fierce Blade Mode sparred with in the Digital World as Rasenmon wanted to do so, having already sparred with all the other Megas. They battle for a long time, eventually ending with a draw after both run out of energy and dedigivolve at the same time.
