Well I'm not sure about Fairy, but sound was with it's less annoying brother, light. When the legends were revealed, people said "oh, rainbow equals light, light type comfirmed!" and "Noivern screams, looks like he's blind, and LOOKS LIKE A TUNING FORK when he flaps his wings(one of the stupidest reasons I ever heard)"
So yea, it was people simply not realizing that those types wouldn't work and would be stupid. --- gat mi swaeg ohn, aint ekven gun tuch meh.
Hiro put up a type chart that included fairy. I think that was one of the earliest instances if not the first.
But to be fair I think every gen brings talk of new types. I know people were saying light back during black and white. --- Black 2 FC: 3569 1730 6208 http://zettai-cosplay.deviantart.com/art/Skyla-Cosplay-244148531 my wife. Doesn't count Tiger, this ones real.
I find it funny that funeralcake said he/she was leaving yet still posts here.
And it was mentioned before that because of sylveons French name or something. But I think that was the first semi-official confirmation of it. --- Black 2 FC: 3569 1730 6208 http://zettai-cosplay.deviantart.com/art/Skyla-Cosplay-244148531 my wife. Doesn't count Tiger, this ones real.
