Cannonbolt

Cannonbolt is an Arburian Pelarota indigenous to the planet Arburia. The Pelarotan home planet was destroyed by the Great One shortly before Benjamin Tennyson discovered this form. Cannonbolt is in fact the first "new" alien to appear on the Omnitrix. He 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, he 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.
