Cannonbolt

Cannonbolt is an Arburian Pelarota indigenous to the planet Arburia. Cannonbolt is in fact the first "new" alien to appear on the Omnitrix.

Appearance
Cannonbolt is a hulking, broad-shouldered extraterrestrial covered in incredibly durable armor plating. He also has

Powers
By curling up into a ball, Cannonbolt is able to encase himself in this armor, and thus become seemingly invulnerable. He can then spin himself like a wheel, rolling into enemies at high speeds to attack.

Weaknesses
Cannonbolt has trouble slowing down once he gets going, which can make hitting more maneuverable targets difficult for him. 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.
