Powers and Equipment[]

Like all Osmosians, Kevin has the ability to absorb any material and coat the contacting part, or all, of his body in said material. Given enough material, he is then able to morph the coated parts of his body - except for his head - into anything he can imagine. He has used this for giant scissors, weapons, and shields. More recently, he has adopted wings for flight, though the material he absorbs is critical to this because certain ones are too heavy to allow it to be done or too light to carry his whole body.

Absorbing too much of a material, or absorbing too frequently, can lead to the mind being warped or going insane.

Absorbing living beings allows him to transform into that being or use their abilities on a localized part of his body.

Absorbing specifically energy from the Omnitrix conflicts with his abilities and often leads to him turning into a hybrid of a multitude of aliens.
