I've tried using a Jigglypuff (> Wigglytuff) in FireRed ten years ago. {XD} I'm not sure if it's decent as a Fairy-type now. But it sponges the Special-type moves in Gen II quite well. :) I believe Jigglypuff's your final member. :'( As Altaria isn't allowed as you said.
Perhaps a SIngapura Cat?
Known for its petite size. It is the smallest cat breed, yet muscular for its build! So I can see it learning Play Rough and other hard hitting move. Fairy-type needs a speedy hard hitting physical attacker like a Weavile! :)
Congrats! I hatched myself a shiny Eevee last month, which is Timid in nature but has zero IV on Sp. Atk. :'( I wanted myself a Blue Sylveon, I'm not even asking a specific gender. T^T
Awww... Snubull is cute. :'(
Its line has access to Close Combat, Earthquake, Thunder Punch, Fire Punch, Ice Punch, Crunch, Heal Bell, Rock Slide, Wild Charge and Stone Edge. The only bad thing from Granbull is its low defensive stats.
It is Fairy type because it is
the Fairy Pokémon.
A big yes for Sweet Kiss, but nah for Jynx's signature move! {XD}
Disarming Voice is Fairy-type like Charm, because the user uses an enchanting/charming voice to the opposing Pokémon, which are the very definition of Fairies: charming, playful, enchanting.~ ;)
