Possibly the most tormented person in the League. J'onn Jones witnessed the destruction of his planet and death of his family. Being the sole survivor of Mars, J'onn made his way to Earth to watch over it and protect it as superheroes became more and more prominent on that planet. He's calm, caring and understanding.

J'onn can be seen as quite blunt, yet the members of the League seem to sway his way when under emotional stress. He provides a shoulder to cry on. At the same time he's a unique fighter, preferring to talk his way out of conflict he will not hesitate to use his plethora of abilities to stop his enemy.
