Bio: Edward Nigma is a criminal mastermind who finds it so necessary to be the smartest person in any given room that he undermines his heists by leaving riddles that are inevitably doped out by Batman, leading to Nigma's capture.
I was surprised to find that I either never ran the Trickster in our first March Madness competition, or didn't set down any record of his participation. It took me a while to get around to his bio, so maybe I overlooked him. The truth is, Tom Trent only appeared in plain clothes in one story where he never got to use any of his gimmicks and all of his criminal career was reduced to a touch of exposition. Worse, he was outshone in context by the appearance of the Human Squirrel, and his name was actually stolen from a well liked Flash villain who debuted a year earlier. I obviously considered pitting Trent against James Jesse or Axel Walker, but I figured my alternate choice made Tom's life troubled enough. I have a fondness for the Riddler that dates back to Frank Gorshin's portrayal on the '60s TV show, and while he's hardly the flashiest or most deadly Dark Knight foil, he's certainly smart enough to outwit the Alien Atlas' off-brand Trickster.
