Darwin

Darwin
Name: Armando Muñoz
First Appearance: X-Men: Deadly Genesis #2 December 2005

"Always hard to make decisions. Always tough to know when to let go.
When to give up. When to know enough is enough.
And then there are some who never learn.
And then there are others who never know when enough is enough.
Who isn't stopped by common sense or even death? And people like that...you want to keep an eye on. Because you never know where they will lead you. " - Darwin

Moira MacTaggert recruited Armando as one of her "fosters". He was in the first team, along with Vulcan, Petra, and Sway to attempt to rescue the X-Men from Krakoa.

While Petra and Sway were killed by Krakoa, Darwin and Vulcan were swallowed in the earth by a combination of Sway and Petra's dying powers. Darwin absorbed the remains of the two girls and then converted himself into energy to fuse together with Vulcan. This gave Vulcan the powers of Darwin, Petra, and Sway and enabled him to survive in space, albeit in a dormant state.
