Quartzer

"We are Quartzer, the Wardens of Time!"

- Barx announcing his organization in front of Sougo

The Quartzer (クォーツァー) are a mysterious time-traveling group who appear in Kamen Rider Zi-O: Over Quartzer.

Overview
All of their members are men wearing attire similar to Black Woz, who later is revealed to be one of their members. Their leader Barlckx wears a red-color variant of the robe and sits on a throne.

Amongst the Quartzers are select group of Oma Zi-O-like Kamen Riders who are able to utilize the Ridewatch powers of Kamen Riders who were presented in the Heisei Era but not considered part of the Heisei Rider line-up.

History
They intend to kill Krim Steinbelt before he creates the Drive System in order to erase Kamen Rider Drive and Kamen Rider Mach from history, thus negating the creation of the Grand Zi-O Ridewatch. They also appear to conspire against Sougo Tokiwa.
