Pinhead has supernatural power. Only time he was physically affected in any way that i can remember was when doctor channard beat him (easily), but i don't think that really counts. channard also had the power of hell at his command, and pinhead was vulnerable to his attack because he was having an existential crisis. if he was still committed to doing hell's bidding, i believe he would have put up a real fight...but thats a paradox of course, because in that case he would have just accepted his place as channard's #2
i always considered it a huge inconsistency that his chains continued to work after he did that face turn, but i guess they needed to show the chains being cut. cinematic at the expense of reason
anyway, i think this topic is a setup for "no limits" fallacy used by pinhead's side. pinhead (when focused on being hell's bounty hunter) was always perfectly equipped to conjure up something from nothing in order to subdue or kill anyone/everyone. he never physically did anything but talk shit and nod his head to throw chains or make some other f*cked up shit happen. there's no way of debating for or against him having the power to subdue zod. the possibility exists, but it cant be asserted.
