Ultimate Cannonbolt

Ultimate Cannonbolt is the evolved form of Cannonbolt.

Appearance
Ultimate Cannonbolt changes Cannonbolt's soft white and yellow skin into hard light metallic blue skin. Ultimate Cannonbolt's shell has changed into a more metallic shell with cylindrical studs that turn into spikes when he goes into his ball form. He has two on each back segment and one on each shoulder, wrist and leg plates. Ultimate Cannonbolt is also a little bigger than Cannonbolt. He can contain radiation.

Ultimate Cannonbolt wears the evolved Ultimatrix symbol on his chest.

Powers and Abilities
Ultimate Cannonbolt has powers similar to Cannonbolt's, but instead of having a simple armored shell, the shell has become metallic, spike-covered armor that offers increased defense and offensive abilities therefore he can do more damage than Cannonbolt can, enough to hurt Ultimate Aggregor. Also, in The Transmogrification of Eunice, he is able to take hits from Sunder's energy axe, only being pushed back.

Ultimate Cannonbolt also has increased speed, momentum and can bounce higher. Considering he was able to hurt Ultimate Aggregor enough to back him into a corner, he could be one of Ben's strongest aliens. Ultimate Cannonbolt has enhanced strength, he was able to go head to head with Sunder alone and in It's Not Easy Being Gwen he punched Animo's mutated frog with his bare hands, sending it flying.
