Okay Silver age Mangog was strong but did anybody remember Silver age Surtur? The same one who's finger alone almost killed Odin so Odin had to bring metetors across space to hit them? The same Surtur who destroyed two entire galaxies one being Beta Ray bills? The same surtur who cuts open rifts with his sword, who's killed the original odin brother which created the odin force and knocked out Odin while odin was at the door of his dimension and he wasn't even there? This guy is over 1000ft tall and probably just as strong as Mangog, he is above the Odin force with the sword in his hand last I remember. Mangog will put up a fight don't get me wrong but this is surtur he has an entire dimension full of demons as an army to command and if he doesn't want to do that he can just do it himself. Anybody saying Mangog wins can they even say how he wins or just saying he wins?
