Matthew Ryder

Matthew Ryder is a fictional scientist and time traveler, and a recurring character featured in titles published by DC Comics. Because of the vagaries of time travel, as well the publisher's penchant for rebooting their continuity once a decade or so, there have been multiple versions of Matthew Ryder, who is also known by the code name Waverider. Waverider was introduced in the first issue of the Armageddon 2001 comic book limited series in [[1991. An alternate version of the character was introduced in Superman, Volume 2 #59, also in 1991.
