Mr. Mime and Chikorita.

Incineroar and Meowscarada

Sneasler Mr Rime and Mime

Smeargle.

Do I need to explain?

Its probably very obvious by now

Who tf hates Jirachi

Lickylicky

Hmm

Therian Tornadus and from my experience, Eternatus (both forms).

I can't really think of a 'mon that's really hated that I like. There are a few that are very underrated though, like Blacephalon, Diancie, and again, Therian Tornadus

Clawitzer

Miltank (not Whitney's Miltank tho)

Alcremie

I personally love Sneasler.

This dang weasel cat is such a stereotype and it’s hilarious. I also have a soft spot for any fighting-type.
