Recently, the new episode of Twilight Wings focused on Hop and his bond between Wooloo. This made me think, how do kids under 10 have pokemon? Bonnie has Dedenne, Hop has Wooloo, and I’m pretty sure there are others. Would there be any law about this? Also, how do you think it will work if the kid won’t become a trainer?
Well, the anime has said you become a trainer when you turn 10, but the games have also had trainers who are pretty clearly younger than the player (who in Red and Blue we usually assume to be about 10) from the beginning. There also seem to be people who have Pokémon companions but aren’t trainers (like, think even of Professor Oak’s opening monologue in the very first games; trainers are just one of several groups of people who live alongside Pokémon); you could probably weasel your way around a lot of rules if, say, your family has a Pokémon pet that technically “belongs” to your parents, but likes you enough to fight for you and take commands. I think the situation is much more flexible than, like, getting a formal license on your 10th birthday, without which you are at risk of having a Pokémon confiscated, or regulations to that effect. I also doubt all regions have the same rules. There might only be age limits for the gym challenge, or for leaving on a journey with your Pokémon; some kids might have known their partners for years before “officially” becoming trainers.
(Besides, I don’t think we know Hop’s age? He might not be 10 at the beginning of the story of Sword and Shield; he clearly hasn’t finished growing but I could believe he’s, like, 13 or 14?)
