Calmybara is the Omnitrix's DNA sample of a Hydrocessabit Faveochaeris from the planet Gelidus. He is a free use alien made by Alan.

Calmybara wears the Omnitrix on his front left leg.

  • Calmybara has a singular sharp tooth.
  • Calmybara is an excellent swimmer.


  • Calmybara's powers do nothing against an emotionless opponent.
  • Calmybara is a non-combative alien.

  • Calmybara's name is a play on "calm" and "capybara."
