Thetismon is an Aquabeast Digimon. It is a Digimon that has taken the form of a woman. It was discovered in the deepest trenches of the Net Ocean, the birthplace of Digimon. Thetismon brings peace and tranquility to its own vast territory and lays down the law on any Digimon that dare to disturb it. It has an ingrained need to help the weak and weaken the strong. As such, while it shows no mercy to Digimon who threaten its territory, it is kind to those in need of help, guiding them to safety. Thetismon eliminates invaders with its special moves.[3]


  • Shock Smasher (ビリースマッシャー Birī Smasher?): Utilizes electrical energy accumulated in its palms to send its fists flying.
  • Thunder Hammer (Hammer Thunder): Kicks an enemy up and then brings it down with the force of two electrically-charged fists.
  • Goodbye World (Adieu World, Fra: Goodbye World): Allows Thetismon to teleport by removing the space between it and its opponent.
  • Doctase (Dokutease[4]): Various medicines are generated and released from its tentacles. With this ability, Thetismon can heal allies' wounds and temporarily boost their powers. If used against an enemy, however, it will afflict them with a deadly poison that disintegrates them from the inside out.

Its helmet resembles a jellyfish's umbrella-shaped bell with a sun-like emblem which its hair resembles tentacles, the two longest of which having green ends.
