Omni-Enhanced Cannonbolt is the Omnitrix's Omni-Enhanced version of Cannonbolt.

Omni-Enhanced Cannonbolt wears a large gray, blue, and green rock helmet around his body that completely covers his top and back. There are blunt rock spines sticking out of it.

Omni-Enhanced Cannonbolt wears the Omnitrix symbol on his chest.

Omni-Enhanced Cannonbolt retains all of his original powers, such as being able to curl into a ball, where he can move at great speeds within this form and even increase his rotational momentum in order to slam into and/or run over enemies. However, his enhancements further increase the impact of said attacks, and additionally give him a charge whilst rolling in sphere form.

While rolling, Omni-Enhanced Cannonbolt also makes motor noises and produces two trails of blue light from the two spikes on his sides.

The spikes running along Omni-Enhanced Cannonbolt's back (and around him in sphere form) can be fired out as explosive missiles.

Omni-Enhanced Cannonbolt has the same weaknesses as the default form, namely his being subjected to the physical laws of reflection and conservation of momentum, meaning that he subsequently has a more difficult time stopping or controlling his direction if he increases his speed too much.
