S-Yaridovich9X, real name Sam Carey, often called by his online identity, Mase, also known as SuperYaridovich999, and sometimes shortened as "Yaridovich", "Yarid", "Yari" or "SY9X", is the creator of the Smash Fighters Z series. As the creator of the series, he is tasked with animating episodes and creating custom sprites to fit in, as well as having big influence over each episode's script, as one of the key series scriptwriters, and overall story for each saga and movie. Mase is a big fan of video gaming and anime & manga, and has a large knowledge of a majority of Nintendo franchises, such as the Mario, The Legend of Zelda, Kirby, Pokémon and Metroid franchises, as well as some other franchises such as Sonic the Hedgehog. Mase is a fan of movies such as the Marvel Cinematic Universe and the Kung Fu Panda franchise.
Mase's inspiration came from Alvin-Earthworm's flash series, Super Mario Bros. Z, as well as Dragon Ball, by Akira Toriyama.
- Mase's original online name was formed around his watching a Let's Play of Super Mario RPG: Legend of the Seven Stars, and having employed favouritism over Yaridovich, the third Smithy Gang boss in the game. The "Super" part of the name comes from the common "Super" in some Mario titles. It is unknown where the tiple nine originates from.
- Mase's newer online name was formed over the decision to create a "fresh" and "more in the now" name, shortening the first part of the name and replacing the tiple nine with "9X". The 9X was spurred on from video games using dates such as "20XX", such as Mega Man and EarthBound.
- Mase's online identity came about after he was messing around with the first few lines of the song All Star by Smash Mouth, using Google Translate. "Mase" was a recurring term he came across, and he opted to use it as an online identity.
- Yari has also used the online username "Hardware34", which has often been shortened to "Hardware". This name spawned from the inability to choose a good PlayStation Network name, picking it at random.
