Directed by Jake Castorena. With Troy Baker, Eric Bauza, Darren Criss, Kyle Mooney. Batman, Batgirl and Robin forge an alliance with The Teenage Mutant Ninja Turtles to fight against the Turtles’ sworn enemy, The Shredder, who has teamed up with Ra’s Al Ghul and The League Of Assassins.
This ended up being a much better film than I was expecting it to be. This style of TMNT animation is new to me, but the characterizations and animations were spot on. They got bonus points for using one of Batgirl’s best costumes and for having the two villains team up in a way that made total sense.
