* EarWorm: The main action theme plays for roughly 85% of the game, so it's a damn good thing it's so catchy.
* DemonicSpiders: The ''very first'' gang that attacks you, on the first screen of the game, attacks faster and harder than almost every other set of mooks in the city. Your best bet for survival is to run immediately into the next screen.
* FridgeBrilliance: When you load a savefile, you must also specify a save file for the other main character, even if you decide to start out without him. If you do start alone, the other protagonist will confront and fight you at the end of the tire factory. When beaten, he will drop a usually large amount of money, although in some cases almost no money at all. Now, consider [[DeathIsASlapOnTheWrist you drop half of your money when you are knocked out]].
* GameBreaker: Stone Hands, Dragon Feet, or Grand Slam in the NES version. Acro Circus or Torpedo in EX, although your reputation will be trashed if you abuse them.
** Acro Circus was a gamebreaker in the NES version also, since the move won't trigger a block animation. Once that got mastered, your biggest fear was accidentally bouncing a box, tire, or trashcan into yourself.
** The double chain typically carried by The Eagles, which has insane reach and can be spammed just as fast as any other weapon. It gets even worse with Grand Slam.
* MemeticMutation: "BARF!"
