The Nerevarine was able to defeat both Dagoth Ur and Almalexia, both of whom were considered immortal until he cut them down. In the process, he also prevented what would've been a Dragon Break by stopping Dagoth Ur from activating the second Numidium. Finally, he is one of the few beings in Mundus to ever interact with the Heart of Lorkhan, and I feel that holds some significance.
