Beware, lawbreakers! There's a new masked vigilante prowling the streets of New York City. He wears a hockey mask and wields a baseball bat. Look out for Casey Jones!
Tropes:
- All Crimes Are Equal: Not only does Casey stop muggings and burglaries, but he also harasses homeless people who loiter on park benches with equal brutality. Anyone who breaks the law, no matter how benign, are lawbreakers to Casey Jones!
- Black-and-White Insanity: Casey Jones genuinely believes in law and order and is out to clean the streets with nothing but his weapons. Unfortunately, All Crimes Are Equal to Casey Jones and the turtles have to stop him because of it. It also doesn't occur to him that masked-vigilantism and vandalism are also lawbreaking.
- Don't Try This at Home: Bebop and Rocksteady address the kids in the audience and say about as much with the way they cling to the moving subway trains.
- Good Versus Good: Casey Jones mistakes the turtles for criminals planning a heist in the sewers.
- Leeroy Jenkins: Casey Jones ends up getting himself and the turtles caught in Shredder and Krang's trap because he doesn't believe in being "careful."
- Medium Awareness: Two instances occur as part of their fourth wall jokes.
- When April and the rest of Channel 6's team is being attacked by the rogue appliances, April complains about what the turtles are doing to fix the problem, causing usual-fourth wallbreaker Raphael to pause fighting just to shut her down.April: Where are the turtles? Why aren't they doing something?!
Raph: Hey, give us a break! We're doing the best we can! (turns to face the audience) Some people are so darn impatient... - The final moment of the episode ends on this, courtesy of Casey Jones himself:Leo: Somehow, I've got the feeling he'll cross our paths again.
Casey: (turns to face the audience) Somehow, I got a feeling he's right.
- When April and the rest of Channel 6's team is being attacked by the rogue appliances, April complains about what the turtles are doing to fix the problem, causing usual-fourth wallbreaker Raphael to pause fighting just to shut her down.
- Moral Myopia: Everyone treats Casey Jones' rampage as a serious problem compared to the turtles, though the way he deals with criminals — using his weapons and the environment to non-lethally and non-permanently incapacitate criminals — isn't that all different from the way the turtles deal with gangsters and bank-robbers. Granted they draw the line at harassing homeless people loitering, but Donatello acknowledges that his methods make him similar enough to them where if they don't stop him, people will think they're responsible for his rampage.
- Off-into-the-Distance Ending: The final scene of the episode ends with Casey Jones walking off into the sunset after confirming that he and the turtles will meet again someday.
- Oh, Crap!: When the turtles unmask themselves to Casey, he mistakes them for martians and runs off.
- Shout-Out: Casey says "go ahead, make my night" to thugs robbing a sports-goods store, a reference to the line "Go ahead, make my day" from Sudden Impact. Raphael even lampshades that he's "seen too many [Dirty] Harry movies."
- Technopath: Krang and Shredder's scheme of the week is distributing robotic bugs that brings all the machinery in the city to life.
