A Martian, J'onn J'onzz came to Earth in an attempt to prevent The Joining from destroying it. While undercover for the majority of his stay, he eventually joined forces with Batman to destroy the Joining once and for all.

After the global threat was eliminated, J'onn later returned to Batman. Here J'onn transported them to a space station where Batman was introduced to a new "league" of heroes. This league, consisting of Green Arrow, Hawkman, Green Lantern, The Flash, J'onn and now Batman, is dedicated to saving the Earth against anymore global threats.
