I kind of hate everything about this entire line. Impidimp is a much shittier looking Sableye, and it's evolutions look like complete ass, too. We already had Hatterene in gen 8, and it pulls of the whole "small creature uses its hair to make itself look bigger" way better Grimmsnarl ever could. I also hate that a dual typing as cool as Dark/Fairy was wasted on these garbage designs when it could've went to something cooler like Mega Absol.
There's nothing redeeming about this line at all. I genuinely don't get how people have so much shit taste to actually call it good.
