Don Sonnellino, better known as Mafioso, is a Minor antagonist in the 2024 Roblox asymmetrical horror game, FORSAKEN, serving as the main antagonist of Chance's storyline. He also appears as a playable skin for C00lkidd.

As his alias suggests, he is the leader of the Sonnellino Crime Family, and is known for causing havoc wherever he goes, most of which is done as part of a campaign to hunt down one particular person, that being Chance. He wants to reclaim the money that Chance won in his casino, presumably thinking that Chance cheated at one of the games (that moron was just very lucky). His Sonnellino family comes with four named ranks, that being Soldier, Contractee, Consigliere, and Caporegime.

He appears as a typical Mafia gang leader, wearing a black fedora covering both of his eyes, along with a long black overcoat, white dress shirt, and a striped tie. This gives him classic 1920s-30s gangster vibes. He also takes on similar appearance with Chance, except Chance has sunglasses on, making him feel more like a cool gambler dude.
