Official League Records
The remainder of this article contains lore created collaboratively by the Blaseball community.
Mason is a former fashion model and heir. After a successful period modeling for his family's famed fashion brand Pinstripe, Mason left the Preston Compound in Malibu, California to "do research" on streetwear, having "grown jaded [with the] insular and elitist nature" of high fashion.
After moving to Van Nuys, California and meeting little success, Mason misread a flyer advertising a kickball league as a "knitball" league. Assuming this was a knitting club, Mason was further shocked upon arriving for the first meeting to realize he had actually signed up to be a professional blaseball player. Despite his best efforts, he found himself rooted in place, physically incapable of leaving the blaseball field. Owner Guy Myrington reportedly assuaged his fears by assuring him that he would have the opportunity to see many unique fashions in Internet League Blaseball. Mason contributed to the designs of the team’s uniforms as well as helped provide any equipment which Al Pastor did not. Mason has reportedly been inspired by the many fashion trends he's seen in the league, from creating faux-fingers to mimic PolkaDot Patterson's extra appendages, to wearing red contacts credited to the rogue umpire's red eyes being "very Glucci." He has since stopped wearing these contacts since the incineration of Nicholas Vincent.
While doing his best to get some sort of fashion going for the Tacos other than uniforms, Mason has spent most of his time repairing and fixing other teammates' outfits and fashion style. Recent fashion success includes Vito Kravitz, Wyatt Glover and Patel Beyonce. His most catastrophic failure is Mcdowell Mason.
Despite their disinterest in blaseball, Mason has been a stalwart of the Tacos having played the most consecutive games for the team. The performance of his younger teammates, Nicholas Vincent, Yummy Elliott and Wyatt Mason IV push him to perform better. As one of the senior members of the team, Mason has taken on a mentoring role. He often makes everyone very thoughtful gifts and stashes them in lockers or gym bags and never forgets a teammates birthday or special occasion. Mason made matching " Season 17 Champions LA Unlimited Tacos" jackets for everyone after they won, and wears his a lot.
When not playing blaseball, Mason spends time with their husband(who knows nothing about blaseball). Mason prefers wearing more "feminine" clothing and occasionally performs in drag shows. He can be seen hanging out with their best friend Wyatt Pothos. Some hobbies include knitting and going to fashion shows.
