(Left) Brick: Tea or water, he has a delicate stomach and can't eat much. Drinking or eating anything can make him nauseous, however, he can stand things like chamomile tea by taking sips and such. Drinking slowly.
(Right) Barricade: Coffee, specially if it's cold since he dislikes hot stuff, though he'd add some milk to it. He can stand mild bitter flavors but hates sour flavors like lemon juice (he is fine with lemonade though) (He is almost always eating, specially cake so he can be found sipping iced coffee to complement his dessert)
(Left) Boomer: Tea with added milk and like a teaspoon of sugar or coffee with milk and teaspoon of sugar (Any hot/warm drinks are good to him) Though he likes soda on hot days or simply lukewarm water. (He doesn't like cold drinks that much)
(Right) Bruise: Frappés (iced coffee), he can drink coffee but he drinks it so slow the coffee ends up cold when he drinks it XD He loves every cold drink and cold treats. Though he can't eat much cause of his slow metabolism (yeah, he's self conscious)
(Left) Butch: Coffee, he is not fond of tea, though he also drinks it with milk and sugar xD
(Right) Brazen: Tea or (black) coffee are good to him, though beer is favorite beverage. He likes one or two sweet drinks but he majorly prefers bitter flavors.
Sorry for the extra details, I just like writing about these things xD Also, for people that recognize like half of the characters (since it's a fancomic after all) their preferences are based on my story and stuff that happens, it's not canon, but, since the other three are mine, that's on point ofc.
