10 Worst Things Martian Manhunter Has Ever Done
8. He Lies To Everybody
When J'onn takes the form of John Jones, his co-workers assume he is a regular police officer and are oblivious to his alien heritage.
However, J'onn's secret identity is much more complicated than that. John Jones has a reputation for having a sixth sense with solving cases. J'onn is able to do this because he's using his telepathy to peer into people's minds and using their intel to solve cases quicker. If his companions knew J'onn was doing this, they would feel like he was violating their privacy.
But it gets worse. While on a private case as Jones, J'onn was exposed to a deadly cloud. Since this gas was lethal to humans, J'onn had to pretend that it killed Jones.
His workers were devastated that Jones "died" and spent months grieving for him. J'onn couldn't come forward to his former colleagues and admit that he was Jones since his actions would be misinterpreted as some sick mindgame. Instead, he revealed himself to the team in his Martian form and said he would avenge Jones' death. Although J'onn hated lying to them, he knew the truth would cause more harm than good.
