Kamen Rider V3 vs. Destron Mutants

Kamen Rider V3 vs. Destron Mutants is the second movie based off the Kamen Rider series, Kamen Rider V3. Unlike the previous Kamen Rider V3 film, it is an original work and not based on an episode.

Synopsis
A physicist named Tetsuo Okita discovers a new mineral called "Satanium," which is more powerful than uranium and emits destructive effects to anyone exposed to it. However, Destron abducts Okita in hopes of finding the source of Satanium and collecting more of it to expedite their run for global domination. Kamen Rider V3 must act fast in rescuing Professor Okita and preventing Destron from collecting more of the deadly mineral.
