rider's next theme
 

What do you think the next rider theme you want to be next after Drive? And the next key object?

A ninja, rescue, police(I know there are police riders but it's not really shown in their design, something like G Den-O would be cool) and spy theme would be cool

Collectible gimmick for ninjas could be scrolls or shurikens, I can't come up with anything for a recue, police, or spy theme

Dinosaur and Ninja.
