10 Worst Things Martian Manhunter Has Ever Done
7. He Erased His Teammates' Memories
Stormwatch was originally a part of Wildstorm Comics but was absorbed in DC Comics in 2011. Martian Manhunter joined this incarnation of the team.
Stormwatch is a cosmic organisation sworn to protect Earth from intergalactic or interdimensional threats. The enemies they face are so immense, Stormwatch consider superheroes like Superman and Batman as "amateurs". To give you an idea of what sort of threats they face, Stormwatch battled the freaking Moon in their first story under the DC banner.
The team has saved the Earth, the universe, and everything in-between for millennia. Nevertheless, J'onn felt like he didn't belong and decided to depart.
But there's a problem. Members of Stormwatch told humanity of their existence once and it led to hundreds of thousands of deaths. Since then, the existence of Stormwatch has been kept secret. To maintain the secrecy of the group, members live in a space station in-between universes and are not allowed to venture to Earth unless it's for a mission.
When J'onn realised the team wouldn't allow him to leave, he wiped their memory of his time in the group and left to forge his own path.
