Kamen Rider! PUN!

What if there was a dinosaur rider, they'd do fossils.

Bird rider... batteries like Kyoryuger's.

Keys they can use the monster theme from Kiva again or a ninja rider.

Well they'll take pretty much any small, insignificant item & make it into something interesting for power. USBs, Coins, Switches, Rings (though that's a little bit easier to accept since they're wearable), Locks & now toy cars that shift like car handles. I've got absolutely no clue what they would do next. Maybe a writing utensil of some sort like a brush or pen?

Kamen Rider Painter?

Maybe. Something akin to the Shinkengers, with a dash of FMA would be cool. The show had a magic/art theme where they have to draw their circle in the air, the circle goes over them & that's the Henshin. They can change ink cartridges for various Form Changes.

If there was a main female rider to take over, what motif would you say would take it?

I don't think it matters. The gimmick is about the season's theme, not the gender of the main character.

Foils and sping tops would be kind cool.
I would love to see a show with a weapon like changer like. (drake, deind ect)

Main AR
secondary Sniper
ect ect.

Would like for the next two series to have...

Series one: Spinning tops like Beyblades

Series two: Wheels like the beywheelz

So kinda like Meteor's Storm thingy? That'd be cool.
