The Turtles have entered the Battle Nexus Tournament, but behind the scenes all is not well...
This episode provides examples of:
- Big Damn Heroes: Leonardo is about to be killed by Draco's mooks, but he's saved by Usagi.
- Bitch in Sheep's Clothing: The Ultimate Ninja is pretending to be friendly to the Turtles, but in reality he hasn't changed at all.
- Evil Is Petty: The episode ends with the Ultimate Ninja shooting Leo with a poison dart. Doing so has nothing to do with his plan to usurp his father as leader of the Battle Nexus; he does it purely out of spite and wounded pride for Leo defeating them in their previous duel.
- I Let You Win: Splinter lets Mikey win in their battle in the tournament. Usual in that Mikey is well aware that his sensei is forfeiting in his favour.
- Magical Land: The Battle Nexus.
- Tournament Arc
