Estella would pretend to be a champagne and martini gal, but really she's a beer chick. Beer and sangria

Wily doesn't usually drink for fun, so when he does drink it's usually the highest proof stuff like straight vodka to get hammered as efficiently as possible.
His Lab partner and his pokemon don't let him in the lab when he's drunk though, the Mad scientist in him comes out in force when he's wasted. Like "I'm inventing time travel just so everyone shuts up about that celery bitch Celebi, HE AIN'T SPECIAL!"

Jin is big on sake, or really most rice liquor. She’s a VERY friendly drunk, laughs a lot and is usually hugging at least one person every few minutes.

Mary actually picked up a taste for scotch/whiskey. But beer or even some fruity cocktails are another possibility. She’s usually a pretty talkative drunk, though she sometimes can get a bit handsy with Jin when she’s had a bit too much XD

Yorra: Gin and Tonic
Loud and punny drunk, could be highly mistaken for cute until she vomits on your shirt

Elio's generally not a drinker. But he can down a beer or two if the occasion calls for it.

Ardyn loves sake, but drinks it sparingly (want to keep his figure and alcohol isn't good for the body).
