zone is yusei

as the titel says i believe that zone is yusei from the future or yusei's son or something out that way

Actually he is a cyborg with the same image as Yusei. I call him The Terminator though.
Quoting wiki:
"Z-one (pronounced Zone), is a cyborg who assumes the identity of Yusei Fudo from an apocalyptic future, who has traveled back in time to prevent the destruction of mankind, albeit through unsavory means."
