How about this? A police rider who arrests kaijins with cards. So a mixed bag of Blade, Dekaranger, Blade with the aesthetic of G3 from Agito. And for good measure give Gotchard an aardvark motif and says "Gotcha!" after rider kicking the kaijin and then arresting it with a card Blade style. :lolol
Side note I do think a bounty hunter rider would work with the 2nd rider being the cop as well. Kinda like Kaiketsu Zubat but Kamen Rider. And make it an aardvark. :lolol

Are there any animals that have not been touched on KR yet? Like an anteater? Sloth? Echidna? Capybara? Raccoon? Sugar Glider/Squirrel? Porcupine? Badger?

Scarab maybe? I mean we had it as a kaijin in Blade but not as a rider if that's what you're asking.

An Egyptian-style rider would certainly be an interesting and eye-catching addition to the existing ones. Plus, it would be a good reason to bring back the Ambassador of Hell in the movie/HB. Or take an example from Wizard and remember Mysterious Nile Girl Thutmose. On the other hand, all the coolness of a scarab disappears when you remember that it is a dung beetle. Although, again, there was no plumbing rider yet.

And bring back some of the archeology stuff from Kuuga? Sold. :rock:

Will with the name of Gotchard

The last part of his name sounds like Shard so I'm guessing whatever the gimmick of the show will be will be some kind of shard base item.

If the main weapon is called the Daisoumaru or something like that (i.e. referencing the arcade games where cards and other collectibles are used to play), then it's a safe bet that the collectibles are cards.

Um, but Geats uses ID-Cores and rider buckles, not bullets.

It really is kind of fruitless to try and deduce the methodology of a Rider from the name alone. Who would’ve even guessed like Revice used stamps? Or Geats using… whatever you’d classify his stuff as.

The next rider season better have one of the riders be based off of a vampire. Or at least a werewolf.

We've had zombies out of Genm & Buffa. We haven't seen a vampire-based rider since Kiva!
