Bayonetta is the protagonist of the eponymous video game series by PlatinumGames that have been published by Sega and Nintendo. She appeared in the 58th episode and Season 3 premiere of DEATH BATTLE!, Dante VS Bayonetta, where she faced off against Dante from the Devil May Cry series. She was voiced by Marissa Lenti while her partner Jeanne was voiced by Dawn M. Bennett.
Bayonetta was born in Vigrid from the forbidden union of a Lumen Sage called Father Balder and an Umbran Witch called Rosa: the Witch was imprisoned and the Sage exiled from his clan. Bayonetta's birth caused a rift between the formally peaceful clans and eventually led to them engaging in a war. Bayonetta became a black sheep among the Umbran Witches, and during the war, Jeanne, a former childhood friend and rival, seals her away from the world while wiping her memory to protect her from those who would exploit her. For the next five hundred years, she is sealed in a coffin at the bottom of a lake. She is later rescued, at Father Balder's instructions. She goes in search of her forgotten past, heading for her old home of Vigrid, and fighting the angelic forces of Paradiso on the way.
Bayonetta is the fifth combatant to get a professional voice actor from FUNimation. The first four being Iron Man (voiced by Chuck Huber), Solid Snake (voiced by Christopher Sabat), Tifa Lockhart (voiced by Tia Ballard) and Tai (voiced by Todd Habberkorn).
Bayonetta and her opponent share a creator, Hideki Kamiya.
Bayonetta is the second female combatant to lose against a male combatant. The first was Riptor against Yoshi. Followed by Erza Scarlet becoming the third losing against Roronoa Zoro.
She's the first Sega combatant who is a female. She is also the third Sega character who is a human being, the first being Dr. Eggman and the second being Segata Sanshiro.
Bayonetta, along with Jeanne, are the only Sega combatants who utilize firearms and magic throughout their fights (unless one were to count the mystical Chaos Energies wielded by Team Sonic and Shadow).
Bayonetta is the third Sega character to have been killed by a non-Mario character. The first was Shadow, who was vaporized by Vegeta's Final Flash, and the second was Dr. Eggman, who was obliterated by Metal Sonic.
Bayonetta is one of the few death battle losers who technically didn't die. As revealed in Bayonetta 2; after having their soul dragged to Inferno an Umbra Witch still has a period of time in which they can escape Inferno and return to Purgatorio. Due to Jeanne winning her DBX its highly likely that Bayonetta escaped Inferno.
Nearly a year after Dante VS Bayonetta's release, Boomstick headed a ScrewAttack Top 10 video of his Top 10 waifus and placed Bayonettta as #1.
