Darwin

After birth, Darwin's powers of self-protection and continuous circumstantial evolution made his mother hate him. The Afro-Hispanic boy was found by scientists who experimented on him, bringing him to the attention of the public. He was found by Moira MacTaggert and recruited as one of her "fosters". He was in the first team, along with Kid 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. Rachel Summers managed to expel Darwin's presence from Vulcan, who then took off for space. While dealing with the shocking revelations of the truth about Krakoa and Vulcan, Beast found out that Darwin was in fact still alive. He was brought back to the Institute, where Beast determined Darwin was now a being of pure energy. While not conscious, he was shown to still have brain activity and was still alive, located at the X-Mansion. Once separated from Vulcan, Darwin's abilities caused him to develop a physical form once more.
