Z-one

ZONE is revered by Yliaster as their "God", especially for the Three Emperors, whose goals seem to center around unleashing it. ZONE also is the one responsible for creating Bruno, for the purpose of stopping the trio.

According to Jose, ZONE was also responsible for the creation of Yliaster as a mean to set the course of history. Bruno himself has stated that ZONE is somewhat a God of Destiny.

Design
ZONE appears to be a machine shaped like a comma, the number 9 or the magatama, seen in an unknown area inside Security's main computer room. It has been shown in a close-up with a single visible blue eye, and human features. The eye visible has a striking resemblance to those of Yusei and his father.ZONE also resembles a 'Nautilus', a rare sea creature shaped like a shell.

Biography
ZONE first appeared when Sherry and Bruno attempted to scan her "Z-One" card, warping them and Yusei Fudo to a computerized world. After they all woke up near a lake along with Mizoguchi, Yusei speculated that it has something to do with Yliaster.

Later after reaching a Clear Mind, Yusei finds Shooting Star Dragon's Tablet outside the city, upon touching it he is once again transported to where ZONE is. It is there that ZONE gives him the respective card. This is because he has obtained an alternate possibility, meaning Accel Synchro and that same card has the possibility towards it. This is one of the requirements for Clear Mind. ZONE states that Yusei has the right to take it, as he departs saying that "all possibilities must be made equal".



Later, after being separated from Yusei and Bruno, Sherry LeBlanc winds up in the company of ZONE, in the form of her father. ZONE promises Sherry he'd tell her the entire truth of what's going on, but she'd have to accept her fate being altered.
