Being the third smartest person in the world, Michael Holt is DC’s resident brainiac, forever on-call when one of the more muscle-bound heroes run into a problem that fists can’t solve. Taking on the guise of the new Mister Terrific, Holt manages to be both a consultant and an action hero in the comics as a member of the Justice Society of America and Checkmate.

If you want to get into Mister Terrific, pick up some Justice Society trades or DC’s ongoing Earth 2 series.
