X1

Once a hero for the Galactic Republic, X1 later became a threat to the galaxy after embracing to the Imperial creed and the teachings of the Sith. After the Emperor's death, X1 set up his base in Darth Vader's abandoned personal castle, even going so far as to use the Dark Lords prized possessions for his own personal conquest for the Sith against the Rebel Alliance. When X2's Jedi training was completed under the tutelage of Jedi General Rahm Kota, X2 hunted down his brother on Mustafar and killed him by pushing him into the lava.

He is one of the six heroes who doesn't ever appear in any canon media.
