Listen to this guys he is still human, he wasnt born the juggernaut he spent most of his life under pain. Its human to make a noise when you get hit no? Like the pillow fight thing. remember just because he cant feel pain doesnt mean he cant feel.
His eyes are still sensitive to light (why the burnning thing night crawler threw in his face hurt). If it was the fire itself then the hot liquid metal deadpool dumped on him would of hurt, or the gas truck spiderman ran into him. The godforce would of hurt him also.
Speaking of which i make my next statement if the godforce did not hurt juggernaut why would a sucker punch to the stomach quote unquote knock him out????????????
He still has a human equilibrium so he gets dizzy and he has human organs he still gets nauseous but he doesnt get sick (you know like throwing up sick) Like in a deadpool comic i have, he drinks tomato juice to keep his stomach in check while he flys (then again it could still be his human instincts or it may just be mental that he thinks he will get sick while flying). So hulk knocking air out of his lungs to make a noise is no big deal, and i wouldnt call it a win.
A win to me is being knocked out or being killed and hulk has never done any of those things to juggernaut. Even hooked on celistial power he couldnt keep him down.
He can distinguish cold from hot but it doesnt affect him. Yet his skin is impenetrable and his bones are unbreakable.
And i think the interview with peter david was either in the back of that comic or on his website. Ill keep looking
