- Crowning Music of Awesome: The opening theme, "Showdown", which starts as a chill rap number before transitioning into energetic and soulful gospel choir. This trope also extends to the laidback R&B tune that is "Regardless", the anime's ending theme. Some reviewers admitted that they thought the show was mediocre at best, but still watched every episode because these two songs were just that good.
- Useless Protagonist: Philly the Kid is arguably one; he's mostly just a regular guy with a gun and a big car. If he weren't immortal he'd be completely outmatched by nearly every opponent he faces, from cyborg assassins to superhuman samurai.
YMMV / Cannon Busters
