Hybrid Undertaker from 2004-present has had some GREAT moments, that he couldn't do in the 1990's. The "Hells Gate" finisher being debuted on Smackdown 2008, was just amazing. It felt like a legitimate finisher in an era where risks were being less and less taken. The short "ministry" return angle with JBL, Viscera and Gangrel and where Undertaker sacrificed Orlando Jordan, are pretty good. And of course his legendary return at WrestleMania 20 with Paul Bearer then when he took the hat off, he still had the ABA/Big Evil headband which made it even more epic.
