Four Arms! Plus four?

– Four Arms's first impression on Omni-Enhanced form.[1]

Omni-Enhanced Four Arms is the Omnitrix's Omni-Enhanced version of Four Arms.


Ben as Omni-Enhanced Four Arms

Omni-Enhanced Four Arms appears similar to regular Four Arms but with gray rock armor covering the upper part of his chest and shoulders. He has four blue hands, one pair of which replaces his upper hands, giving him six hands in total. He also wears a helmet around his head and has armor plating on his legs. Omni-Enhanced Four Arms wears the Omnitrix symbol on his chest.

Space Slime as Omni-Enhanced Four Arms

The Space Slime's Omni-Enhanced Four Arms looks identical to Ben's but has purple eyes.

Powers and Abilities

Omni-Enhanced Four Arms shares the same abilities as his default form namely his enhanced strength.

Omni-Enhanced Four Arms' extra pair of fists gives him even more strength than in his regular form, and also allows him to use even heavier objects around him, such as big rocks or beams/pillars, as something to fight or arm himself with. His blue hands double his punching impact, as well as also deploying energy while he punches or grabs.

Omni-Enhanced Four Arms can also create a supersonic shockwave by clapping his gauntlets together or slamming them on the ground. The stone armor on his body also increases his durability. He also has enhanced jumping.


Omni-Enhanced Four Arms shares the same weaknesses as his default form, namely his sheer bulk preventing him from accessing certain areas that prove to be too small for him.

Omni-Enhanced Four Arms' immense size also makes him a much easier target to hit.

Despite his enhanced jumping, Omni-Enhanced Four Arms could not jump high enough to reach Yawk.[2]
