The Mystery Machine

Fred Jones' vehicle employed by Mystery Inc. to traverse the country solving mysteries, before Fred came to use the Misery Machine instead.

Description
The Mystery Machine is Mystery Incorporated's signature vehicle that they use to travel across the USA (and sometimes different countries), and if need be, as shelter/base of operations when solving mysteries in various localities.

Fred vehemently claims the Mystery Machine becoming the Misery Machine is a result of a series of events resulting from a few his traps meeting with failure.

History
The van was previously owned by one of those family bands known as the "Mystery Kids", and allegedly acquired by Fred shortly it disbanded due to drama (as they always do).

Fred Jones, Shaggy Rogers, Daphne Blake, Velma Dinkley, and their mascot Scooby-Doo use it to leave Coolsville and travel while solving mysteries during their summer break.

When Shaggy, Daphne, and the cursed one go on journalistic adventures, Fred lends the van to them.

TFR/Season 1
Fred was so utterly disgusted by Scooby-Doo's new "accomplice" that he gifted the Mystery Machine to Shaggy, and when Mystery Inc. disbanded, refused to acknowledge ever again. He got a different van eventually which he would end transforming into the Misery Machine.

Match History
At some point the Mystery Machine may have gotten possessed by a poltergeist.
