The protag of SM (Don't care about USUM, it ruined the plot) is a selfish prick if you ask me.
Lusamine constantly praised them and yet they still sided with Lillie. You know what I would've done?
If I was there when Lusamine disowned Lillie as her daughter in the Aether Raid, right then and there I would've told Lillie to fuck off too and offered to be her new child. I'd love to have Lusamine as my mommy, fuck you Lillie you selfish harlot. And besides. Is her plan really that awful? (The SM one of course, fuck USUM) The Ultra Beasts are some of the coolest and most interesting new Pokemon in ages. I wouldn't mind introducing a shit-ton to our world. I'd love to own a Buzzwole and Xurkitree.
Protog is a fucking looser, so is Lillie. Mommy Lusamine was right.
