Originally posted by UtrigitaTyrant said that he wouldnt benefit from a battle at this point. Galactus asked for one thing his herald,Morg. Tyrant stared him in the eyes and said he wants Morg. Galactus gave in even though he only wanted Morg but Tyrant got him. To me thats backing down. It was in neither of their best interests for an all out battle then so the both agreed on that they would indeed finish it later. Galactus knew from that moment on he would have to deal with Tyrant and planned poorly for it.
Lets assume instead that both have learned from there second encounter. which is the most likely event to have happen.A Galactus that was badly prep in comparison to Tyrant Galactus never thought he would see Tyrant again showed in Tenebrous scans, Tyrant was backing just as much down as Galactus was in the scans posted by Tenebrous, at that Point even Though Galactus was weak Tyrant wasn't interested in a Conflict even though he claimed he was on his highest level of power since his depowerment. This IMO all speaks for Tyrant in some way counting on Galactus using his tech against Tyrant in some fashion so that Tyrant could bend that Technology to his will. And both knew as the scans also show that the winner if they fought now would be the one that was most powerfuln but such a battle would cause untold destruction hence both where not insterested in it.
In the third conflict it would indeed be different but as far as I see it Galactus' blasts could still power him up. One thing is for sure it would be one helluva a destructive battle. I think Odin and Thanos tip the scales definitely in their teams favor.
