Rider themes to be used for SS
 

Is there any rider themes Super Sentai can use?

Toqger used the train theme from Den-O except they're not about time, but about imagination.

How about if they used the monster theme from Kiva?

Maybe it can work as long as you can make it approachable enough.

If something kiva how gonna be the mechas ?

Have a monster sentai with each mecha and ranger based on a classic monster... red-vampire, yellow-mummy, blue-werewolf, green-creature from black lagoon, pink-banishe.

Fruit samurai instead of the elemental samurai like we got with Shinkenger. Instead of using lock seeds, use something else and I think it could actually work. Sets up nicely for another purple/violet ranger

Got any sentai relating to OOO?

Journey through the decade would fit with gokaiger sort of and Wizards opening theme would fit with magiranger

Fourze? Uuchu KITAAAAA!!!!!!!!!!

Probably use the zodiarts for rangers. While their enemies are based on the Olympus Twelves based on the Roman gods like Jupiter, Bacchus, Vulcan, Juno, etc.

I mean, Insects would be the obvious theme to use. It's not like Kamen Rider is based on Insects anymore.
