10 Worst Things Martian Manhunter Has Ever Done
9. He Failed To Save John Jones
J'onn travels the world while taking on the form of a human so he can experience mankind through different cultures. He has taken on many identities including a thief from Dubai called Pearl, an FBI agent called Daryl Wessel, and a retired Japanese man called Yuchiro Takata.
However, J'onn's most well-known identity is of the private detective, John Jones. However, J'onn didn't invent this character. John Jones was a real detective that J'onn monitored to help him understand human behaviour.
When Jones was going to court to testify against a crime lord, two cops came by to make sure he got there without incident. Little did he know that they police officers were dirty and they were hired to kill Jones.
Since J'onn is telepathic, he instinctively could tell the cop, Kawicki, was corrupt, and so disabled him before he pulled his gun on Jones. Corruption is such an alien concept to J'onn, he decided to tap into Kawicki's mind to understand why he would betray a fellow officer.
Sadly, this moment of curiosity distracted J'onn long enough for the other cop to shoot Jones dead. J'onn took on Jones' identity as a way to make amends for failing to save his life.
