TenZ was a part of a science experiment to create the perfect aimer/gamer. Tyson was the tenth and perfect creation thus dubbed himself TenZ. All his other specimen brothers are spread throughout the world and his models are called NineZ and ElevenZ are making their way through.
Apparently, all subjects below NineZ failed, with NineZ becoming the first one into valorant. Unfortunately, the virtual reflex and hair enhancements were too low, so to compensate for that TenZ and ElevenZ were created, with TenZ having the reflex enhancers and ElevenZ having the hair enhancers. The other OneZ - EightZ were good in fortnite though.
