Ricky Owens

Ricky Owens was one of the missing original Mystery Incorporated members who allegedly disappeared in the Crystal Cove Caves. He returned under the alias of Mr. E having built a seedy corporation called Destroido Corp.
The original Mystery Inc.'s Ricky is the older counterpart of the younger Mystery Inc.'s Shaggy Rogers due to their respective appearance and personality, as well as their friendships with their team's mascots, Professor Pericles and Scooby-Doo.

He also shared a (somewhat) similar relationship with Cassidy Williams to the one shared between Shaggy and Velma Dinkley. Cassidy was attracted to Ricky, and the latter couple were briefly in a romantic relationship. Ricky, Cassidy, and Pericles also paired off like Shaggy, Velma, and Scooby, respectively, when looking for clues.
