Guido Mista, born December 3, 1982, in Italy, acquired tetraphobia—an aversion to the number 4—after a childhood incident where a neighbor’s fourth kitten clawed out its owner’s eye. Despite enduring poverty as a self-reliant teenager, he embraced a carefree existence, savoring sunsets, wine, and cheese. Known for greeting women warmly despite repeated rejections, he frequently escalated to violence when his idol, Clint Eastwood, faced insults, resulting in periodic arrests. At 17, Mista intervened in an assault on a woman by three men. Unscathed despite gunfire, he retrieved a firearm and neutralized the attackers with lethal precision. His subsequent 15–30 year sentence drew Bruno Bucciarati’s notice, who secured his release into Passione after Mista passed Polpo’s Stand Arrow trial, awakening his Stand, Sex Pistols. Mista balances casual charisma with ruthless pragmatism. Preferring instinct over deliberation, he engages in spontaneous banter yet devises cunning combat strategies. Though sociable, he taunts enemies mercilessly and enacts brutality without remorse—torturing Zucchero or menacing Pesci—while retaining a moral compass, rescuing civilians and recoiling at undue cruelty. Sex Pistols, his Stand, comprises six bullet-guiding entities numbered 1–7 (excluding 4), altering projectiles mid-trajectory. A sharpshooter by skill, Mista remains deadly without Stand aid, exploiting vulnerabilities like White Album’s airhole or outmaneuvering Sale’s Kraft Work via ricochets. His loyalty shines in critical arcs: defying fate by destroying the Rolling Stones Stand predicting Bucciarati’s death—leaping from a building to smash it—and pivotal battles against Sale, Ghiaccio, and Cioccolata. Partnering with Giorno Giovanna, whom he trusted implicitly, their synergy peaked in hijacking a helicopter through combined Stand abilities. Post-Vento Aureo, Mista survived Diavolo’s defeat, remaining Giorno’s ally as shown in *Purple Haze Feedback*. His attire features a knit cap with a downward arrow, zebra-striped pants, and a purple revolver, with adaptation palettes favoring vermilion, blue, and white. Mista revered Bucciarati’s leadership, instantly endorsing his rebellion against Passione’s boss. His bond with Giorno solidified through mutual respect, both emerging as the team’s surviving core. Beyond tetraphobia, superstitions include avoiding urinating near jewels and trusting divine aid in crises. These quirks, paired with his recklessly pragmatic combat style, cement his multifaceted persona.
