Fourthwalling: ✘ [ this is fine in memes or if the character ICly breaks the 4th wall ]
Threadhopping: ✔
IC
Physical Contact: ✔Mental Contact: ✔ [As per the book, an angelic or demonic mind isn't profoundly different from a human's. They aren't necessarily more intelligent, or possess eldritch depths. Their intelligence is just broader in scope, with the advantage of thousands of years of practice. So no worries about him short-circuiting any psychic minds. Though if he recognizes that someone is rummaging around in his head without permission, he will absolutely retaliate by thinking of the most annoying song on constant loop. Enjoy your earworm. ]
Fighting: ✔
Injury: ✔
Kidnapping/Imprisonment: ✔ [The average cell won't hold him, but a half-competent occultist with a piece of chalk and a passable knowledge of sigils and magic circles could keep him reasonably contained. Crowley is not a big-time demon.]
Death: ✘ [Discorporating him is fine though!]
SHIPPING
Flirting/Affection: ✔ [Crowley is all about temptation, but don't expect anything beyond flirtation/]Hugging this Character: ✔ [He may even hug back.]
Kissing this Character: ✔ [Don't expect reciprocation unless your name is Aziraphale.]
Romances: ✔ [Not impossible, but again, highly unlikely. Crowley has been pining after one (!) angel for a few thousand years. It'd take a lot to turn his head - and even then brace yourself for the slowest of slow burns.]
