4th WALL BREAKING: Original character over here. But I'll ask you not to identify his PB (Colin Firth), just to think they're very similar.
THREADJACKING: Stick to the strictly necessary and keep it short, please.
BACK THREADING: Always and forever.
MIND READING: Yes. They can sense there's a second entity in his mind.
LOCATION SENSING: Yes.
TELEPATHY: Yes.
SPECIAL/MAGICAL ITEMS: Yes.
FIGHTING CAPABILITIES: Jack himself is a bit useless, but if Cerbos takes over he will be quite capable of defending himself and causing considerable damage. There's enhanced senses, super strength and speed to consider (and monster teeth).
INJURY/DEATH: Perfectly willing to plot something out, just talk to me first.
WIN/LOSE/TIE: Same as above.
MEDICAL/PHYSICAL INFO: Because Jack is inhabited by a monster, his insides have been rearranged with fake and corrosive organs. His body is capable of curing several kinds of injuries. Illnesses might work differently (or not at all) on him. It's only important to feed the monster (with other people) so Jack himself doesn't need to eat anymore. And because Jack is only alive because Cerbos took over his body, if Cerbos were ever to leave or be forced out of it, Jack would face certain death.
ROMANCE/RELATIONSHIPS: A very tough challenge, but not completely out of the question.
SEXUAL RELATIONS: Out of the question, for obvious reasons.
PHYSICAL CONTACT: Jack abhors it and Cerbos doesn't mind.
ANY TRIGGERS/SECRETS/FACTS YOU WANT PEOPLE TO KNOW ABOUT: Cannibalism and extreme violence... But it isn't something I'll just bring up left and right. Still, if you have a problem with it, let me know.
