The Joker was released in the 1974 wave of "Super Foes", with the exception of one character, all of the Foes were Batman Villains.
The Joker shows that Mego had made some advancements in the silk screening process, his outfit consists of a drawn on suit complete with removable jacket and shoes. This colorful character was an "Home run" for Mego as it captured the clown prince of crime perfectly
Despite his being in the offering from 1974 to 1981, the Joker is most commonly found on a type 1 body.
There are is some variation in the material used on the Joker jacket.

To this date, no evidence has been found for a Lily Ledy Joker, it is not mentioned in any of their sales material nor has anything surfaced in the market. This is puzzling considering Joker's importance and popularity, and the fact that lesser characters received the Ledy treatment. Given the find of a Green Lantern Ledy head, many still hold out hope that the Joker will be found hiding out South of the US Border.
Joker was the only Mego Villain to get his own wheels.
