Trigon
vs
Dormammu
Last time this came up it seemed Dormammu got the nod due to having more feats, Trigon tends to be a lot of mouth with no trousers.
Honestly all I know is he is a demon and Raven’s dad.
Furnace face is the master of countless dimensions into his dark realm, so strong classic Strange could not over power and is supposedly in the Sky Father bracket.
Trig in got nothing on that from what little I have actually seen.
