Scooby-Doo meets Butch Cassidy and the Sundance Kids - A musical mystery episode!
Scooby-Doo meets Jonny Quest - Could be a continuation of the Cyber Chase saga with Scooby and the Gang and Team Quest in Questworld.
Scooby-Doo meets Pinky and the Brain
Scooby-Doo meets Penelope Pitstop - although this Penelope is the modern-day version of the Wacky Races character, which is her granddaughter
Scooby-Doo meets Krypto the Superdog and Ace the Bat-Hound - Scooby-Doo in his first "World's Funnest" adventure as he assists the Caped Canines against "The Kryptonite Kreature"
Scooby-Doo meets the Legion of Super-Heroes - A time-travel adventure in which a Science Police officer named Fairuza Jones finds herself teaming up with a time-displaced Mystery Inc. and the Legion of Super-Heroes to stop the Time Trapper, who has recruited an army of nightmarish ghouls from the past to prevent the Scooby Gang and the Legion from solving a case that could affect the future of the Blake and Jones families in the 31st Century. And, at the end of the episode, we get to meet the Mystery Five, a group of Science Police rejects who are the descendants of both the Scooby Gang and the Hex Girls!
Scooby-Doo meets Captain Planet and the Planeteers - Yep, the Scooby Gang and the Planeteers team up to stop a radioactive monster! Nuff said!
