Ben10UA on Instagram: "Ultimate Cannonbolt is the evolved form of the alien Cannonbolt in the Ben 10: Ultimate Alien series. Unlike his original form, Ultimate Cannonbolt features a more armored and dangerous appearance. His shell is covered with large, sharp spikes, making him even more destructive when rolling at high speed. One of his key upgrades is enhanced durability and attack power. His spiked form allows him to deal more damage during combat, and he can crush enemies with great force. T
