The leader of the Punk Frogs. Upon meeting Mikey and learning about his brothers at the O'Neil Farm house, Attila sends Genghis Frog to "liberate" the Turtles from the humans, stating that the humans are the reason behind the loss of their environment and planning to use the Mutagen that Rasputin studies to invade the cities to get revenge on the humans. When the rest of the Turtles arrive, Attila fights against Leonardo. After being rescued from the fire by April O'Neil and Casey Jones, Attila sees that not all the humans are evil and promotes Napoleon Bonafrog to general upon seeing the wisdom in him.
