Abigail Wright, also known as Mercy, was a villain in the Marvel Comics.
Mercy[]
Mercy was an alien that came to Earth to kill those who lacked the strength to commit suicide. She only killed those that wished themselves dead and hated themselves, and thus she believed she was doing Earth a favor. When she came across the Hulk, who hates himself as well, she tried to make him commit suicide, but she failed. The Hulk could never stop fighting, as he feels he always has to be the strongest one.
Powers & Abilities[]
Mercy has the ability to teleport and read people’s mind. She also has the power of levitation. Her only offensive powers consist of creating energy spears that can kill anyone who is impaled by them instantly.
