Peek-a-Boo is Lashawn Baez, a metahuman criminal with the ability to teleport. This has made her an enemy to the third Flash, Wally West. She was originally a student who turned to crime to pay for her father's medical procedures. Her distinctive outfit includes roller blading gear and clothing with smiley faces on it. Peek-a-Boo was created by Geoff Johns and Scott Kolins, first appearing in The Flash (Volume 2) #180. (2002)
