The turtles, Mighty Mutanimals, and April set out to stop Shredder and Krang's destruction.
- Be Careful What You Wish For: When Krang and Shredder inform them that they're to become their new partners, Bebop and Rocksteady are so excited they grab each others hands and squeal in delight, with big pink hearts in the background. But they quickly find out that their plan is to destroy the world, they are understandably shocked and later pull a Heel–Face Turn.
- The Bus Came Back: Traag and Granitor return as part of Krang's invasion force. This also doubles as a case of Back for the Finale.
- Call-Back: Two episodes ago, '87-Leonardo dismissively mentioned how Shredder and Krang's motivations tend to flip-flop Depending on the Writer, their plans ranging from Take Over the World, destroy the world or "whatever." Here, after claiming that they plan on conquering the 2012 Universe all this time, declare that they intend on using the technodrome to destroy it. It's hearing this that leads to Bebop and Rocksteady sabotaging their plan.
- Even Bad Men Love Their Mamas: This is how Bebop persuades Rocksteady to rebel against Shredder and Krang.
- Even Evil Has Standards: Bebop and Rocksteady like the world and thus don't like Shredder and Krang's desire to destroy it.
- Grand Finale: The official series finale.
- Heel–Face Turn:
- Bebop and Rocksteady help the turtles and Mutanimals turn the tide of battle. They also give up on the super villian business and become super heroes, though if Bebop's rant is anything to go by, they're doing it for fame and luxury.
- Once their in their home dimension, the 80s turtles tell the 80s Bebop and Rocksteady that they don't have to obey Shredder and Krang.
- Honor Before Reason: While displeased with Shredder and Krang's desire for world conquest/destruction, Rocksteady says they can't leave after they were made equal partners since he thinks it would make them lowly cowards.
- Mythology Gag:
- Much like in Turtles Forever, another cross-over between the contemporary and 1980's Turtles, Bebop and Rocksteady prove to be the villains' undoing, albeit under different circumstances.
- The episode shares the same title as the third season finale of the original 1987 cartoon.
- Pet the Dog: Shredder and Krang of all people get one, apologizing for treating Bebop and Rocksteady so badly, admitting they were just acting that way because the Bebop and Rocksteady of their universe was so useless. They even offer to make the mutants partners instead of henchmen. Too bad it's followed by them deciding to destroy the world.
- Likewise, when the '80s Turtles come back to their dimension with Shredder and Krang on tow, they decide to take it easy with their Bebop and Rocksteady by suggesting to them that they don't have to be Shredder's lackeys and they should just be whatever they want to be.
- Ship Tease: When Krang and Shredder inform them that they're to become their new partners, Bebop and Rocksteady grab each others' hands and squeal in delight, looking each other in the eyes with big pink hearts in the background. Bebop calling Rocksteady "baby" in this context stands out in particular.
