Johnny "sticks things in his mouth cute nomnom nibble variety" MacTavish who is always nibbling on something: pen, hoodie string, Gaz bicep, Ghost shoulder, gum, ice, straw. Just a constant need to nibble and crunch. No immediate danger, just nibbly little guy. Gaz is covered in small scars from where Johnny's sharper canines had got him. Doesn't mind at all. Ghost is constantly walking around with little bruises. Doesn't mind at all.

Simon "jaw of an alligator, danger danger big chomps !!!" Riley who chomps anything that comes too close to his face. Not a biter necessarily, doesn't need to fill the urge like Johnny does. But once something is in his mouth he is not letting go, it's his now, thanks. Of course, this only works when his mask his off, so often it does end up being the meaty part of Johnny's hand or Kyle's shoulder. Kyle is the perfect height for it, Simon can rest his shoulder there, and if the urge so prompts him just open his mouth and sink his teeth down.

Kyle "pressure seeker" Garrick who needs desperately to have weight on him otherwise he will not, under any circumstances, chill the fuck out. He's wired for movement and progress and solving problems. So when Johnny's teeth find him it's normally accompanied with the Scot piled on him, boneless and content. And now even just Johnny's bites on his hand are enough to steady him. And Simon's solid, firm, almost painful bites are enough to pull Kyle back to reality and away from anxiety.
