Favorite Basic Mecha is Shinken-Oh.

I love how the origamis turn into animals, but also how they fold to form the body parts.

Actually, all of the Shinkenger mechas are my favorite. Gokaiger's comes in second.

The thing with Shinkenger is the balance between combination of different origami and how it's placed.

It's also pretty creative in what you can do when you combine Kabuto, Kajiki, and Tora. They combine to form a weird bird thing and then combine again to make an super form or something.

I personally like Samurai Ha-Oh because it's HUGE!!!! Even though it's Daikai Shinken-Oh in Ushi Origami, I still think it's cool.

Oh yeah, Kyoryu Samurai Ha-Oh is actually the true ultimate form when you add the giant sword to the mix.
