This requires some explaining.

In Megaman 3 you encounter the Doc Robots. They each have the abilities of a megaman 2 robot. An image of that robot lowers from the ceiling into the doc robot. I had a simple solution for this. Instead of redesigning them all as animals I simply drew their weapons so now their weapon parts go into the doc bots. I had to think of what each weapon might look like. Each one has some of the boss's personality in it.
