The Spirals freezing allows to join the fight, and the Champion level Digimon fight against SkullGreymon. Agumon then re-joins the fight, digivolves to, and kills SkullGreymon, after which the Digital Point ends. The group then hope they can meet Tyrannomon once again when it's reborn.

When the Herissmon, the Protagonist, Chihiro Tsukimori, and are searching for, they find that Terriermon had been fighting the Solarmon type Spiral for fun. This angered the Spiral, which causes them to fuse together into a Tankmon type Spiral, which proves to be too much for Lopmon and Terriermon. Herissmon digivolves to Filmon, and with the help of Lopmon, defeats the Spiral, returning the Digital Point back to normal.

When Herissmon, the Protagonist, Keito Tamada,, Michi Shinjo, and go to the park where Nozomi Tamada and  were playing when a Digital Point opened up, Herissmon digivolves to Filmon to help fight the Spiral alongside Pumpkinmon, , and. The Digital Point is eventually stopped by.

When Keito creates an app based on previous Digital Points to help find other Digital Points, it reacts having found a new Digital Point. The Protagonist, Herissmon, Elecmon, and Keito go to the newly found Digital Point, where they find that Takumi and Dorugamon are already fighting the Spiral. As more spawn, Elecmon and Herissmon decide to digivolve to Champion so that they could match the power of the Clockmon type Spiral. Whist fighting, one of the Spiral attacks him, 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 protects 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.

When Leomon digivolves to GrapLeomon after a Digital Point expands, causing more powerful Spiral to spawn, Herissmon tries to digivolve to Filmon, though the Protagonist and Keito stop Herissmon from digivolving, worried that Herissmon would go on a rampage again.

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 and cause the group to be split up, and Herissmon's rage at seeing the In-Training Digimon being attacked causes him to defeat the Spiral, but in the process he harms the In-Training Digimon as well. As more Spiral spawn, Herissmon and Kudamon digivolve to Filmon and Reppamon to fight them. As Filmon fights the endless stream of Spiral, he gives into the rage more and more and when the rest of the group are able to reunite, Filmon attacks Gatomon under the impression that Gatomon was an enemy. As Filmon realises that he attacked Gatomon, the group are surrounded by SkullGreymon-type Spiral and when Reppamon begins to struggle against the remaining Frigimon Spiral, Mayu charges in and tries to help and is attacked - and Filmon, now back to his senses, saves Mayu's life, after which Mayu asks Filmon to support Reppamon in fighting the rest of the Spiral. Filmon and Mayu arrive just in time to save Reppamon's life and Reppamon is surprised to see Mayu risking her life to save it, and digivolves to through the power of their stronger bond. Filmon then digivolves to Stefilmon to help Chirinmon fight the Spiral.

After DoruGreymon is easily defeated by a Chaosdramon in a Digital Point, Takumi asks the group for help and they return to the Digital Point together so they can fight the Chaosdramon and stop it before it attacks the Town. Herissmon digivolves to Filmon, rather than Stefilmon, as they worried about what would happen should Herrismon digivolve to Stefilmon. Filmon fights the Spiral there with the rest of the group and 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 next attack, Filmon runs in front of it to protect DoruGreymon and after taking the attack, Filmon is overcome by a dark aura and demands more power so that it can protect Takumi and DoruGreymon and despite the protests of the rest of the group, digivolves to Stefilmon.

Worried about the fact that Herissmon would frequently wander off on its own and not remember doing so, the group come to the conclusion that Herissmon's ability to detect Spiral may be the reason and so decide to defeat all the nearby Spiral in the hope it would help Herissmon. Herissmon digivolves to Filmon and teams up with Gatomon, Leomon, and Reppamon to cleanse the nearby Digital Points - however as they continue to clear them out Filmon is surprised attacked by a SkullMeramon Spiral which causes a Digital Point to open up around Filmon, forcing it to digivolve to Stefilmon.

Some time later Herissmon is still being controlled by the Spiral, and they tell it to kill all of its friends and so Herissmon runs away not wanting to do this. As it evades its friends it is found by Nozomi Tamada and and the Spiral tell it to kill them. Herissmon refuses and so the Sprial force it to digivolve to Filmon, though Filmon still has enough control to be able to leave, instead of attacking Pumpkinmon, muttering that it's not unneeded as it leaves the park. As it wanders around the City, it finds itself in various Digital Points however the Spiral keep spawning which makes it so that its friends are unable to find it, and at some point the Spiral force Filmon to digivolve to Stefilmon.

After Herissmon's mind awakens from inside it tries to talk to the Spiral Hive Mind and stop it from continuing Fury Mode's rampage, however the Spiral refuse to listen and reject everything Herissmon tells it. Herissmon, with its new found knowledge that it is the Hive Mind's vessel, comes to the conclusion that it should also be able to control the Spiral just like how they had been controlling it and digivolves to Filmon. This angers the Hive Mind, and as the Hive Mind tell Filmon it cannot stop its rampage on its own, Filmon digivolves to Stefilmon.

