S01, E16 (First Aired: February 23, 2013) The Turtles meet their first fan when a teenager decides to dress up and fight crime as “The Pulverizer.”
I wonder who "The Pulverizer" could be? Is it a new character, or somebody from previous TMNT canon?
I would speculate that it's Casey, but he's not supposed to show up until Season 2.
