Please help I.D. Legit or KO?

Hey guys, my bro recently came into possession of this little bugger:


It looks like it's Metalman from Microman:

However, it doesn't have any markings that I can find. And the place where it looks like there would be a marking is blank:

So basically, is this a KO, or a legit Microman? The plastic feels sturdy, and the lower legs might be diecast. However, it came in a lot of GoBots and Transformers, so I have my doubts. Were these guys released in some other format in the U.S.?
Finally, what are these guys worth, and what's their rarity?
