Gesomon is a Mollusk Digimon. It has the shape of a squid and inhabits the depths of the Net Ocean. Although it is feared as the "White Demon of the Depths", it is highly intelligent and will not harm Digimon outside of its territory. However, if they seem to cross into its territory even for a moment, it will attack them like a fierce, raging god. For its attack style it specializes in "Hit and Away", in which it inflicts a single blow and then immediately withdraws.[2]


  • Coral Crusher[3] (Devil Bashing): Unleashes a barrage of attacks that capitalizes on its many legs.
  • Coral Crusher[4] (Deadly Shade) Attacks with a powerful squid ink that will completely numb the opponent's vision for a long time if they get hit by it.
  • Knight's Dome (Squire Dome)


Gesomon resembles a white version of the European squid (Loligo vulgaris). It has grey markings on the front of its mantle, metal tubes wrapping around its mantles and jaws where its mantle meets the arms. Its tentacle pads have three claws.

As Tai, Sora, Agumon and Birdramon scout the sea, they are attacked by a Gesomon who shoots down Birdramon, but Gomamon rescues them. Gomamon explains that when anyone tries to cross the strait, Gesomon attacks them like that.

In order to cross the strait, Gomamon lures Gesomon to shore, but when they get close, Gesomon strikes Gomamon, injuring him and flinging Gomamon to shore. With Gesomon on land, Agumon and Palmon digivolve into Greymon and Togemon to fight him. However, Gesomon drags Togemon into the ocean and wraps up Greymon who eventually forces Gesomon to let them both go. After Joe finally accepts his role as Gomamon's partner, Gomamon digivolves into Ikkakumon who, being a fellow sea animal Digimon, is unharmed by Gesomon dragging him underwater, ramming Gesomon into an underwater rock. Gesomon tries to flee, but Ikkakumon blasts him with his Harpoon Vulcan, sending Gesomon flying onto the shore. Taking advantage of this, Togemon and Greymon attack Gesomon, sending it fleeing back to the sea. Ikkakumon blasts Gesomon again with his Harpoon Vulcan, sending Gesomon sinking into the depths, leaving behind an inky cloud. That Boy is Joe Kido
