Time travel is real, and all of history is vulnerable to attack. But one group travels throughout time to stop the spread of these so-called 'Time Aberrations' and erase their damage to history. A group of outcasts and misfits, they are no longer saving the world. they are saving history. But these individuals aren't heroes, they're something else.
Pandora’s box; an object that exists outside of time and space, capable of allowing true evil to enter Earth’s realm. If opened, unimaginable horrors of unknown quantities and capacities will enter the world, enslaving it, bringing it to its knees before turning it completely to ash. In the year 2268, the timeline was altered and someone opened Pandora’s Box.
Sensing the change in the timeline, a being from outside of time itself, the android assistent to the New God Metron, the Hourman of the 853rd Century, reached out to a rogue by the name of Matthew Ryder. A time traveler, Ryder and his crew took the fight through time but were sorely defeated with only Ryder escaping before his ship, the Waverider, crash landed in the 21st Century.
With his reality now gone, Captain Ryder and his timeship, the Waverider recruited a new team. This team couldn’t just be anyone however, even with the prime choices available in the Golden Age of Heroes. Contacting the Justice League or even the Teen Titans would have been the most logical choice, but Ryder knew the roles of each and every member and the parts they had to play in the still unfolding present.
Instead, this team had to be made up of individuals with no notable bearing on the timeline. Assembling a crew of outcasts and misfits from throughout time to combat the impending doom, Ryder tasked the crew with what seemed like the impossible, revert the timeline and stop Pandora’s Box from being opened. Although these recruits are had no effect on the world in their own times, if they manage to help Ryder, they’ll be more than heroes.
They'll be Legends.
