I have the original SIC (Super Imaginative Chogokin) TaJaDol Combo of Kamen Rider OOO (pronounced O's) in my collection, but this version looks way cooler.
This figure represents when Anhk uses the OOO belt-- with the TaJaDol Combo-- to become Kamen Rider OOO. It even features Anhk's forearm and hand (the only parts of his true form that's left of him).
This will be a Tamshii Web exclusive, so expect it to run well over $100 if you're looking to pick him up outside of Japan.
He'll be released in October.
