A new age begins for the Turtles as the epic events of the past have created new opportunities for the future, but new dangers as well. While they continue to get used to a world leading the Foot Clan post-Shredder, they return to the Technodrome to monitor the revival of the Utroms on Burnow Island and are surprised to meet a new mutant--Leatherhead! Will the mysterious mutant be friend or foe? Plus, Kitsune still poses a threat and a new group, the Street Phantoms, enters the fray!
