God I hate MU.com. Their powergrids are so stupid and make no sense. The character you just showed is said to be a reality warper but his official ratings in all categories are 1. I pity anyone who references that site to show someone's power rating. Maybe they should you know redo that whole site.
I think KB is talking about the fact that Cain was written as someone who is only invulnerable with his Forcefield. Apparently if you take his FF away in that book then he is as vulnerable as the next guy.
First the fact that the writer depicted the Juggernauts forcefield as the source of his invulnerabilty.
Second the writer also made it seem that Thor severed Juggernaut from his power source, which we all know would've turned him back into Cain and the beating Thor gave him would've killed him.
Third it turned out to be all for naught. Despite seemingly taking away Juggernauts power and many peoples assessment that Thor gave Juggernaut the beating of a life time, Thor failed to even knock him off his feet. When the 60 seconds were over Juggernaut resumed handing Thor his ass before Thor BFR'd him.
well that too, even Thor was amazed at his durability. I mean I know that magic of sufficient strength can hurt cain but Thor's fists aren't that magic.
