Cast members are Toons whose existence is canon in the storyline of Toontown Rewritten. This not only includes certain NPCs like Flippy and Doctor Surlee, but also members of the Toontown Rewritten Team.
Any staff member who appears in-game with a blue staff icon is considered a "cast member", as shown in the image on the right. Before replaced with a blue icon, there used to be a yellow and green icon, which represents Toon Troopers and Resistance Rangers. However, not all members of the TTR Team have a cast member Toon. Several of the staff members haven't written their own blog posts on ToontownRewritten.com, but were referenced in some.
- Slate, one of the texture artists, was given the opportunity to be a cast member, but she chose not to according to her YouTube channel's FAQ.
