QwQ She's so precious. Just look at her wittle face.
I'm also willing to bet Slyveon will be Flying type, just based on the name alone. But there's also the color scheme and the overall design. The colors remind me a lot of Skyla from Gen V, and it has kite tails on its ear and even longer ones on its chest. Also Sylv is seen as an interchangable with Sylph, which is the spirit of wind for those of us who have played games that allow you to summon Sylph.
True. The other rumor is that Slyveon will be Light typed because they're adding it in for the Fairy egg group. I highlyl doubt that's the case though, there hasn't been a need for an additional typing since they needed to nerf Psychic types. Besides, if they add it and they add it poorly, it'll just ruin the set up all of us long time pokemon fans know and then we'll have to relearn everything in some new, unbalanced fashion.
