Some of the weaker ones like Sin and Titania can and would be taken down. The second tier Worthy like Gargoyle, Attuma and Angrir would beat almost every League member not named Superman but team work and such would be helpful. The more powerful ones like Nul, Kuurth, and Absorbing Man? I just don't know if the Justice League, even with the number advantage has the capabilities to put them down. I think you'd need a lot of the resources just to take down those three much less them and the others.
Martian Manhunters telepathy would usually sway me but that's a no-go with the Worthy's protection. Assuming the Grey Gargoyle's stone stare is allowed, it can also potentially eliminate a huge chunk of the Justice League.
For once in your DC fanboy life provide something to prove that the new versions of the DC characters (with their major lack of high end feats for the most part) can keep up with the established versions of Marvel characters?
Judging by feats DCnU Superman wouldn't come even close to beating Thor, but DC fanboys believe that to be, even though Thor's feats are massivly better.
As I said it ... this is all about if Flash can use his speed force to remove Kuurth from the battle. If not Kuurth solos, since he was without a doubt the most impressive Worthy and no one was able to stop him properly.
Like what exactly? I've seen his Motherbox open up a boomtube but even that is hardly practical for a bfr attempt. Even self-bfr is difficult through a boom tube apparently.
Hal can easily counter most of the offense from the Worthy?
Actually, the Worthy can fly and teleport not only across distances but IIRC dimensions. A Worthy's hammer seems to have the standard enchantments of Mjolnir such as energy projection, weather manipulation, teleportation, flight along with amping individual characteristics. It was explained IIRC that the more ground based bricks (Nul, Angrir, Kuurth etc.) prefer to use their usual method of transportation due to instinct but as we saw, they can in fact use other powers when necessary.
