While it might seem that characters with endlessly elastic bodies are incredibly common, Plastic Man is probably the first. He's an incredibly long-running character, dating back all the way to Quality Comics in the early forties. While many modern characters seem to use similar powers (like Elongated Man, Mr. Fantastic, Ms. Marvel, and Elasti-Girl of both the Doom Patrol and the Incredibles), Plastic Man is by far the purest take on the concept. He's a cartoon personified. While this was a fairly straightforward concept when it was introduced back in the 40's, for a character to be able to exist with such a meta concept and still be seen as a viable Superhero alongside the other tentpole characters in the Justice League is a real feat. Given the fact that his modern appearances happened largely because of Grant Morrison's inclusion of the character in his Justice League, that shouldn't be too much of a surprise.
Because the character is meant to have been a holdover character from an earlier era with a long career, we decided to make him a part of the All-Star Squadron. Also, inasmuch as he only appeared occasionally, we've deliberately had him retire once his career with the Squadron is over. His son Luke is going to be an important part of the story going forward as one of the teammates of Damian Wayne on some future version of the Teen Titans, so we've been careful to make sure that Eel dedicates himself to raising his son.
