- Cross-Dressing Voices: Mechazawa-Beta (and Mechazawa when he is rebooted) is voiced by Mika Kanai, Galaxy Angel's Vanilla H, and some Pokémon as Chikorita and Purin (Jigglypuff). She even reprised Mechazawa-Beta's voice in the live action movie!
- Keep Circulating the Tapes: The manga (12 out of 17 volumes) and the anime's DVDs have been out of print ever since ADV Films went bankrupt. Fortunately, Discotek Media re-licensed the anime in 2016. As of this writing, however, the manga is still in limbo.
- No Export for You: The manga was Cut Short in the U.S. five volumes up to its final, right before ADV Films went down.
- Playing Against Type: The director of the anime version, Hiroaki Sakurai, is mostly known for directing cute series like Di Gi Charat, so directing a series starring a bunch of decidedly un-cute delinquents was a radical departure for him. However both series relies on gags and Di Gi Charat sometimes feature un-cute characters.
- Relationship Voice Actor:
- Some of the Japanese voice actors in the cast have shared credits in other series directed by Hiroaki Sakurai, especially in the Di Gi Charat franchise. Besides cameos voiced by Asami Sanada (Dejiko), Megumi Hayashibara (Piyoko), and Miyuki Sawashiro (Puchiko), there's also Ryo Naitou (Takeshi, Paul in Di Gi Charat Nyo) as Takenouchi, Norihisa Mori (Yoshimi, John in Di Gi Charat Nyo) as Hokuto, Yuji Ueda (Abarenbou) as Ishikawa, and Mika Kanai (Kinako Ankoro in Di Gi Charat Nyo) as Mechazawa Beta.
- The English dub cast share a lot of people that were involved in the Gantz dub. It's easy to count who wasn't in Cromartie.
- Stunt Casting: Megumi Hayashibara is Maeda's Mom, if you can believe it. Made even funnier given that Maeda's Mom never speaks a word, only ever doing an irritated moan.
