Following the finale of Kamen Rider Build, Toei announced a Hyper Battle spin-off for Kamen Rider Rogue. Titled “Televi-kun Hyper Battle DVD: Kamen Rider Prime Rogue,” the spin-off will feature an upgrade form, Kamen Rider Prime Rogue; the form is shown to utilize a variant of the FullFull Rabbit Tank Bottle that takes the form of a crocodile head. Furthermore, the Hyper Battle video will address why Gentoku began wearing a leather jacket in the series.
Now, more details on this Hyper Battle will be revealed in Televi-kun magazine’s October 2018 issue; the issue is set to hit stands on September 1st.
