Dizzy (Japanese: ディズィー, Hepburn: Dizī) is a character in Arc System Works' Guilty Gear fighting game series.

Introduced in Guilty Gear X as the game's final boss, Dizzy stands 5 ft 6 in (167 cm) tall, and is described as a woman with an "honest and pure heart" that hates conflict.

[9] In subsequent appearances her design was kept consistent until Guilty Gear Xrd, in which she was given a long white shirt that covered her torso and midsection, while emphasizing her cleavage.

After the events of Guilty Gear XX, she meets series secondary protagonist Ky Kiske, and after falling in love they have a child named Sin.

[2] In terms of gameplay, Dizzy was given a wide range of projectile attacks, but few defensive options outside of her high mobility, with players meant to keep opponents at a distance.

However, in Xrd, she received a variation of the concept with the move "Gamma Ray", where Necro would fire a large projectile before Dizzy pushes his arm away to protect the opponent.

[29] As part of a collaboration between Arc System Works and distillery Wakatsuru, the latter produced a malt whiskey themed after the character in 2024, to celebrate the Guilty Gear series' 25th anniversary.

[30] In another collaboration, this time between Team Ninja and Arc System Works, Dizzy's outfit from Xrd was one of several released as downloadable content for character Nyotengu in the game Dead or Alive 5 Last Round.

[32] Two 1/8th scale figures were released by model company Alter for her appearance in Guilty Gear XX Accent Core, featuring her primary and secondary color palettes from the game.

[36][37] Matt Sainsbury of DigitallyDownloaded.net described Dizzy as the "ultimate in fighting game characters", praising both aspects of her appearance as well as personality, but particularly for her sex appeal.

[38] In their review of Guilty Gear X, the staff of Gameshark described her as a character that "defies description", calling Necro and Undine "a devil and angel in her soul" and praising their appearances in her attacks.

[39] Japanese website ITmedia meanwhile compared her to a "special seafood bowl" due to her complex combination of traits such as her physical age, role as a mother, and character design.

[4] In terms of her character, Gavin Jasper of Den of Geek stated that Dizzy bucked a trend of sequel fighting games introducing a more imposing final boss than its predecessor.

[42] Destructoid writer Chris Carter also voiced some concerns over Sin's existence, stating it was possible "Dizzy could have aged a bit more by the events of Xrd, but it’s just...weird, even for Guilty Gear standards.

"[43] Necro and Undine were the subject of discussion in a dissertation by Perdosa Guilherme and Georgia da Cruz Pedrosa of the Federal University of Bahia.
