Tropes associated with Diomedea:
- Animation Bump: The Japanese opening for Transformers Animated, which utilized some help outside the companynote .
- Harem Genre: The bulk of their (non-subcontracting) library as of late.
- Limited Animation: One of the worst offenders in recent years, generally compared to either Studio DEEN, Magic Bus or the worst of Toei Animation.
- Production Posse: Has used Asahi Production and Studio Jack in several of their works.
