[Kamen Rider Lucha]

What I've noticed is that since Gekiranger (arguably since Dekaranger), Sentai series seem to be a blend of two concepts.

Gekiranger = Kung Fu + Animals
Go-Onger = Vehicles + Animals
Shinkenger = Samurai + Origami
Goseiger = Angels + Natural Elements
Gokaiger = Pirates + Space
Go-Buster = Spies + The Internet (+ Animals?)
Kyoryuger = Dinosaurs + Samba/Brazilian Culture
Tokkyuger = Trains + Rainbows


So with that in mind, I propose a few concepts:

Cowboys + Planets (incorporate Roman Gods as needed) - It could be like The Magnificent Seven, with various badass cowboy archetypes from different towns (or in this case, planets) assembled to fight whatever evil organization.

Universal Monsters + Musical Instruments - I just want to see a sentai team composed of members of a rock band and influenced by classic monsters like Dracula, Frankenstein, Wolf Man, The Creature, and Bride of Frankenstein. How rad would that be? If Kiva can tread in this territory, I have no doubt Toei could do a sentai based on it.

Sports + Animals - Each member is based on a different popular sport, and their robots are called Mascots. Boom.

Medieval Knights + Insects - Combining two of the most sought after concepts. I feel like there's a natural relationship between Knights' armor and insect exoskeletons.


I think any of those would be badass entries to the franchise that still work within the boundaries of the genre.
