So he's basically OOOs but as a Ranger.

Notice how the three colors are stacked on top of each other. I like.
Now show us the live action shot Mr.Toei. :)
As for the default color, would everyone agree that it is black if we have to designate it one color for organizing purposes, etc.?

After thinking it over, I think it would actually be fitting if the 6th Ranger was a Deathgalian turncoat akin to Akira. Would fit with the triple nature of the suit.

Got 2 question for you

Would you prefer Zyuoh The World be an alien or a human?

Do you want him to be a comic relief-type like Shinken Gold or loner-type like Time Fire?

It depends on how his costume is like if it changes with his heads.

Yeah, he's mainly black and his main mecha would be Cube Rhino.

TheWorld is amazing! Up there with BoukenSilver for me in the badass look category.

Too bad the Rhino (and I'm saying this very lightly because the Rhino is my favorite animal) isn't a hammerhead.

Zyu-Aku

Though the Crocodile is the 7th Numbered Cube so wouldn't that technically be his main just logically speaking?

I'm assuming rhino is his main, considering it's the centered animal on his design.
