Insert details here.
Scooby-Doo! (DC Comics)
He was hired by Mrs. Swords to give a one-time appearance at a concert given by Pritty Swords, to add some extra excitement. Pritty didn't know this was going to happen. When he used a powerful vacuum from his craft on her, it pulled off the fake plastic tiara she was wearing. When he realized he could be blamed for stealing the real tiara, he gave the fake one back to the gang to help them solve the mystery.
- Even though he acted as a hired performer, he is left sufficiently mysterious, making the possibility that he might be a real alien left open.
