Doktor G! The True Form of Evil is...?

The Destron Hunters discover that the microfilm gives the location of a manufacturing plant where Destron creates their mutants. While they succeed in sabotaging the plant, Doktor G arrives to exterminate them, except for Sakuma Ken, who is saved by V3. Doktor G implores the Great Leader to allow him to destroy V3 personally, and transforms into Crab-Laser. Will this be the end of Destron… or Kamen Rider V3?
