Mafioso (canonically named Don Sonnellino) is the powerful, ruthless mafia kingpin of the Sonnellino crime family and the primary antagonist of Chance’s backstory in FORSAKEN, acting as a cold, imposing, and entirely humorless crime lord who wields heavy brute strength and a burning sword [fandom.com]. Canonically, he was once on friendly terms with Chance until the gambler won a rigged game at his casino and fled with the prize money, prompting Mafioso to launch a brutal, unforgivable blood feud to hunt them down for the debt [fandom.com]. In fanon culture, the community softens his terrifying, murderous aura to fit the "Doublefedora" dynamic, transforming him into a deeply stressed, grumpy, and highly dramatic "tsundere" who acts completely exasperated by Chance’s chaotic, flirting behavior but secretly harbors a deeply protective soft spot for them in an intense enemies-to-lovers rivalry (He is darkly obsessed with Chance and gets jealous easily, and he loves killing )
