Jack has pretty much zero magical/supernatural abilities.  Aside from him having his face stapled onto... his face, he's got nada.  Usually he depends on the use of digistruct technology and his gigantor robot army to help cover his ass but he's distinctly lacking in both of those departments here!   Unless he ends up regaining anything later, you're golden for now.

HOOOOwwwever, Jack can be extremely crude and douchey.  He will have absolutely zero qualms with picking on your character and doing everything in his power to make them feel like a piece of shit.  About 50% of the time it will be on the level of a 10 year old child and the other 50% of the time will just be outright offensive.  There are no restrictions, no boundaries.  Men, women, children, and robots alike are all subjected to this kind of treatment.

THAT SAID, if you'd like to opt out of this kind of interaction, I entirely understand and will by no means take offense.  Just let me know here!
