Kane (C&C)

The first murderer
Kane is the charismatic, absolute leader of the Brotherhood of Nod, who features prominently in all of the Tiberium Universe games, as well as in the original Red Alert game as the secretive advisor to Joseph Stalin.

The Slow Rumble
Kane came to the slow rumble to conquer it after hearing that a great concentration of Tiberium was found under the arena.

Also he might have some connection to an old TFR veteran, Joseph Stalin.
