Cannonbolt is the Codon Stream's DNA sample for an Arburian Pelarota from the destroyed planet, Arburia.
Cannonbolt is a hulking alien with sharp claws. He also has the ability to transform into a ball. This armor can withstand acids, lasers, and even a G-force drop from space without any harm when he is in ball form.
Cannonbolt demonstrated his extremely tough plates in Ben 10: Secret of The Omnitrix when he broke through three electric, metal doors in order to get to Azmuth, the creator of the Omnitrix. However, it is subjected to the physical laws of reflection and conservation of momentum, meaning that it has difficulty stopping or controlling its direction if it picks up speed. By spinning in the same spot rapidly it can create a tornado like XLR8 and Terraspin .
Cannonbolt's armored shell is a defensive mechanism that is extremely resilient (but because of Ben's creativeness he has adapted this to attacks). The shell is durable enough to survive a free fall from the upper limits of the Earth's atmosphere and including the heat of atmospheric re-entry, and still leave Cannonbolt and anything held inside the ball intact, though the landing still creates some pain due to the large crater left there. So far, nothing has been seen that can penetrate the shell.
If Cannonbolt is in a spot where he can not get up where he is stuck to the ground and he can not get up, he can be consitered useless as seen in Video Games where he was stuck to the ground and could not get up.
