>>45839992Lumineon was the Pokemon I used for beauty contests in Pearl and I love it for that. It was nice to have a decently fleshed out optional sidemode where any Pokemon could shine.
I don't think every Pokemon needs to have some unique niche or gimmick, I think it's fine to add "filler" Pokemon just for the sake of ecodiversity and worldbuilding. There are so many species of fish in the real world and the series mirrors that, would it really be better to have an ocean filled with nothing but Magikarp to avoid redundancy?
