What mundane uses for all the kids powers can you think of? For rose I think she would be able to always win the lottery since she would know what numbers win, but that's about all I can think of
I don’t think she’d have much use for the lottery though, they’re already Gods, and have Alchemiters. She’ll totally use her powers to beat your ass at just about any game though. Dave likely doesn’t use his powers anymore, but if he ever forgets something or is late somewhere, he could just pull his Timetables out. John could fan himself on warm days or dry himself off after shower. Jade gets a power downgrade, but still, changing sizes and momentum sounds like a super convenient power for everything, and who knows if there are still Bec things she can still don.
Jane can heal any wounds as long as is not resurrection, and she can resurrect a bunch of other people still. Combine it with the fact they’re all God Tiers that have won, when the Heroic/Just thing may become way harder, and I bet they’re all super reckless now. I don’t think ripping someone’s soul has much of a practical use, but if he can dim someone’s feelings he could make it hurt less when there’s a break-up or something, perhaps he’s just excellent consoling others and himself. Jake, if he hones his skills, could have the boundless energy of hopeful optimism and belief bend to his will- But it’s a bit overshadowed by the fact Roxy can already easily create things, which is FURTHER overshadowed by the Alchemiters. At least Jake may be able to pull out some Deus Ex Machina nothing else could, and Roxy can still go invisible/intangible to play pranks on people and spy on them.
