First of all, I want to give credit to @dani0-0 for designing the characters, (I love your style :3)
I hope you give me permission to use them in a fanfic :D (If there is any problem, send me a message so I can solve it)
Translation from Spanish to English:
♤Mistery/leader (only when not near Wheezy)
The reason for his way of being is because he takes Whezzy as an example (since he is a father to him and to the others, he loves Chips very much but does not show it)
The tips of his hair are dyed black because Chips dyed them for him. His eyes are a mystery, as are his voice and true personality. Wheezy trusts him more because he is more responsible. Their wings are a little bigger
<Extra: she has piercings in her eyebrow, lip and nose>
His name means "destroyer of peace."
He has trouble following directions from both Mistery and Wheezy. He acts before he thinks. Wheezy and Mistery keep him away from weapons he can stab with, and because of that, he started fighting with only his fists.
<Extra: Prevents people from flirting with Chips, when that doesn't work ,he calls his brothers>
He uses his "polite and refined young man" appearance to get what he wants. He admires Chips, which led him to try to style his hair like him; when he failed, he kept his ponytail. Chips usually styles his bangs. His twin brother is Casimir.
<Extra: Just like Casimir, he prevents them from flirting with Chips, the four want Wheezy to tell Chips what he really feels>
He stutters (true to his name).
He's the youngest of the four siblings, and unlike them, he can't (yet) fly because his wings are smaller. He tends to be a bit sad, mistakenly believing he's not important in the group.
<Extra: People characterize him for his calm appearance, which he uses to his advantage. Quite aggressive when he gets angry.>
Sorry for my bad English, I'm not familiar with English speaking.
