Grimreaper Chameleon (死神カメレオン Shinigami Kamereon, 6, 7, 13 & Rider vs Shocker) (a.k.a. Chameleon Man (カメレオン男 Kamereon Otoko) - A chameleon monster skilled veteran in the expertise of fencing. He can turn invisible at will, but still casts a shadow. He also bears a tongue that can be used for lashing or strangling. His plan along with Shocker loyalist Dr. Heinrich is to find the treasure map to a hidden Nazi treasure buried in Japan during the WWII Axis Alliance. It turns out the treasure was already seized before Shocker or Hongo found its location. He was destroyed by Kamen Rider #1's Rider Kick and Rider Chop.
He was later resurrected by Shocker as part of the Revived Kaijin Army before being destroyed by Tokageron's special bomb. Grimreaper Chameleon also made a brief return appearance in the monster army of the Kamen Rider vs. Shocker movie, but did not actually have an active participation there.

- Lasting two episodes unlike his predecessors, Grimreaper Chameleon is the first example in the Kamen Rider Series of what can be more accurately termed monster of the fortnight rather than "monster of the week". This would become especially commonplace in the Heisei era, particularly during the years 2007-2013.
