Fan Casting And the Adventure Continues in Sort by Tropes

After a long fight, the Big Bad is finally defeated, his Evil Plan thwarted, his legions of robotic minions smashed to pieces, his living ones have been safely thrown in jail, The Dragon is dead, and the Quirky Miniboss Squad has decided to go straight and make a new life for themselves. Congratulations are given, the dead are mourned, the Unresolved Sexual Tension is resolved (or is about to be)... Uh-oh, there's another call for help! The Starscream (Or why not, a brand new Big Bad?) is causing trouble! No rest for the virtuous heroes, it's time to spring back into action! THE END Say what now?
