4. The Living Tribunal - Since The Dawn Of Time

The Living Tribunal was, for a long period of time, considered the highest power in the Marvel Universe. He presides over and judges the multiverse accordingly, with Stephen Strange's earlier tests as the Sorcerer Supreme actually involving him having to convince the entity that the Earth is worth serving, despite calls to the contrary.

He's a big deal, and has come to be one of the few constants within the cosmic vestiges of the Marvel Universe. His power levels are also off the charts, with the character having been considered the most powerful in the universe prior to the introduction of Marvel's own equivalent of God who, as the creator of the universe, is the oldest being in existence.

In any case, mainstream audiences should probably see the Living Tribunal at some point. The character was name-dropped by Mordo in Doctor Strange, and with the next phase heading down a distinctly more cosmic path than others, an appearance in either Doctor Strange 2 or a future Avengers shouldn't be ruled out just yet.
