Tarkin was one of the villain of the original Star Wars, even bossing the big, bad Darth Vader around. A younger Tarkin appeared in Star Wars: The Clone Wars, but the first image of Tarkin in Star Wars Rebels (via EW) reveals a Tarkin that looks closer to Peter Cushing's on-screen appearance.
Tarkin will appear in the February 9 episode of Star Wars Rebels, "Call to Action," with Stephen Stanton reprising his voice role from The Clone Wars.

Star Wars Rebels airs Monday nights on Disney XD.
