I advocated against Bayo for awhile here, so I guess I should speak up.
I just didn't think it would happen because, in addition to the nudity/gun thing, I didn't think Bayonetta was a big enough franchise to warrant an inclusion in Smash Bros. Every other third party in Smash has been a highly iconic gaming mascot of sorts, ranging from Pac-Man to even Solid Snake. As good as Bayonetta's games are, in terms of impact and fame, they're kind of small time in comparison to Sonic The Hedgehog, Final Fantasy, and so on.
But, I do understand why she got in, and that being because she was apparently the most realistic popular choice from the ballot. Quite frankly I didn't even know they were gonna take that thing seriously at all lol. But I digress. Overall, congrats to the Bayonetta fans out there. She wouldn't of been my first pick but she does look really fun and interesting, and sometimes I guess that's all that matters.
