So, if Demons' Vistamps are based upon Showa Riders with the animals being based upon the most famous/familiar monsters from that series, what could the other Vistamps be based upon?
So, there are Stronger, Skyrider, Super-1, ZX, Black, and Black RX. I am classifying Black RX as separate to Black, even though it is an actual sequel. However, J could also be included.
Meanwhile, the Heisei Riders that so far we don't know the Animal that the Vistamp is based upon are Agito, Ryuki, Blade, Hibiki, Kabuto, Kiva, OOO, Wizard, Drive, Ghost, and Build. There are rumors that the Wizard Vistamp is going to be the Owl Vistamp. Looking at the Animals on the Tree of Life-based ink painting in the opening, besides the Vistamps revealed before the show, there are a Moose, a Whale, a Bull, a Turtle, a Crocodile, a Snake, a Frog, a Macaw, an Owl, a Toucan, a Swordfish, a Cassowary, a Smilodon, a Jellyfish, a Crab, a Salamander, a Butterfly, an Ammonoidea (Ammonite for those who don't know), an Axolotl (A-X-O-L-O-T-L, my time has come to burn! I invoke the ancient power that I may return!)*, a Scorpion, a Coelacanth, a Velociraptor, a Plesiosaur, and an Archaeopteryx.
So, the Scorpion and the Turtle both later became Vistamps. That means that any of these could become any Rider. The question is which would become which Rider?
Just something to give you guys some speculation fodder.
