Marvel has some of the weakest characters in all of fiction in comparison to DC, Darkhorse, Valiant, Image, and Anime. Marvel weighs in at about 3rd on the list, but make no mistake, Marvel characters at the high end are far less powerful than DC characters. It’s nearly like comparing a flea to an Elephant.
I remember Aquaman making a similar statement about the power difference between the Marvel characters and DC characters on average, I remember the statement offended Captain America.
I wasn't really talking about that list, which is wrong. More to the tune of no average Herald to High Herald level character in Marvel would be able to defeat a Darkseid Avatar In physical battle. They'd all be erased, and if not, they'd have a large chance of being telepathically subdued. The Green Scar was not a High Herald, but the Omega beams would likely make short work of him all the same. Cosmic King Thor is also far from being a Herald level character. It just goes to that instances like these are far removed from the norm. In other words; not on average.
