Mr. E

Mr. E
Mr. E is an anonymous person who assists the Mystery Inc. gang is their mysteries.

Origin
At the end of Beware the Beast from Below he called K-ghoul and said that they shouldn't have brought back the locket that Daphne Blake found in the sewers and that the real mystery has just begun. Then in The Creeping Creatures he sends the gang to Gatorsburg and replaces their stolen engine. In The Secret of the Ghost Rig he gave them a CD that helped them solve the case. When Daphne was kidnapped by the Man-crab in Revenge of the Man-Crab, Mr. E provided an 8-Track casette and an artcle talking about other people disappearing, meaning the kidnappings have had happened before. However, The Song of Mystery is the only episode where Mr. E wasn't mentioned or heard. On the episode, Legend of Alice May, he also provided an old year book, book marked on a page about ORGINAL Mystery Inc..
