Riderman is a the second installmet in my version of the Kamen Rider Series.
After the original Kamen Riders defeated KOTO and stopped Project Purge an evil terrrorist organization called SHOCK took over the country. One day one of their many quilt-striken scientists rebelled, but later got captured and has his arm cut off as punishment. He is then cast out and left for dead. He is rescued by a rebel doctor who gives him a prosthetic arm that can transform into a laser-canon, and gives him the power to transform into Riderman. He is later joined by a young man who calls himself a rider despite not having any powers. With a side-kick by his side Riderman now seeks revenge on SHOCK for everything it's done to him, Japan, and the world.
