Gangrel maybe, although it didn't carry him any farther than a European Title shot. He had that awesome music, the entrance with flames, the blood-spitting, his own stable, and the bloodbath routine, and people seemed into it. I can't remember anything that he did, though. He had no memorable matches (maybe a product of the time), and I don't know if he ever got to cut a promo.
Anyway, he wasn't carried very far by his gimmick, but he strikes me as a guy who was over solely because of the gimmick he was given rather than because of anything that he did.
Someone (And I think it's Christian) tells a story about how they had HUGE plans for Gangrel. They loved the entrance and the look and everything else, but the first time he had a chance to do a major promo, he froze and that was the end of their faith in him.
I think Edge says something like that in his book.
