Other than mandarake after release, how can we order the Amazon excl version

Use a service like Tenso or hope it's one of the growing number of items that Amazon Japan is starting to ship internationally.

Looks pretty good actually. The scars on his shoulders are sculpted like they should be, not painted like we assumed from looking at the displayed prototype.

I love this. My only nitpick, and it's not with the toy, but with the actual Rider's design, is that damn ball tipped horn. I would kill to have all 3 Amazons to have Omega's horn. :lol

Item page with official pictures for Amazon Alpha is up: http://tamashii.jp/item/11480/

And the Amazon.jp exclusive includes flame effects, same as Amazon Omega, only in a different color.
