i believe that onslaught is more powerful than galctus. big aint too big in the marvel universe these days, onslaught{as he died} could probably take on onslaught.
How are you gonna try and say that the power of Magneto, Prof X and Nate is enough to take on Galactus? Dont be silly. Onslaught would only stand a chance if he mastered Franklins abilities but he never did. He wasnt around long enough.
Onslaught would have had trouble taking out Thanos. Thanos recently handled the cube being Kosmos(the Beyonder).
Not because he was more powerful but because of his skills with using his powers. The cube beings are well above the likes of King Thor, Zeus etc. Any of them would slaughter Onslaught.
Thanos is no match for Galactus and he said this and had to flee from a recent battle with him. Galactus would murder Onslaught.
Onslaught, in acknowledgement of what power he displayed and what he did to earth and its heros, was definitley MORE than the summ of his parts and would certainly stand a chance at least against a Galactus written in a weaker form(done a lot lately).

i disagree armandovalles, onslaughts ARMOUR{not even a fraction of his power} withstood direct attacks from mlijnnor without even a dent, id definately put him a LOT higher than thanos, and even mindless hulk, posessed of infinte strength could only rip apart that armour, but then what happened? ONSLAUGHT ONLY GREW STRONGER, and the hulk was seperated form bruce banner in the following explosion{THINK ABOUT THAT, "MINDLESS" HULK WAS SEPERATED FROM BRUCE BANNER}, the whole of marvel earth couldnt stop him, hes a lot more powerful than most people realize, he could create a second sun for heaven's sake and when he fell, MANY UBER POWERFUL HEROES {like thor} HAD TO SACRIFICE THEIR ENTIRE POWER AND LIFEFORCE TO "UPSET"{not destroy} HIS ENERGY FLOW WHICH CAUSED A REACTION RESULTING IN ONSLAUGHT'S SELF ANNIHLATION.
Onslaught wouldnt defeat Galactus really He only tore the Ruby Of Cyttorack out of Juggernaut not even Dr Strange could do that by His own admission Galactus cant even break the Crimson Bands Of Cyttorack witch are what power Juggernaut if you ever read the spell Juggernaut said when He first became Juggernaut it speaks specificly about gaining the power of The Crimon Bands Of Cyttorack
And how do any of you know He hadnt mastered the powers of Franklin Richards i mean He did create a second sun and He was only defeated after His armor was destroyed even then He just evolved and it took all the Hero's jumping into Him to destroy Him.
