Jun Honganji

Jun Hongnaji (本願寺 純) is the trouble-hating Police HQ Chief. A man who is very into fortune telling and feng shui, he is seen wearing different ties on different days that matches his lucky color for the day. Because Shinnosuke tends to slack off, he assigns Kiriko to watch over him. He also has a very peculiar speech pattern. He later becomes the first user of the Mass Produced Mach Driver, transforming into a Production Model Mach, which he refers to as "Kamen Rider Jun" (仮面ライダー 純).

History
In episode 25, it was revealed that he already knew of Krim Steinbelt, having the two being old colleagues as well as Shinnosuke's identity as Drive and secretly supporting them by founding the Special Investigation Unit. Eventually, he even purposely exposed Shinnosuke and Go Shijima (Kamen Rider Mach)'s identity to the worldwide under the assumption that it would come in handy. Honganji was also a colleague and friend of Shinnosuke's late father, Eisuke Tomari.

Super Hero Taisen GP: Kamen Rider 3
During the events of Super Hero Taisen GP, he is still the same Jun like in his original timeline, especially in helping Kotaro Minami to hide inside Drive Pit. When his cover is quickly found out by Shocker, he is killed after being tossed out a window of the driver's school the Special Unit is operating in by "Genpachiro Otta", known as Cheetakatatsumuri, while Rinna and Kyu manage to escape the villains' raids. His death is undone upon the timeline being corrected.

Kamen Rider Jun
Rider Stats
 * Height: 171 cm.
 * Weight: 62 kg.
 * Punching Power: 2.5 tons
 * Kicking Power: 3.7 tons
 * Highest Jump: 6 m. (19.68 ft.)
 * Fastest Speed: 100 m. per 7 seconds (31.95 mph)

The first version of this form was still a prototype due to technical bugs that immobilized the user. Rinna improved the later version of the mass production model, thus this bug has been fixed.

In terms of stats, it is clear that this is meant to be a mass-produced Rider unit, as the weak stats, weaker than any of Drive's forms, have not been seen since Den-O's Plat Form. Compared to Plat Form, this unit has slightly more offensive power, a weaker jump, and a faster running speed.

Equipment

 * Mach Driver Production Model - Transformation belt
 * Tokujo-ka Key - Transformation key, based on a redesigned Tridoron Key.
 * Pikopiko 3 - Originally used by Genpachiro Otta, now retrofitted into every suit.
