Here is a first attempt of mine of Captain Hook, let alone a truly terrifying one who was voiced by none other than Tim Curry in the Fox Kids version of Peter Pan (he won a Daytime Emmy Award for his performance in 1991). I'll have to remind you a couple of things in regards to my model of Hook:
Being able to have his hook attached to his amputated right hand can be a hit or miss (because the hook either may not look correct or may for some reason be carried with his hand or the hook is on the wrong hand), though I find that strengthening these trigger words amputated right hand, right hand hook and maybe adding left hand hook as a negative tag can help relief the risks of incorrect and inaccurate generation, though it's not a 100% guarantee.
There are issues with having Hook carry his sword with his left hand as he does in the cartoon including the issue of him carrying more than one sword. Maybe this negative tag multiple swords can help.
Try using ADetailer so Captain Hook's face can be generated nicely at a distance.
In the episode "Demise of Hook", at times, he wears a scary white mask to intimidate and scare the Lost Boys and the Darlings after faking his death. To have Hook wear the mask, use the tag scary white mask in place of his black eyes tag that is in the description.
Other than these issues, enjoy!
