He's big, mean, massively muscled and nasty to behold! He's the evil time-traveling sorcerer Savanti Romero! Arch-enemy to the Turtles' friend Renet the Timestress, Romero is a constant pain in the shell... throughout time and space! He's pounded the Turtles in the present, past and now the paleolithic!
