Worst Compatibility, Rin and Karen is the 8th episode of Yes! Pretty Cure 5, and the 153th episode overall of Pretty Cure.
Rin and Karen can't get along.
Tropes:
- Back-to-Back Badasses: When they decide to work together, Cure Rouge and Cure Aqua stand back to back.
- Feud Episode: For the third time, the eighth episode is about Rin and Karen fighting with each other.
- Red Oni, Blue Oni: Rin and Karen are literal examples; Rin (Red Oni) is very brash and hotheaded, while Karen (Blue Oni) has a much cooler head, thus their rivalry.
