Emotional support... support?

Absol and Darkrai (canonically maligned, targeted, and ostracized for no good reason, and then its attempts to protect or isolate itself are only leveraged as more proof of its danger)

Mimikyu (pretty self-explanatory)

Type: Null, Silvally, and Mewtwo (living weapons that exist in the shadow of a more perfect counterpart)

Ralts line (obvious)

Chikorita and Popplio Line (standard 85% male starter gender ratio yet distinctly feminine and famously unpopular because of it)

Shedinja (the shape of something that should be there but isn't)

Latias (literally takes the form of a girl)

Dragonite and Goodra (hated for being "gay" dragons instead of "cool" ones)

Ceruledge (chuuni)
