Humungousaur before going Omni-Naut.[1]

Omni-Naut Humungousaur is the Omnitrix's Omni-Naut version of Humungousaur.


Omni-Naut Humungousaur is covered in orange, white and gray metallic space armor. His arms are covered in orange plating, his shoulders have neon green lights and white plating, the mace on his tail is cylindrical with grey spines running from his neck and back, his feet are black with neon green outlines, and his head is covered in a square-shaped orange and grey helmet with a secondary Omnitrix symbol (turned sideways) on the face.

The Omnitrix symbol is located on his chest.

Powers and Abilities

Omni-Naut Humungousaur shares the same abilities as his base form, namely his spiked mace tail.

Omni-Naut Humungousaur can fly thanks to his jetpack.


Omni-Naut Humungousaur can be downed by sustaining damage to his jetpack.

There is a limit to how strong Omni-Naut Humungousaur is, as he could not penetrate through the Incursean Ship's door.
