>>25111020Maybe they quit training, got older, and needed a day job. I haven't read any stories exploring the rift/drama that would create between a trainer and their pokemon. Especially if most of them were picked up for journeying and battling. I'm sure such stories exist, but I've never sought them out before now.
>>25110771That's an interesting point. Some pokemon lines rarely, if ever, reach their final forms without a trainer like the trade evolution mons. But with that in mind there should still be Kirlia around to look out for those weak Ralts, because wild Kirlia are a thing in the games.
