Seems cool! Craze and Zap are unfortunately overpowered on purpose though so it wouldnt be too fun. Craze is a mass of self replicating Nanobots so if he wanted to, he could eat the whole universe. His only weakness is being separated from Zap, because it needs to feed off of zaps unlimited energy core. Without that its self replication would slow and then any damage done to craze would be remain until he rejoins with zap. And when joined with Zap, they can self heal forever. Zaps armor only being penetrated by the same material he is made of or high intensity energy weapons. They are supposed to be cartoony cuz them dying isnt supposed to be an issue in my series.
