Synopsis:
The Martian Manhunter donates his services to charity. He agrees to perform missions for contest winners who contributed to the charity. Each winner ask J’onn to retrieve a rare object. J’onn completes each mission successfully.

Later, a man wearing the mask J’onn retrieved from a jungle tribe, robs a bank. The mask gives him teleportation abilities. J’onn suspects the man is the contest winner, but he checks the man’s background, learning the winner was already rich. He then suspects the contest organizer, Roger Hawkins. J’onn locates Hawkins, separates him from the mask, then apprehends him. J’onn destroys the mask in the process.
