Her Wicked Weaves lets her use her hair to summon the limbs of the demoness Madama Butterfly in her smash attacks. The Witch Time, originally used to slow down time in the original game, functions as a counter-move that slows down her attacker. If timed late, she used Bat Within instead, reducing the damage she receives from enemy attacks.
Visual effects also accompany her movements: butterflies appear when she lands on her feet; roses fall off when she takes damage; butterfly wings appear on her back when she jumps mid-air, and magic circles appear when she jumps or fires her guns. Additionally, in the WiiU version, her shadow takes the shape of Madama Butterfly. also She has a uniquely long dancing taunt that you can cancel at any time.
In her Final Smash move, the Infernal Climax, she uses Witch Time and activates the Climax Gauge that she needs to fill up by attacking opponents in order to summon the Infernal Demon Gomorrah to attack everyone.
She has her look from Bayonetta 2 as her default look, but she is also playable in her look from the first Bayonetta. One of her alternate colors resembles that of Jeanne's.
She is planned to be released along with the Umbra Clock Tower stage from her first game.
Fire Emblem Fates' Corrin also join Smash
All Fire Emblem characters have counter slash moves assigned in the down + special move command. Corrin's down + special move is also a counter move, the Counter Surge, where instead of a slash, he transforms into a dragon and lets out a water current to wash enemies away. In his Final Smash, Torrential Roar, he can pull in enemies in whirling water and blast them off.
Final set of costumes for Mii Fighters
And finally, the last set of Mii Fighter costumes are revealed: Bionic Armor for all fighters, Takamaru (The Mysterious Murasame Castle) and Gil (The Tower of Druaga) for the male Mii Swordfighter; Ashley (Warioware, Inc.) for the female Swordfighter, Tails (Sonic the Hedgehog) for the male Mii Gunner; and Knuckles the Echidna for the male Mii Brawler.
These costumes, along with Bayonetta, Corrin and the Umbra Clock Tower stage DLCs are all planned to be released in February next year, and they ultimately wrap up the development work for Super Smash Bros.
Endnote: That's it, Super Smash Bros. for the 3DS and WiiU has got to be the greatest multiplayer fighting/action game in this decade.