When Herissmon, the Protagonist, and hunt down 's avatars in a Digital Point to prevent them from realising in the Real World, Herissmon and Tentomon digivolve to Filmon and  to fight against the Kuramon and Keramon. After Kabuterimon kills some of them, an Infermon spawns. As Filmon and Kabuterimon continue to fight the Keramon and Kuramon, Kabuterimon attempts to Super Digivolve, however Infermon attacks Kabuterimon before it is able to. Filmon then attacks Infermon to buy time for Kabuterimon. This allows Kabuterimon to Super Digivolve to, who then proceeds to defeat Infermon. Since there were still many more avatars however, Filmon Super Digivolves to Stefilmon to fight them.

Months after the incident, no Digital Points have opened due to Herissmon and the Spiral resting within. After the Digi-Egg hatches, the Spiral are freed and when the Protagonist and return from their vacation a new Digital Point opens up. Pusurimon tries to ask the Spiral why they had opened up a Digital Point however before they can answer they are enveloped in a dark aura and attack the group. As they fight and defeat the Spiral, more powerful ones continuously replace the ones they defeat and so Herrismon eventually has to digivolve to Filmon to be able to defeat them. The Protagonist was initially worried about letting Herrismon digivolve, though it convinces its partner to believe in it and that everything would be okay.

As they travel around the Digital World Mon is about to explain what being the messenger of the Digital World means, however Herissmon suddenly senses a group of Spiral. The group follow Herissmon and find a group of Spiral attacking a group of Gotsumon. Herissmon digivolves to Filmon and defeats them alongside and.

As Stefilmon fights, , 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.

After Filmon takes an attack from a Chaosdramon to protect Takumi and DoruGreymon, Filmon is overcome by a dark aura and demands more power so that it can protect the duo and digivolves to Stefilmon - despite the protests of the rest of the group. This pleases the Chaosdramon as it has found an enemy strong enough to rival its power, and Chirinmon and GrapLeomon decide to team up with Stefilmon to fight the Chaosdramon. As they fight, Takumi eventually realises that he can't do everything on his own and that his friends are there to help him, which causes DoruGreymon to digivolve to, and the group team up and eventually kill the Chaosdramon. After Stefilmon de-digivolves back to Herissmon, it states that it heard many voices talking in its head which cause it to lose itself, and Herissmon begins to worry about if its is going to be okay.

The Spiral then posses Stefilmon, forcing Stefilmon to go on a rampage. The Spiral's influence increases Stefilmon's power and Stefilmon easily beats down GrapLeomon and Chirinmon. During the battle Gatomon digivolves to and uses its "Heaven's Charm" to remove the Spiral's control, however it doesn't last very long and the Spiral possesses Stefilmon again. Chirinmon then uses its "Holy Wave" which fully removes the Spiral's possession, reverting Stefilmon back to Herissmon and ejecting the Spiral out of its body.

Some time after the Spiral force Herissmon to digivolve to Filmon, they force it to digivolve once again to Stefilmon, and Stefilmon is found by Michi and Angewomon in a Digital Point. They are unable to reach Stefilmon however, as more and more Spiral spawn to stop them and Stefilmon leaves, not wanting to kill it friends. It is then found by Mayu and Chirinmon, however the Spiral once again stop it from reaching Stefilmon. Eventually the group reconvene and find Stefilmon where the Protagonist and Herissmon first met however the Spiral trick it into thinking that the Protagonist had replaced it as its partner with Agumon 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. Stefilmon teams up with the nearby Spiral to fight Gaiomon, Angewomon, GrapLeomon, and Angewomon and during the fight the Spiral all fuse with Stefilmon to become.

Even more spawn however, and the during the endless battles against the rest of the avatars they find that the Diaboromon slow down when they revive themselves due to the amount of data they have to process, which in turn slows down the real Diaboromon that Omegamon is in the middle of fighting. Eventually Omegamon kills the real Diaboromon thanks to the work of the trio killing so many of the Diaboromon avatars.

This still isn't the end of it however and even more Spiral-2020B spawn though they are all defeated by who had just arrived with  in search of the Protagonist.

After being sent to the Digital World through a portal the Protagonist and Herissmon wander around, and are eventually reunited with Michi and Salamon. They defeat a group of Gazimon that assumed the group were trying to steal their homes and later hear the same Gazimon scream in the distance shortly after they had ran away. After arriving at the scene they see the Gazimon being attacked by a Mamemon and so Herrismon and Salamon warp digivolve to Stefilmon and Angewomon to defeat the Mamemon. They agree with the Gazimon to help deal with the Mamemon and the Gazimon take them to their secret hideout where they lived with a group of other Digimon that had also been chased out of their homes by the Mamemon.
