Here's the first scan of Kamen Rider Zero-One and his Henshin Belt → Hiden Zero-One Driver. The word "Hiden" is written with the characters to mean "Flight" & "Electricity". Zero-One needs to use Progrise Key to transform (Progrise). His primary state Progrise Key is Rising Hopper.

Ability is Jump. It's good to see a Grasshopper based Rider on the beginning of Reiwa Era.
Toei had announced the Press Conference for Kamen Rider Zero One with a fake News Video which features a News Caster with strange Ear piece, blue eyes & a strange tattoo on her body. Could she be a cast of Kamen Rider Zero One? Her name is referred as Maki Announcer. When I checked the list of TV Asahi Women Announcers, there was only one Maki Announcer whose face didn't match with the Announcer in the above video.
TV Asahi Staff had created a new button in their navigation menu for the page. It says "Coming soon...". The link to this button is https://www.tv-asahi.co.jp/reiwakamenrider/. This could be the link to the Official Kamen Rider Zero-One whose title is still not officially announced. Since Zero-One Title is still not announced, may the path is /reiwakamenrider instead of /zero-one or something.
