Cannonbolt

Cannonbolt is the Codon Stream's DNA sample for an Arburian Pelarota from the destroyed planet, Arburia.

Appearance
Cannonbolt is a hulking, broad-shouldered alien covered in natural, yellow armor plating on its back, shoulders and the backs of his arms. He is mostly white with black on his upper half. Each hand of his posseses claws. He originally had sharp teeth, but in Alien Force, they are now human-like (hinting Arburian Pelarotas don't grow all their teeth until their teenage years).

Cannonbolt wore the Omnitrix was on his forehead in the original series and on his chest in Alien Force. Cannonbolt wears the Ultimatrix symbol on his chest in Ultimate Alien.

Powers and Abilities
Cannonbolt's shell can withstand acids, lasers, lava and even a G-force drop from space without any harm to the inside of the ball. Cannonbolt can roll into a ball like an armadillo or pill bug to encase itself in this plating. There is enough space within the shell while rolled up to protect and transport other fairly big things. When in the form of a rolled-up ball, Cannonbolt can increase its rotational momentum and roll into enemies as an attack, as well as ricocheting himself off surfaces. By spinning rapidly, he can create a tornado like XLR8 and Terraspin.

Weaknesses
Cannonbolt is subjected to the physical laws of reflection and conservation of momentum, meaning that he has difficulty stopping or controlling its direction if it picks up speed.

Cannonbolt has the Dark Heroes and the DNA Force skin. Cannonbolt is needed for defeating the Snap Dragon.

Ben 10 Alien Force: Vilgax Attacks
Cannonbolt replaces Alien X, but is replaced by Upchuck in the DS version.

Trivia

 * Cannonbolt was supposed to be one of the original ten aliens in the Ben 10 series, but was later replaced by Diamondhead.
 * Cannonbolt's weaknesses are that he can roll much faster than he can walk and he is so heavy that he tends to fall down a lot and a sticky adhesive can render Cannonbolt defenseless.
 * In the original series, Cannonbolt could not walk that far, but in Ultimate Alien, he is shown to walk faster and for longer distances but still relies on his ball form.
 * In the episode The Big Tick, it was revealed that Cannonbolt's home planet (where the rest of his species live) has been destroyed by The Great One a week prior to the events of the aforementioned episode.
 * Cannonbolt was the first additional alien in the original series and Alien Force.

 * Once, the Cartoon Network Ben 10: Ultimate Alien description of Cannonbolt had his original series appearance.
 * While rolling in The Transmogrification of Eunice he was able to turn ultimate. Possibly using his arms while he was rolling, or he else would not have been able to touch the Ultimatrix.
 * Cannonbolt's shell was orignally going to be green.
 * In the original series Cannonbolt has yellow eyes and his Omnitrix symbol is on the top of his forehead, but in Alien Force and Ultimate Alien he has got green eyes and his Omnitrix/Ultimatrix symbol is on his belly.
 * Cannonbolt has been used by almost all the Bens (10, 15, 16, 30 and 42 years) and also by Gwen in Ben's body, also has a Sumo version and is one of those with an Ultimate Version.
