I was thinking about Silverhawks, Storm Hawks, Guardians of Ga'Hoole and Silverwing.

If there was a spy rider the. Since Go-busters?

Silverwing was a bat not a Bird.

Yes. But for a secondary rider he can be a bat and various animals that can fly.

Since Den-O's trains have time and ToQger's trains have imagination.... the concept of imagination can be used for a new rider series!

I thought it was funny in the Showa/Heisei Rider movie, from Gaim, that Den-O ended up as the legs of the ToQGer/KyoRyuRed/Den-O Mecha. What made it even funnier was that he complained about it the whole time.

Is decade more of a gokaiger or boukenger?

I feel Boukenger. He just has Gokaiger's anniversary-theme.

Speaking of I'd also enjoy a Pirate-themed Kamen Rider, though I would make the collectibles coins & that can't happen since OOO did that. Maybe tiny cubes that resemble treasure chests the size of Astroswitches.

Or a military-based KR with forms based on tanks, jets & battleships. That collectible could be something akin to badges of honor.

Maybe a ninja KR that utilizes scrolls as the collectible.

Perhaps even an angel-focused KR with various halos as a collectible, though maybe Agito throws this idea into the "Used" pile.

I think it would be cool if they did a throw back to Cyborg 009 for a Sentai theme where every Ranger are Cyborgs and have numbers in their names. For example: Aka1 and Aor2.

Unlike series with a large amount of Rangers like Kyoryuger, the extra rangers that they get stay on the main team until the show is over.

Who's a bad ass sentai that could be a rider by themselves?

If anything can be used for an anniversary-theme, I like Boukenger's adventure theme (Indiana Jones, Tomb Raider & Uncharted) plus Ohranger's geometric shapes. In fact, perhaps amulets can be used for that.

Military-based rider? Maybe that and a spy rider being the main hero. How would badges work? Like let's say.... Jetman is used.

Let's wait for Ninninger to see if there are good results that can be used for that, Kakuranger & Hurricanger. Scrolls I like. what about shurikens?

That's true on Agito. Got anything.... "Goseiger" mixed with "Garo"? Was thinking about angels and demons.
