One of the iconic heroes in comic book history has to be the stretch sleuth known as Plastic Man, created by legendary writer Jack Cole. And from his initial 1941 appearance in Police Comics #1 through that series' conclusion and that of his own title published during that decade, the former Eel O'Brien became a legend. And a desired property for other publishers, particularly DC Comics which acquired the Quality Comics character.
So in 1966 Plas was reintroduced, or rather it turned out to be his son. Then, the original turned up in a couple of early 1970's Brave and the Bold issues teaming up with Batman. But was this the original? And what became of his son? Well after his own revitalized mid-70's series had concluded, he had a string of Adventure/Super Friends/Worlds Finest Comics solo tales. Intermixed, he was affiliated with at least three teams of champions of three Earths!
During the Convergence event that pulled various cities and their heroes to a planet outside space and time, Plastic Man along with you fellow Freedom Fighter battled the Nazi villain Silver Ghost. During the conflict, Plas and the Ghost formed an uneasy alliance to track down the origin of deadly cyborgs threatening the citizens of their displaced New York City. After a final battle when the Ghost betrayed his foe turned ally, Plastic Man was left outside and separated from the Fighters. Where this version of the hero ended up in the multitude of cities on Telos is hinted at in an encounter Plas would have with Kid Eternity. He didn't return to Earth-Two, as the Senate hearing that tried the Justice Society in the 1980's said that Plastic Man disappeared in the 1940's. In fact, near the Earth-X New York City on Telos which he had just left behind was the Earth-One Gotham City from the 1960's. When that city returned to its native universe, Eel migrated there and made it his third home world.
