Challengers of the Unknown (alternate series)

Challengers of the Unknown is the title of a comic book series used on various occasions by DC Comics. Most of these series dealt with the original Challengers of the Unknown. The concept behind this team was a group of individuals surviving a disaster (a plane crash with the original group) and deciding to collectively do something with the "borrowed time" they had left.

On two occasions DC used the name and concept, with a new set of characters, as the basis for a new series. The first of these two, an ongoing series that was part of the Weirdoverse line, was published from late 1996 to mid-1998. The second was a six-issue limited series published in 2004.
