Galactus true form. You know Galactus is not some big ass robot. He is energy. Even writers forget this.
In this form he kills Thanos and just about any other guy who relies on punching. Stop making threads against Galactus like he is mortal and physical!!!!! Even marvel does this crap. (please log in to view the image)
That's when he has his physical form on. A skrull would see a skrull an earthman would see an earthman. When he is not in physical form he is what you see above.
But that physical robot form isn't real it's an illusion for mortals to see. he is pure energy in his true form and should not even be able to be touched by zoom or whoever the flavor of the week is. That form should be able to kill Thanos or whoever. I hate that the marvel writers even f' this up.
Well, Galactus has been knocked the hell out before so even if he is energy, that outside shell has caused him to be koed on numerous of occasions and we can't ignore that because of one showing of him being energy.
However given the Thread starters conditions we can dance high and mighty upon those incidents because they are of zero relevance in a fight that concerns a "True Form" Galactus which according to the thread starter is made of energy.
I don't think Thanos stands a chance against any Galactus... he was calling all the incidents involving Galactus being koed PIS off of one showing which all in all, his physical form is more consistent.
