With OOO - Den-O - All Riders: Let's Go Kamen Rider premiering this April 1st in Japan, it seems that Toei is now starting to plan about OOO's upcoming summer movie! Asides from the earlier rumored special version of OOO Tatoba Combo, someone who claimed that he attended a meeting for the said film brought in sketches of the summer movie-exclusive Rider!
The image on top of this post is the front symbol of the Combo this movie-exclusive Rider will have. This Rider's Combo is similar to OOO's Tatoba Combo which has different colors. The head is of a Sasori (Scorpion), arms and torso of a Hachi (Bee/Wasp) and legs of a Kumo (Spider). This Rider uses poisonous attacks and like most movie-exclusive Riders, this guy is said to be evil.
Most fans have mixed opinions with this movie Rider since it is highly unbelievable in the first place and might be some guy who likes to spread false rumors. Just like we always say, take these rumors as a grain of salt.
