COPYCAT

Ok, this is where it really gets confusing.  Tyler Dayspring aka Genesis is a Mutant Liberation Movement (White Anglo Saxon protestant men claiming to be victims of bigotry simply because they are born with superpowers) leader operating under the nickname Mister Tolliver.  He's also the biologic son of Nathan Summers aka Cable and possibly Neena Thurman aka Domino, the nephew of Rachel Summers aka Phoenix II,  the grandson of Scott Summers aka Cyclops and Jean Grey aka Phoenix, the grand-nephew of Alex Summers aka Havok, also the great-grandson of Major Christopher Summers aka Corsair and the late Katherine Anne Summers (Major Christopher Summers (after the death of Katherine Anne Summers) is the leader of the Interplanetary super-hero team the StarJammers).  Tyler Dayspring is fixated on murdering his father Nathan Summers to such an extent that he hires a female mutant shapshifter named Vanessa Geraldine Carlysle aka Copycat to impersonate Nathan Summers' girlfriend Neena Thurman aka Domino.  This is ruined when the real Domino shows up.  So when Vanessa Carlysle chokes and refuses to kill Nathan Summers and ends up joining X-Force as a super-hero, Wade Wilson was brought in to expose Vanessa Carlysle as a traitor, got her kicked off the X-Force Team and kill Nathan Summers along with his X-Force Team.  Even that failed. 
So a girl who first appeared as a Neena Thurman aka Domino impersonator in the comic book New Mutants #98 on February 1991 and as herself in the comic book X-Force #19 on February 1993 began a lucrative career as one of the greatest sworn arch-enemies in X-Men comic book history.  While Wade Wilson eventually sought redemption to become a super-hero, Vanessa Carlysle aka Copycat continues to be bad to the bone and is always trying to get Wade Wilson aka Deadpool to fall off the wagon and become evil again.  Hey, he ruined her efforts to seek redemption, so it's only fair that she should ruin his efforts to seek redemption as revenge.  Here we have Morena Baccarin as Vanessa Carlysle aka Copycat and Ryan Reynolds as Wade Wilson aka Deadpool (Before his character was disfigured beyond repair by third degree burn injuries of a never disclosed origin).   This scene is from the upcoming Marvel Comic Studios Summer 2016 super-hero film Deadpool.
