Hassan is of Palestinian-Jordanian descent, with parents originally from Jordan. He married his wife, Daniela, on the release day of Fortnite. The couple lives in Austin, Texas, where they manage multiple creative projects together. His family includes three brothers: Junior and Otto, who stream on Twitch, and Omar, who participates in live workout sessions.

In November 2020, Hassan overhauled his health routine and lost more than 60 pounds through consistent weight training and calorie management. The habit stuck. He established PK Flex, a community hub where he shared workout routines, diet strategies, and personal fitness updates with his audience. He frequently broadcasts gym sessions alongside his brothers.

He and his wife also keep several pets at home, including their dogs Aegon, Aiko, and Yuna. They previously created a pet-focused channel called Life With Aussies to share videos of their animals participating in challenges. Their household also includes two cats, Mikasa and Levi.

Hassan created his YouTube channel in January 2011, initially focusing on games like RuneScape and The Elder Scrolls Online. In April 2016, his Elder Scrolls Online account was banned for account sharing. He shifted his attention to titles such as Overwatch and For Honor before turning to Fortnite in 2017.

His channel expanded rapidly through his "How to Win" series, which offered educational commentary and strategic tips for Fortnite players. In November 2020, he signed an exclusive streaming contract with Twitch. Fortnite honored his community status in February 2021 by introducing a customized locker bundle. In September 2022, Epic Games added an official Icon Series outfit and cosmetic bundle bearing his likeness to the game.

Beyond regular broadcasts, he has taken part in brand collaborations within game ecosystems. In June 2022, he partnered with Honda to launch the "Hondaverse" custom map event inside Fortnite. His content work earned him an inclusion in the 2023 Forbes 30 Under 30 Games list and a nomination for Content Creator of the Year at The Game Awards.

In June 2020, Hassan and his wife founded Oni Studios to support digital content creators. The company provides video production, social media management, thumbnail design, and strategic business consulting. In late 2021, the studio moved into a dedicated office in Austin before expanding into a larger studio headquarters featuring production rooms and stream spaces.

Hassan launched the apparel line Metal Umbrella in July 2021. The clothing label blends elements of streetwear, anime aesthetics, and gaming culture. It operates as a lifestyle brand under the Oni Studios umbrella.
