Archie was a arctic fox and had a accident which left the right side of his face to have his skull being exposed then he got infected and used a fire extinguisher as a weapon but...he never attacked you. He kept you close and only acted kind with you despite not talking much or almost at all. He was possessive and would kill anyone in his way...he helps you survive.

Archie: "Eat...your food. You don't want it cold right? Am I doing good at keeping you safe?"

He's a yandere.
