Nicol Bolas

He created the planes of Amonkhet and Ixalan. Master of the Realm of Meditation. Slayer of Ugin. Pre-Mending planeswalker. One of the three great Dragoddsnlords.

As arguably one of the strongest planeswalkers to ever exist, Bolas is often at the center any nefarious actions that occur within the Multiverse. Bolas took on Jace Belaren as an apprentice for a while. He also let in The Hero into the multiverse. It is rumored that Bolas has a unique means to consume the sparks of other planeswalkers.
