Zero is the greatest idol of Kaz. He is masked and the number 1 racer in outer universe. He is also pressumed to be Taiga's older brother.
In the episode "Race to Space", Kaz sees him on the internet while researching about Team Gurao at night.
In the episode "The Masked Racer, Zero", he reveals himself on the race track near the end of the episode, as he was previously disguised as an old man.
In the episode "Dragon-Tiger Clash", Zero appears and Coach Dile states that from now onwards, Zero will be the teams instructor, much to Taiga's dismay.
