Layla Miller

Layla Rose Miller, also known as Butterfly, is a fictional character appearing in American comic books published by Marvel Comics. She first appeared in House of M #4 (Sept. 2005), and was created by Brian Michael Bendis and Olivier Coipel. Peter David later developed the character, placing Layla at the center of the ensemble of mutant private detectives in his title X-Factor. Layla Miller is a mutant with the ability to resurrect the dead, albeit without their souls. She is a key figure in the reversal of the House of M reality, as she helps return the memories of other characters. The character initially seemed to have an extensive knowledge of future events, claiming that she "knows stuff". This was revealed to be a product of time travel within her own timeline, where a future version of the character uploaded memories into her younger self.
