Plus last I checked being thrown around on wires firing laser beams isn't a martial art.

Yes it is, it's called Wire-Fu. :p

For a martial arts themed Sentai, I want a Sumo Wrestling one. :lol

Yeah, yeah, yeah... ;)

Let's remix Battle Fever J with G Gundam.

A fighting style and Ranger for each nation!

What about a cyborg motif ?

Yes. Yes. This. Hopefully just as amazingly over he top as G Gundam too.

Weren't the first few sentai teams cyborgs? It'd be interesting if they went back to that...

If toei bring back the high school student based motif ?

I would love to see a Music themed sentai, with TRUMPETS, guitars, drums, harps and all of that stuff, but especially TRUMPETS!!!!!!

I doubt they will use a western themed in super sentai.

I think a sports theme can work.

Red - Baseball
Blue - American Football
Green - Tennis
Pink - Cheerleading
Yellow - Soccer

Other rangers:

Gold - Jousting
Black - Golf
Light Blue - Ice Hockey

Baseball is popular in Japan and is view as America's past time sport. So the idea can sell well in both in Japan and America.
