Dave Johnson was one of the original designers on Ben 10. He showed off some concept art of Cannonbolt, Sixsix and a Megawatt (or a Nosedeenian as its later revealed). Check them out.

| Cannonbolt Concept Art |
Cannonbolto had the most different appearance compared to his final self. He had crab like legs, two mushroom like bulbs attach to his body, a small mouth that has antennas surrounding it as well as two arms. He wore the Omnitrix on his face like Stinkfly. The concept art says there would be small spray-can like rockets that would pop out of the bulbs to control where Cannonbolt would go. He presumably would encase himself within the two bulbs as he rolled around.
