Matches (voiced by Frank Welker) is the dragon character from Scooby-Doo and the Ghoul School. He is Miss Grimwood's pet dragon.
He wasn't fond of Scooby at first (since he laughed at him), but he later warmed up to him. He also became friends with Scrappy Doo. When Matches gets angry, he glows red, then breathes out fire like most dragons. He can also get a little feisty around strangers, but once they get to know him, he's fine. Matches also hates being left out.
- Matches will join Hiccup's team with The Grimwood Girls.
