An online special, with can be viewed here.
The Special Unit hears rumors about a powerful Roidmude called... the Zunbo Ganbo. Gou, confident as always, goes alone to defeat the terrifying new foe. This leaves Shinnosuke, Kiriko and Mr. Belt to recap the Riders arsenal in preparation for the confrontation with the Roidmude. Then Mach gets soundly defeated. The only thing he saw was a red Viral Core being given to a man who then fused with it to become a new kind of Roidmude.
- The Dreaded: The Zunbo Gunbo Roidmude.
- Foreshadowing: All clips in the special were taken from past episodes... with the exception of the scene where a Roidmude bestows a red Viral Core to a human.
- The Unseen: We never get to see Zunbo Gunbo.
- Recap Special: Done in an amusing style, with the cast dubbing over the scenes while searching for the "terrifying" Zunbo Ganbo Roidmude.
