I like the suits a lot. I can see myself dropping lots of dough for the figuarts. Really looking forward to the sixth ranger. I'd be especially elated if the dinosaur of the sixth ranger turns out to be Spinosaurus. :)

Are we suggesting a Star Trek-esque even number theory? I know some people (*cough*Sentai*cough*) who would take offense to that. :D

If he/she is Yellow, we can look forward to interesting color reversals with the sash and yellow highlights.

It wouldn't surprise me if Green was Don lol Returning because he likes the feel of spandex on his thighs :D

If anyone deserves to return it would be Don

He was the only character in that entire series to receive any form of Character Development...

Not all that familiar with Sentai as a whole (Gokaiger was my first) but how often do old Rangers appear or old characters take on new powers?

Not often to never (Unless you're talking Power Rangers).
Kenji Ohba has been 2 Rangers, but that's just his actor playing 2 different roles, not the same character returning.

I was meaning sentai, I know they have in PR

Then yeah, I'm pretty sure it's on the never side of the fence then.

Shame, would've been fun to see him again. Though the inevitable movie should see a comical Green teamup haha
