Granted, but the movie begins with Spider-Man getting amnesia after fighting the Sinister Six, making viewers wonder who else would be able to stop them.

I wish there was a crossover movie starring the 1987 TMNT characters and the 90's Sailor Moon characters teaming up to fight a common enemy (with most of their original voices aka Cam Clarke as Leonardo and Rocksteady, Barry Gordon as Donatello and Bebop, Rob Paulsen as Raphael, Townsend Coleman as Michaelangelo and Shredder, Renae Jacobs as April O'Neil, Peter Renaday as Splinter, Pat Fraley as Krang, Terri Hawkes as Serena/Sailor Moon, Karen Bernstein as Amy/Sailor Mercury, Katie Griffin as Raye/Sailor Mars, Susan Roman as Lita/Sailor Jupiter, Stephanie Morgenstern as Mina/Sailor Venus, Jill Frappier as Luna, Ron Rubin as Artemis, Vince Corazza as Darien/Tuxedo Mask, and a few more actors/actresses as new villains the two teams end up having to team up against to defeat).
