No clue on that one, but he was likely red as a tomato like all the other true blooded Sith. He was the only Sith lord buried on Korriban to be lord after the discovery of lightsabers.
And to be bloody honest, he was never defeated. Luke, however much he is badass, doesn't have that record. And his competition is much less. While I respect NJO Luke for being an ideal Jedi who can whup ass and take names, he bites the sizzling edge of a saber in this one.
Dude, no he doesn't. If they were to fight Luke would win. Fact is, the force works to destroy evil, and Hord is evil. Take the most powerful Jedi ever and make them fight and Luke will win. But it would probably be like Obi-Wan style. He would have to be extremely resourceful as opposed to just overpowering him.
It's kinda like he inherited that from Obi-Wan...
Okay... So he's liked by the force that doesn't make him all powerful and unless the force actually tells him. "I like you." i'm not inclinded to believe that. Luke wasn't all powerful and he didn't have the experience fighting against Jedi and Sith that Tulak did.
I'm not saying he can't win, i'm saying he is going to have an incredibly hard time and i don't think he will win. Tulak was incredibly good, never lost. Never even got hit. I don't care how good Luke is, he's not going to stand a chance against somebody who has fought countless of Jedi and Sith his entire life.
