Following the idea that captains have names of mythological beings, I named myself the hero Cambion. The Cambion creature has many abilities but the best known is to change shape.
mine was prototype. Because his abilities up to that point made me think of that game. But it really didn't hold up in the long run
I named him Alex, as a reference to prototype
I similarly followed the mythological theme and went with Atlas. Seemed fitting to me.
