On which existing work is Legends of Tomorrow based?
From the trailers of Legends of Tomorrow, Rip Hunter (time traveler) gathers a team of heroes and villains to fight with Vandal Savage. And he refers to them as legends rather than heroes. I wonder what existing DC comic it's based on. I don't know any team with this kind of roster. Or is it an original work?
Note: Legend is Tomorrow is an upcoming continuation work of Arrow and The Flash.
I don't know of a team in the comics with that particular ensemble (Firestorm, The Atom, White Canary, Rip Hunter, Hawkgirl, Heatwave, and Captain Cold). It looks like an original work based on characters that were already introduced in the CW's other shows, Flash and Arrow, with the exception of Rip Hunter, who is a new character to TV. The concept looks similar to several stories involving Rip Hunter in the comics, where he assembles teams of heroes (or works with existing teams) from different time periods to work on one mission.
