Billy is a friend of the Best Friends Zaibatsu who has occasionally made cameo appearances in their videos. Until episode ninety-eight of the Friendcast, he had yet to actually say a word on the channel. He debuted in Fighterpedia in the Ode to Grapplers. He was later named in his second appearance, The Arcade Stick: A Gentleman's Guide. Billy was seen in the DIVEKICK episode behind the wheel of the Shame Car, presumably about to take Matt, Woolie and Liam out for a shame drive. He is commonly seen toward the end of live streams where he is referred to as "Vicious Billy".
As of January 17th, 2017 it was announced that Billy will be the official video editor of the Super Best Friends Play channel.
He is known for his thick accent, penchant to yell at Chinese ladies at McDonalds, and nodding off while driving 120 miles per hour, as stated in the Deadly Premonition full Let's Play.
- In episode thirty-two of the Super Best Friendcast, Richard Simmons is the Final Boss, Pat remembers that Billy's favourite Devil May Cry game is Devil May Cry 2, much to the Zaibatsu's disgust.
- In episode forty of the Friendcast, The Good Stuff comes from the 3rd Ass-chamber, the Best Friends see Billy walking past and interrupt their conversation to greet him, as they were recording outside.
- In episode ninety-eight of the Friendcast, Who Trashed My Baby’s Grave?, we hear Billy's voice for the first time as he explains his intentionally under-leveled playstyle in A Realm Reborn: Final Fantasy XIV to Pat, who believes that the majority of people who play like that are assholes. Pat agrees with Billy's stance under the circumstances that Billy is in fact "fucking good", and is henceforth allowed to play in such a way given his extremely high level of skill.
- In part thirteen of the Final Fantasy X LP, Woolie talks about how, when playing RPGs, Billy likes to max-out his characters' levels early on so he can blow through the game and feel overpowered.
- In part ten of the Naruto: The Broken Bond LP, Billy overhears Matt, Woolie and Pat talking about Dragon Ball Z and Naruto Shippuden. Billy steps in and can be heard in the background, answering the questions all three had. Woolie also says that Billy was still a fan of Naruto and "Never left".
- Billy uploads livestreams on his Twitch profile SoushinSen and his YouTube channel Soushin.
- Billy managed to make it in the news after grinding all the way to level 99 in Chapter 1 of Final Fantasy XV.
