|Mega||Rasenmon Fury Mode|
An excitable, young Digimon, Herissmon lives in the Protagonists phone, and wants to explore the human world. He is very loyal and caring to his partner.
- Lightning Quills (Lightning Fur): Attacks the opponent by shooting lightning-coated quills.
- Needle-Point Dive (Kenzan Dive): Curls its body up into a ball and charges forth.
After being killed as Rasenmon Fury Mode, he reverts back into a Digi-Egg.
Pusurimon leaps out of the Protagonist's smartphone to protect them from a Keramon-shaped Spiral. Pusurimon puts up a good fight but is nearly defeated. After encouragement from the Protagonist, Pusurimon digivolves into Herissmon and defeats the Spiral.
After SkullGreymon reverts Greymon back to Agumon and paralyses Dorugamon, Gatomon, and Reppamon, Herissmon digivolves into Filmon due to wanting to protect the Protagonist and their friends. The Spiral all freeze up, and Filmon defeats some of the nearby Spiral and then attacks SkullGreymon. The Spirals freezing allows Leomon to join the fight, and the Champion level Digimon fight against SkullGreymon. Agumon then re-joins the fight, digivolves to MetalGreymon, 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 Lopmon are searching for Terriermon, 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, Elecmon, Michi Shinjo, and Salamon go to the park where Nozomi Tamada and Pumpkinmon were playing when a Digital Point opened up, Herissmon digivolves to Filmon to help fight the Spiral alongside Pumpkinmon, Leomon, and Gatomon. The Digital Point is eventually stopped by GrapLeomon.
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 Stefilmon.
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 Herrismon would go on a rampage again.
When Herissmon, the Protagonist, and Tentomon hunt down Diaboromon's avatars in a Digital Point to prevent them from realising in the Real World, Herissmon and Tentomon digivolve to Filmon and Kabuterimon 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 MegaKabuterimon, who then proceeds to defeat Infermon. Since there were still many more avatars however, Filmon Super Digivolves to Stefilmon to fight them.
- Crimson Slash: Whirls in a continuous slashing attack with both claws.
- Lightning Stinger: Skewers the enemy and injects energy into them that destroys their data.
After Filmon goes berserk and loses control whilst fighting a large group of Clockmon type Spiral, a SkullMeramon type Spiral spawns and attacks Filmon, which causes Filmon to digivolve to Stefilmon due to his desire to want to protect his friends. Stefilmon easily defeats the Spiral, however this doesn't calm Stefilmon down who then proceeds to attack his friends during his rampage. As Stefilmon fights GrapLeomon, Dorugamon, and Agumon, 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. This rampage causes the group to tell Herissmon not to digivolve any more just in case it goes on a rampage again, and after Dorugamon digivolves to DoruGreymon it tells Herrismon it will deal with Stefilmon should it rampage again in the future.
When Diaboromon tries to use the Digital Points to allow itself and its avatars to realise in the Real World, Omegamon asks Alphamon for help to deal with it. After Omegamon and Tentomon search for Alphamon, they find it with Herissmon. After explaining the situation, Herissmon and the Protagonist ask to help, and Alphamon asks Omegamon to fight Herissmon so that Herissmon and the Protagonist can learn from Omegamon. Herissmon warp digivolves to Stefilmon and fights Omegamon and after Stefilmon puts all of its power into an attack against Omegamon, Omegamon is impressed and states it has more than enough faith in its partner and battle experience to help Omegamon and Alphamon deal with Diaboromon and its avatars. After Filmon buys time for Kabuterimon to Super Digivolve to MegaKabuterimon, MegaKabuterimon defeats an Infermon avatar, and then Filmon Super Digivolves to Stefilmon to help MegaKabuterimon fight the rest of the Keramon and Kuramon avatars. As they're fighting them, multiple Diaboromon avatars arrive and attack the two Ultimates, however Alphamon suddenly arrives and defeats the Diaboromon avatars saving Stefilmon and MegaKabuterimon. 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.
Rasenmon Fury Mode
Rasenmon Fury Mode is Herissmon's alternate Mega form. When confronted by a large group of spirals, Stefilmon is forced to fuse with them all, which causes him to dark digivolve into Rasenmon Fury Mode.
Rasenmon is Herissmon's true Mega form.
After fighting his friends as Rasenmon Fury Mode, Stefilmon manages to come to his senses, and digivolves to Rasenmon. He then attacks the red eyes within himself, which causes Rasenmon Fury Mode to die, and revert back to a Digi-Egg.
