We were lucky here in the US as Hasbro released Bear Fighter as part of the "regular" line. In Japan Bear Fighter was a white box Zoid. He is an interesting build and one of only two Zoids that can walk on either two or four appendages. (The other being Gungyarados) He is an interesting build, displays well, and is a fun addition to any collection.
