we agree on point one
it was a short flashback scene i believe and who knows how he lost, but the point is he lost
again u reference depowered tyrant, not the one used here
who is using god korvac? this is korvac when he killed the collector during the wonderful 'the enemy" storyline
tiamut when he awoke uatu couldn't watch and galactus knew fear...also had enough energies to push the time rip reality warping powers
he put the earth to sleep, sings a song turns back time nearly 14 billion years, faught over 1 trillion horde
he's = to the fulcrum however any wants to perceive that. i have my opinion on that
imo, no one from the two other teams can stop tiamut
i am sure ur opinion b different and that's cool
