Tall! Remus! He's just taller than average doorframes so he bashes his head a lot and when he does he either lets out a long string of curses in Spanglish or just- 'mierda.'

Janus goes up to random sides and takes their wrists and makes them hug him. Often with the phrases: 'huh me bitch' or 'I'm a touch starved snek give me attention'

Short Virgil sits on top of slightly open doors and jumps onto whoever's coming through's head (usually roman) it's taken practice to perfect (ask Janus, he has much experience)
Once Logan dodged and virfil got concussion

Patton has a ton of bracelets and anklets, one for each side and then rainbow ones on top of that

Ballet👏roman👏

Logan has three pairs of glasses: normal everyday, reading, and blue light ones (tinted a warmer colour for when he's using electronics)

Roman and Virgil both have lots of tattoos, they each have a tattoo of their symbol thing

Virgil has a septum piercing

I can't write quick enough so have a screenshot

Virgil has like 7 rings

Logan says he has no tattoos other than the brain one but has like four

Pattons tattoo is on the inside of his left pointer finger

Virgil got a semicolon tattoo (;) after AA on his left wrist

Remus has a tattoo of a rat on his ass

Patton has millions of these

He keeps them in a box that used to hold dishwasher tablets and kept the smell because that's my childhood nostalgia coming through

Preschool Teacher au Patton gives the silly bands to good students

Virgil has fangs. That's it. That's the headcanon

I know I just published it but- Virgil sitting on a door, ready to jump when there's a small bang causing him to nearly fall off the door followed by a long string of Spanglish curses

PETS!
These are the ones in most of my aus I think

Janus: boa names Ellie, usually one or two other snakes

Virgil: tarantula named Charlotte
