Cannonbolt is a hulking, broad-shouldered extraterrestrial covered in natural armor plating. This armor can resist almost any harm, ranging from acids to lasers to extreme heat.
By curling up into a ball, much like an armadillo or pillbug, Cannonbolt is able to encase himself in this armor, and thus become a seemingly invulnerable ball. He can then spin himself like a wheel, rolling into enemies at high speeds to attack.
There is a drawback, however: Cannonbolt has trouble slowing down once he gets going, which can make hitting more maneuverable targets difficult for him, and likely, others of his species (although in essence they may be better at their aiming). In addition, Cannonbolt's speed and maneuverability is limited outside of his ball form, owing to his bulk and high center of gravity, making him significantly slower and more deliberate in his movements.
- Cannonbolt's home planet was destroyed by The Great One shortly before Ben Tennyson discovered this form.
- Cannonbolt was originally meant to be one of the original ten aliens that Ben Tennyson had in his omnitrix, but was eventually replaced by Diamondhead during production.
- Cannonbolt eventually replaced Ghostfreak in the opening theme.
- The information from the Bandai Alien Collection toy for Cannonbolt refers to his species as a Vulpinic Tortugan (tortuga is Spanish for "turtle") from the planet Vulpin, which Wildmutt also originates from. However, it is to be assumed that the toyline is not canon when in conflict with the show's information.
