The Living Tribunal is a vastly powerful humanoid cosmic entity in the Marvel Universe who has existed as long as the universe itself. Its function is to safeguard the multiverse from an imbalance of mystical forces. It may act to prevent one universe from amassing more power than any of the others, or from upsetting the cosmic balance in some way. The Tribunal may also act to prevent an overwhelming imbalance of good or evil within a universe.
He is considered to be an omnipotent entity, being more powerful than Eternity and Infinity. His power is such that he can nullify the power of the Infinity Gems in unison. He is only surpassed by the Beyonders and the One-Above-All.
