Lenoben is the Omnitrix MK10's DNA sample of a Lenopan from an unknown planet.


In The New Omniverse, Lenoben has purple skin and a little pink mud-like skin also. He has muddy pink hair and green eyes. He wears the Omnitrix MK10 on his chest.

Powers and Abilities

Lenoben can stretch, morph and shape shift his body in any way shape or form at will, as well as changing his color and texture. If he stretches too far, it might result in the part falling off. He can detach his body parts, and stick them back on, reattaching them. If he is disembodied, his pieces will instinctively come together again and reconstitute him.

Lenoben can shapeshift his body parts, and sometimes himself into other objects. Using his sludge, he can look like another shape made of purple sludge, while he can still move while in liquid form. His ability to mimic color and texture allows him to mimic flesh or fabric exactly. He can also shapeshift into non-existent or imaginary species complete with unique abilities. He even can morph his body parts into melee weapons.

His liquid body can also be gelatinous, to the point where he is like large masses of muscle tissue, allowing him to be tangible and giving him the ability to physically interact and be mobile. His body also generates slime, resulting in person jump through him, only to be covered with it, him being able to fire sticky sludge to subdue a target like webbing, and him being capable of regeneration and growing back parts of his body.


Lenoben can be harmed by water, fire, or by scattering enough of his body matter to the point where he cannot reconstitute. He will dissolve in water and turn the water purple, as he is unable to change out of liquid form, and fire will cause him to turn into brittle statues. However, both of these methods will only neutralize him and are not lethal.


  • Lenoben debuts in 10+10, where he briefly fights Jen.
