He seems like he likes to lounge on windowsills in tall buildings, peering down boredly at the bustling streets below him.

Probably knows martial arts of some form

 She's that friend with all the really bad ideas that everyone has to talk her out of

He was totally the type to hold onto his siblings' shirt/sleeve when he was a little kid becuase he was scared of getting lost in big crowds

The base of his wings are extremely ticklish. He either loves being touched there or will murder anyone who does, there is no inbetween 

vvv He's a guy lmaoooo as for the assumption who knows, he probably has tbh

She once killed someone for calling her Cruella De Vil.

 Hippolyte is a champion arm wrestler.

Loathes Pumpkinspice lattes because of the crime against the color orange ( but also secretly loves it).

"You seem like someone that people would mistake for scary, what with those mean looking eyes, but is actually a sweetheart if you get to know them."
