On "Prison Break," he was a villain fans absolutely loved to loathe (or maybe even loathed to love), and in "Heroes" he played a diabolical gypsy with a dark agenda. Now, actor Robert Knepper will be playing yet another baddie, this time on Syfy's "Stargate: Universe."

The actor has been confirmed in joining the second season to play Simeon, a member of the Lucian Alliance, sticking around for a seven-episode story arc.

In the premiere episode of "Universe," the Lucian Alliance was the likeliest suspect for the destruction of the Icarus Base after a fleet of Goa'uld motherships dropped out of hyperspace and assaulted the planet. The rogue group was first introduced in Season 9 of "Stargate SG-1" after the fall of the Goa'uld System Lords and the successful Jaffa Rebellion. The Alliance grabbed control of whatever Goa'uld assets it could find, forming a dangerous coalition of the galaxy's most deadly criminals (not to mention a thorn in SG-1's side).
