Cannonbolt (a play on cannonball) is an Arburian Pelarota (a play on the Spanish word pelota, which means 'ball', and rota a play on the word 'rotation'). It is the first new alien to appear on the Omnitrix. Cannonbolt's first appearance was in the episode The Big Tick . Despite Ben's initial dislike of the form, it has since become one of the most commonly used forms in the series and replaced Ghostfreak in the opening theme as Ghostfreak had escaped from the Omnitrix at the time. However, it was said that Cannonbolt was supposed to be one of the 10 aliens Ben started with, but somehow it got changed to Diamondhead by popular demand. Cannonbolt was a runner up in the Cartoon Network Ben 10 alien poll. Cannonbolt was first voiced by Fred Tatasciore and on Gwen she was voiced by Vanessa Marshall.
