What Almost Was: The Future of the Cybercops
The Nearly Sequel
According to the show's Wikipedia entry, the anime Armored Police Metal Jack was originally conceived of as a sequel to Dennou Keisatsu Cybercop before running into "complications" during production and eventually going it's own way.
Uchusen Magazine #102
In 2002, Uchusen Magazine published a two-page spread of original art by Tamotsu Shinohara which imagines the Venus-Bit armor as well as two additional Black Chamber accessories that could fill the empty spots in the original pack-in catalog. I had seen the image online but only discovered where it came from when I read a "Cybercop - Os Policiais do Futuro" blog post (sadly, the post is no longer available). After several years I was finally able to obtain a copy of the magazine.
The Venus-Bit armor is depicted as yellow with a rocket pack that includes two long thin stabilizer wings extending behind. The shoulders appear to have some sort of hinged flap. The helmet is similar to Mercury-Bit with the addition of two large oval "ears" mounted on either side of the head.
The image shows Jupiter-Bit wearing a large jet pack which is, unfortunately, split between the two pages.
Mars-Bit gets the most extensive accessory, a partial exo skeleton which includes dual cannons and claw arms. The cannons appear to elevate for use against airborne enemies and include braces over the shoulders that lock down onto his torso armor. The two claw arms appear to be attached to the outside of his forearms and connected to the backpack.
The Cybercops Project
In 2008 a group of Brazilian Cybercops fans made an attempt to create a CGI sequel to Cybercops. Since the home page for this project is no longer online, I'm working on mirroring their content on a dedicated page on this site.
