Could we have a insect sentai if they take a break with the KR's ?

Toys.

They don't necessarily have to be on hiatus for sentai to pick up the insect theme honestly. Kamen Rider has not had a insect motif in a while and at this point doesnt really have to. We already had Kabuto and that is fine by me regardless of how good or bad the show is.

Well considering the giant robot dragon god who showed up in Dairanger to tell them to keep it down or else... I'd say they do.

So am I the only one here who hopes for a Brown Ranger in a future season?

I hope for one.

Would work a fruit-themed sentai ?

It could seeing how they made Block Animals work.

I was expecting something in the lines of Galactus/Anti-monitor-like villain.

So are we hoping that if they make a Gokaiger 10 years after movie, that they release Zyuohger, Kyuranger, Lupinranger, Patranger, and whatever next years Sentai is as Ranger Keys?

Could these be used as Ranger colors at some point, even if 2 of them aren't colors?

Brown, Rainbow, and Clear (invisible) but you can see some of the suit like the visor, collar, gloves, boots, and team logo.

Visually it seems like the primary and secondary colors they already use (red, white, blue, yellow, green, pink, black),..just look good on film.

Brown visually wouldn't really look good on film. Neither would rainbow or clear.

And how would you market a clear toy? Clear plastic? That would look odd. Has any kid ever listed, "Brown" as their favorite color? Like Red and Blue?

I'm pretty sure the reason they use the colors they do is because they look good and track well on film and stand out from the backgrounds.

Has there been Brown Kamen Riders? Also yes clear plastic.

Kamen rider is different due to it's armored designs, rather than skin tight suits.
And yes, there have been brown riders (Gridon is the first to come to mind, but I know there are others).

Impaler from Ryuki came first as a brown rider followed by Eiki and Habataki from Hibiki and Punch Hopper from Kabuto. Yes Punch Hopper is brown. A dark and a tad desaturated brown.

I was unsure whether to call Punch Hopper brown or copper. I remembered the Hibiki riders, but I couldn't recall their names, so I just didn't mention them.
Straight up forgot about Imperer, though :lol

A copper and/or bronze ranger would be cool.

Yeah, I thought Punch Hopper was dark grey at first long time ago but yep, if the figuarts and his zector are any indication his armor is of a brown hue.

It happens. :lolol

Ditto. We already have enough gold and silver rangers I think personally so a bronze ranger would be nice for a change of pace.

Kamen Rider Ketaros (had to look up the name, I always get those three confused).

What colors would you guys like to see used that haven't been used before?

I'd like to see a hot wheels-like sentai someday, but is never gonna happen.

What if they do a Gokaiger 10 years after movie, that has living Ranger Keys in it? Like a Sentai made of living Ranger Keys?

Would Turboranger be a mystic arms sentai ?

Nope. Their stuff is primarily technology based.

Did Gunmajin ever show up or get mentioned in Gokaigar? I don't see him i the Legendary war clips or in the various transformation clips for it.

Gunmajin wasn't treated as a ranger or extra hero in Gokaiger. So there's 1 of 2 possibilities that could have happened.
Either he was destroyed during the mecha fight, or he just didn't return for the great war (As he leaves Earth after Ohranger).

Where can I find the rumors of Sixth Rangers for Lupinranger VS Patranger?

In the Lupin/PatoRanger rumors thread.

Which grunt as of 2018 has the best design?
Choose only one.

Personally I choose the Podermen from Lupin VS Pat.

Grunts?
I would say the Dustlers from Denziman.

The Kuros from Toqger, hands down

Knew someone was gonna say that :lolol

I thought that Kyuuranger would be called starranger and the would have space vehilces like Megaranger.

Percentage chance we'll eventually get a 3rd season of Akibaranger?

Zero for now. Who knows maybe they will release something like a movie in the future but considering it was a promo show for sentai figuarts later on by season 2 pretty much I would not count on it.

Would make sense a gryphon mecha in some feline/cat-themed sentai ?

Ehh, don't see a problem with it since gryphons are cats with an eagle's head, wings, and talons.

I have to admit. I find it disappointing when 1 character can be Lupin and Patren X. I mean seriously, why can't they follow the examples of Go-Onger and Go-Busters? I may have misread the scans but I was hoping 1 character to be Patren X and another character to be Lupin X, I guess it is not gonna happen. There goes my excitement for Sixth Rangers, ruined :(

Given that we already have 6 face actors in the show and that the sixth rangers are meant to shake up the status quo; I think Lupin/Patren X is going to be similar to Shurikenger, a character who we'll only see in suit, showing up from time to time and being this elusive enigma for both teams.

Sure, why not? Or you can have a Sphinx or a Nekomata as the Sixth Ranger.

As for the main team:
Nekoranger Red: Lion
Nekoranger Black: Panther
Nekoranger Blue: Jaguar
Nekoranger Yellow: Cheetah
Nekoranger White: Tiger
