Brennan Marcel Williams, born on February 5, 1991, in Easton, Massachusetts, began his athletic journey in American football. He excelled at Catholic Memorial School, earning numerous accolades including PrepStar’s High School All-America team and being named all-conference as both a junior and senior. His collegiate career continued at the University of North Carolina at Chapel Hill, where he played for the Tar Heels football team from 2009 to 2012, earning honorable mention All-Atlantic Coast Conference honors in his senior year despite a labrum injury. Williams was then drafted by the Houston Texans in the third round of the 2013 NFL draft, marking a significant milestone in his football career. Although injuries limited his NFL tenure with the Texans, Jacksonville Jaguars, and New England Patriots, his foundation in professional athletics set the stage for his next venture.
Transitioning from football, Williams pursued professional wrestling, training under WWE Hall of Famer Booker T. He made his professional wrestling debut as Marcellus Black in Booker T’s Reality of Wrestling promotion in February 2016. Later that year, he signed with WWE, initially training at the WWE Performance Center. In 2019, he adopted the ring name Dio Maddin and transitioned to commentary for 205 Live, then Raw, alongside Vic Joseph and Jerry Lawler. This unique role showcased his versatility before he returned to in-ring competition as Mace, joining the stable Retribution in September 2020. This period saw him adopt a distinct persona, including a mask and a notably altered physique, marking a significant shift in his wrestling career.
His WWE career continued with Maximum Male Models, alongside Mansoor, before their departure from the company in September 2023. Post-WWE, Williams, now wrestling as Mason Madden, formed the tag team MxM Collection with Mansoor, making independent circuit appearances and eventually signing with All Elite Wrestling (AEW) and Ring of Honor (ROH) in 2024. Beyond wrestling, Williams has expanded his brand into other media, appearing in tabletop role-playing YouTube streams and re-launching his YouTube channel as a VTuber named JiBo. His diverse career highlights a continuous evolution and engagement across various platforms.
