Character from Ben 10 by Man of Action / Cartoon Network
A round, armored alien from a destroyed planet who curls into a near-invulnerable ball and becomes a living wrecking ball — the first additional alien Ben unlocked, by accident.
Cannonbolt is a classic case of Ben weaponizing something that wasn't designed as a weapon. Arburian Pelarotas used their rolling ability for defense — protection, not offense. Ben turned it into a projectile. In ball form, Cannonbolt is nigh-invulnerable: he's survived falls from orbit without damage, absorbed energy blasts, and smashed through structures without slowing. He can accelerate to significant speed by bouncing off surfaces, building momentum like a pinball. He can house people and objects inside his shell, protecting them with the same armor. In bipedal form he's awkward — top-heavy and clumsy, which is the body built for rolling, not walking. He's the alien Ben never asks for and keeps finding useful.
A stocky, cream-yellow alien with large white armored plating covering his back and shoulders that folds around him when he curls into ball form. Four black claws, a wide stance, and the body language of someone who knows they're harder to hurt than anything nearby. When rolled up, he's a perfect sphere of interlocking white armor with no obvious weak point.
