- The Danza: Goro Inagaki as Goro, the titular hero.
- Keep Circulating the Tapes: The only way to watch this is from unofficial archives, either from fansubs or random video uploads, as Toei doesn't own the character as well as the short.
- One-Episode Wonder: Can be viewed as the first episode of the Kamen Rider G series that never was.
- Production Posse: An official SMAP-sanctioned outing, it stars band member Goro Inagaki and his real-life girlfriend Yumiko Shaku. Fellow member Tsuyoshi Kusanagi appears on a poster.
- Prop Recycling: The G suit is pretty much the original thing there. Then again it's a 20 minute parody, so just be grateful for that.
- G's Cool Bike is the reboot V3's Hurricane from Kamen Rider: The Next.
- The Shade henchmen transform into Worms from Kamen Rider Kabuto. Daido Oda is the Phylloxera Worm from the then upcoming Kamen Rider Decade.
