>>46398748People talk about Chadsnarl anon, and whether you like or hate his normal form I think most can agree he has a sickass G-Max form (shame for when he loses it). Grimmsnarl's cool design also causes a bit of dissonance since it's most common usage is to just set up screens and be support instead of breaking backs itself. It can still run Bulk Up sets with some slight success, but it's not the best at it and it can be pretty easily killed if it tries.
Honestly it and Hatterene are 10/10 damn good fairies. I prefer the latter more, but they're both quite well designed, and even if they aren't top tier or used in more conventional ways I'm glad both Grimm and Hatt are really damn good with a solid niche carved out for both of them. Best duo in Gen 8 by a mile.
