Waverider

Origin

Matthew Ryder was a scientist from the future Earth ruled by Monarch, an armored despot who had eliminated all heroes. Matthew Ryder believed that one of Earth's erstwhile heroes had evolved into Monarch, and, using his scientific skills, Matthew Ryder created a time machine to journey into the past and change history. Matthew Ryder convinced Monarch to let him be a guinea pig in his own device, and Monarch agreed, believing Matthew Ryder, like several initial test subjects, would die in the process. Matthew Ryder however survived, merging with the timestream and transforming into Waverider, a yellow super-powered human being. Traveling back to the past, he joined forces with Earth's Greatest Heroes, including the Justice League of America, the Teen Titans and Captain Atom to defeat Monarch, who was later revealed to be Hank Hall, formerly the hero known as Hawk (resurrected during the Brightest Day Story Arc). Waverider then joined the Linear Men, a group devoted to maintaining the timestream. Although he is not dead, Waverider hasn't been heard of in a long time, he could be hiding anywhere... Waveriders unform has been with a hole in it and being used as clothing.

Powers

Waverider has mastered the art of time-travelling, being a scientist. Due to an accident using his machine, he was turned yellow, and given a golden rod, allowing him to fly and, using the rod, project quantum-powered force blasts. He can access a person's aura and predict the future the most probable for them. 
 

Appearances in Other Media

Waverider appears in the TV Series known as Justice League Unlimited. He is never truly a "spotilighted" character, but more as an object placed in the background, to add more depth to the team. Thus, we cannot discuss if his character remains true to the comics or not.
