- Nega-Chin is the Crimson Chin's evil counterpart, much like Nega Timmy is to Timmy Turner, or the Anti-Fairies to Fairies.
- He is a possible parody of Bizarro and Venom (of course before Venom became an anti-hero).
- According to the infocard seen on this site, he only flosses right before going to the dentist.
- Nega-Chin's name and Mr. Crocker's pronunciation of it got Nega-Chin into REALLY big trouble, since it sounded very much like another, very dirty word that was similar.
