#3 The Undertaker
Speaking of The Deadman, to me, he was always Mr Smackdown.
Having initially been picked first for RAW in the inaugural draft, The Undertaker would soon find his way to Smackdown just a few months later.

He would go on to stay there until his part-time schedule kicked in early 2011. That's around eight and a half years of his distinguished career spent on the Blue Brand.
Now, despite its status to many as the roster which had the best wrestling quality, many a fan would still class SmackDown as the B brand. As a result of that, you would expect a Superstar of The Undertaker's stature to simply request a move if he wanted a better spotlight.
But no, he remained on SmackDown throughout, unlike the others on the list who have flipflopped between both shows.
On top of never moving to RAW though, he spent a lot of these years putting new, up-and-coming talent over. So not only was he defining his legacy, but he was shaping that of others.
He made Great Khali look great on his initial debut. He helped Edge look like a credible threat in his early championship days, solidifying the Ultimate Opportunist gimmick.
