If we STILL don't get sidequests or special events for mythical/legendary pokemon in Sword and Shield , at the very least there should be an animation/short film uploaded on the official Pokemon Youtube channel where the pokemon's lore is revealed and we get to see its personality. It would give people a reason to pick them up.
Like Meltan. I wasn't interested in it at all, but then I saw that Rare Footage video and now I want 12 of them.
