Even though it is fanmade, I think Wizard, Drive, Build, and Saber having red backgrounds is correct.

Edit: The image is now my avatar

See how well the image is organized. I don’t know what all the Riders will be

I mean, with Daiouika’s colors, if it gets turned into an Auxiliary Vistamp, it would probably be X.

What about this Turtle Vistamp that just appeared? It’s the red-and green one George was looking at near the end of Episode 8. If I remember correctly, Nigo has red and green on him.

V3's main colors are green and red and he was mortally wounded by Turtle Bazooka before receiving emergency surgery to become a Remodified Human.

Which animals will be suitable Vistamps for the Reiwa, Heisei & Showa riders?
Reiwa:

• Revice: Rex
• Saber: Swordfish?
• Zero-One: Giraffe?

Heisei:

• Zi-O: Brachiosaurus
• Build: Stag Beetle?
• Ex-Aid: Jackal
• Ghost: Ankylosaurus or Owl?
• Drive: Velociraptor or Snake?
• Gaim: Mantis
• Wizard: Owl or Salamander?
• Fourze: Gorilla
• OOO: Macaw (Parrot)?
• W/Double: Eagle
• Decade: Megalodon
• Kiva: Crab?
• Den-O: Mammoth
• Kabuto: Bear?
• Hibiki: Bull? Octopus?
• Blade: Cassowary or Rhinoceros?
• Ryuki: Smilodon or Tiger?
• Agito: Moose or Elk/Deer?
• Kuuga: Lion

Showa:

• ZO: ?
• J: ?
• Shin: ?
• ZX: ?
• Super-1: ?
• Skyrider: ?
• Stronger: ?
• Amazon: Mole?
• X: ?
• Riderman: ?
• V3: Turtle?
• Nigo: ?
• Ichigo: Grasshopper

We have 3 new Vistamps based on Showa Riders for Demons to get his Genomix forms.
Amazon-Mole
X-Scorpion
V3-Turtle

Yeah, Demons is definitely our Showa rep.

I feel like Drive Snake would have a Snake curled over its own tail acting as the Shift Tire.

I figured Drives could be specifically the Type: Formula and based on a hammerhead shark.

Also, I hope they use Snake/Cobra as the main form of another Rider to complete the "Ichigo reference trifecta" along with Evil and Demons
