The Marvel character who basically created the whole of time and space, including all realities and dimensions? He was in Dr Strange in the 70s, if I remember....
Isn't he more powerful than both Tribunal and Eternity?
He's always forgotten in these type contests...but I remembered there was SOMEONE above Tribunal.
So in a top ten, it's probably going to go:
1. One Above All
2. Living Tribunal
3. Cosmic Abstracts like Eternity, The Brothers, Death etc
4. The DC GOD (creator of the Multiverse, Spectre's boss)
5. Galactus
6. Imperiex
7. The Anti Monitor
8. Thanos
9. The Spectre
10. Classic Darksied (not the new pu$$y-fied one)
I'm thinking the Presence, the DC God, should be number 2 in this list on reflection.
