Quartzer

The Quartzer are the main antagonists of the movie Kamen Rider Zi-O: Over Quartzer. They are a mysterious order of time travelers who appear be involved in a massive conspiracy behind Oma Zi-O.

The top level members of the organization all possess Ziku-Drivers that allow them to transform into "lost Heisei Riders", Riders that made their debut in the Heisei Era but are not considered a part of the Heisei lineup. The prophet of Oma Zi-O, Woz, is also a member of the organization.

History
Seeking to negate Sougo's transformation into GrandZi-O, the Quartzer conspire to assassinate Krim Steinbelt before he can create the Drive Driver, thus negating the creation of the Drive Ridewatch and, in turn, the formation of the GrandZi-O Ridewatch.
