1. He's not scared of much, but one of his greatest fears is being completely alone. Despite how poorly he treats most of his friends, he needs their company to stay sane. The longer he spends alone, the more volatile, short-tempered and prone to violence he becomes.

2. He can't swim very well. This is partly because he never learned how to swim properly, and partly because his wings become heavier when waterlogged, dragging him down.

3. His thin pupils are said to be a sign of evil intentions in crowdragon mythology. This is not true, as many good-hearted crowdragons also have slitted pupils, but the myth does suit Crowley.

(TBC...)

4. Has a mild liking for cliched, edgy horror stories/creepypastas. Sometimes spends his nights reading up creepy fake stories on the internet. He finds most of them forgettable, but somehow keeps getting sucked in.

5. Canonically, he doesn't have a home, at least not in the physical realm. Having the ability to walk through the dreamscape, he sometimes hangs out there in a dream realm he created for himself. In the Shacklestone AU, he lives in a cheap apartment.

6. The angular, jagged handwriting I use on some pictures, especially the ones involving him, is supposed to be similar to his own writing.

(TBC...)

7. He enjoys Christmas, though he'll usually deny it so people don't think he has a 'soft' side. He likes the festive atmosphere, the decorations and - of course - the food and presents. Although he's not a big fan of snow.

8. His best friend is a strange masked cat named Skipper ( @Draco-Felis's character). It's not clear how exactly they met, but Crowley is very fond of Skipper and actually treats him much better than the rest of his friends.

(Done)

I love the crow boi
