Exactly.

Like, I'm being serious here. Why Ninjaman? He's not as interesting as Gokaiger makes him seem...

He did hook up Ninja Blue with his seiyuu career post Kakuranger.

That's pretty much the same thing I thought as well.
Ninjaman was not annoying, like Zuban in Boukenger, but he's not that interesting either.

i dont know their mentor be cat or hamster

Gokaiger did nothing to make Ninjaman interesting. Ninjaman is interesting because of who he is and that he defies the gods in KakuRanger. Plus, is far better than later sentient robots like Daimajin, GaoGod, Zuban, and GoseiKnight.

I don't know if NinjaMan is technically a robot....

So I heard a rumor that we will get 3 members and each member will have 2 suits of different colors. Thoughts?

I wonder who is the Head-writer of Ninninger?

And

Ninninger obviously have a ninja theme but what is another theme add to ninja?

For example

Goseiger, Angel Card

Gokaiger, Anniversary Pirates

Kyoryuger, Dinosaur Battery

ToQger, Imagination Train
