With Kamen Rider's 40 Anniversary movie presentation, opening this April 1, here's a special tv feature for OOO - Den-O - All Riders: Let's Go KAMEN RIDERS featuring some scenes from the movie itself! Isn't that awesome?!
OOO - Den-O - All Riders: Let's Go KAMEN RIDERS starts with Kamen Rider OOO fighting the Mole Imagins. When OOO is fighting them, he starts wondering "why aren't they bleeding Medals?" The Mole Imagins then disappears through a 10 year old boy. Suddenly, the Denliner appears and Kotaro exits. Kotaro takes out his Rider Ticket and goes back to the past in November 11, 1971. But why would a 10 year old boy have memories from 40 years ago?
Eiji and Ankh sneaks aboard the Denliner. They are advised by the Denliner Crew not to leave the train when they get to the past, but Ankh decides to sneak out in order to find all the Core Medals before the other Greeeds woke up, however this causes some serious trouble.
Back in 1971, Shocker found a Medal and used its powers and took over Japan. This resulted to the appearance of the Shocker Greeed (voiced by Hideo Ishikawa).
After the fight in the past, Eiji and Ankh returns and arrives at their own timeline only to see that Cous Cousier is now a restaurant called "Snack Amigo." By 2011, Shocker is already controlling over the whole world.
In order to repair time, Kotaro and Eiji travel back to 1971 once more. When they arrive in 1971, they meet Nokko, a member of the Rider Squad. They then discovers that Kamen Rider #1 and #2 lost the battle against Shocker and received a brainwashing surgery. They eventually became top soldiers for Shocker, and dubbed as the "Strongest and Most Evil Cyborg Monsters."
