From what I understand...Juggernaut is only unstoppable when he is moving forward. I don't think that applies when he is just standing still. In this post...Juggy is just standing there...so, i think any version of him is gonna get knocked back...or atleast moved. I'm not sure about all of that about Juggernaut anyway. He is supposed to be unstoppable when moving...but, i bet a full powered Galactus could kick him in the chest and punt him out of the atmosphere like a football..lol
