Fan Casting Martian Manhunter in Earth-27 fancast (rewrite)

The Alien Atlas. The mysterious Manhunter from Mars is one of the JLA's longest-serving members. Although he arrived on Earth in the 1940s, J'onn laid low for decades before he felt comfortable revealing himself to humanity and quickly became one of the Justice League's founding members. Underneath his cold exterior is a warm and caring soul, and many consider him to be The Heart of the League.
