"Chazz!!" is a yonkoma, which appeared at the end of the third chapter of the Yu-Gi-Oh! GX manga.
- One night there was a meeting about Chazz Princeton at a fancy restaurant near the office.
- To Naoyuki Kageyama's surprise, Kazuki Takahashi allows him to change characters' personalities for the Yu-Gi-Oh! GX manga.
- As Takahashi sips at his wine, he suggests that they make Chazz a cool guy and give him new cards.
- Kageyama breaths a sigh of relief, thinking that he couldn't do a wacky character like the anime version.
