Ultimate Cannonbolt is the evolved form of Cannonbolt.


Ultimate Cannonbolt changes regular color from from white and yellow, to mostly blue, gray, and black. Ultimate Cannonbolt's shell has changed into a more metallic shell with round 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 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 much more damage than regular Cannonbolt can.

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 also 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.


  • Ultimate Cannonbolt is the only Ultimate form to not appear in Ben 10 Ultimate Alien: Cosmic Destruction.
  • According to the Galactic Racing site, Ultimate Cannonbolt can shoot spikes, according to Eugene, he believes Ultimate Cannonbolt can in the series as well, however this has yet to be seen.
  • Ultimate Cannonbolt does not seem to lose momentum when he bounces around, regardless of the spikes sticking out of his shell. According to Dwayne, the spikes just give him more friction.
  • In all of his appearances, Ultimate Cannonbolt is the last alien used in that episode.
