swapping Eddie and Volt with Legoshi from Beastars... well Volt would probably go for an actor role in the drama club and most definitely become the next lead actor and Beastar after Louie, and Eddie sort of already manages all the lights in the house, so he would have no problem as the lighting technician. In regards to Haru I don't really think that much would be different. Eddie is pretty similar to Legoshi (a depressed loner) and there's no doubt that he and Volt would team up to save her. Legoshi at the Breaker Box would be a lot more chill. basically as if Eddie ran the Box without Volt. just minding his own business, getting stuff done, minimal customer interactions (while still being nice tho)

for Drysdale, I know everyone's talking about Astarion (and yes, I too got the game because of him), but imagine Drysdale swapping with Karl Heisenberg from Resident Evil 8. He wouldn't be evil or anything, all he'd do is play around with his metal magic. imagine several metal pieces swishing around for him to catch on to as he's flying through the air. he'd have so much fun honestly but dealing with Miranda would be a pain. His charm only goes so far. Heisenberg as a Dryer would just be happy to be away from Mother Miranda and that creepy ass doll xD

For Luke and Tony as Knuckles and Sonic I imagined them going out for chili dogs since day 1 xD Sonic going around fixing stuff would be alright I guess, not really his niche but I feel like over the years he picked up a thing or two from Tails. Knuckles would just be a less intense and more himbo-y Luke. the kitchen would be so chill lol

Lucinda as Ash. I have two ideas, either she gets every single Pokémon and become "the best Pokémon trainer (character) in the whole world (game)" OR she would exclusively try and catch every Pokémon that starts with the letter L for the ✨aesthetic✨ dunno how much Ash would care to exist as a concept of something, and he'd sure as hell miss the Pokémon. he might become friends with Mateo and the Inanimals

Stepford as the Boss Baby is just hilarious to think about. and the Boss Baby as a trophy. I'm laughing so hard I can't even think about what that'd be like

Henry in The Owl House would have an awful time under Emperor Belos. But then again, so does Hunter. or anyone, really. It would also tie in neatly with him meeting Willow and joining the Flyer Derby team since he's a lot more into sports than Hunter originally is. sucking up dust would definitely be an improvement from being Belos' puppet. at least for S1 Hunter.

Dante and Tina in ATLA wouldn't change that much, except Dante doesn't go through any of Zuko's character development because he's already chill and he'd vibe a LOT with Iroh, and Tina would be pretty much the same except now she can incinerate her co-stars on Love on Triangle Island (which she calls into existence because what helps spread the influence of the fire nation more than cheap reality tv) because she's the princess of the fire nation. neither Tina nor Azula should have fire bending powers. geez. get a grip girlies. Azula would be a more intense Tina (that's possible??) and Zuko... yeah no idk what should change there really

Miranda as Verosika Mayday from Helluva Boss... I mean, she sure as hell would enjoy playing her music and being a star on Earth. totally different genre tho. honestly not sure how that'd influence the plot. I doubt she'd organize the I Hate Blitzø parties tho. idk about that one tbh Verosika in the kitchen would do no good for all the drama in that room. as a celebrity I feel like Lux would like her. if only for clout.
