Medicom Real Action Heroes (RAH) Ultra Seven
Always felt that Ultra Seven's back (area just below the mask) seems rather unfinished, like something's missing
Ultra Seven is actually a soldier from the Land of Light in the Nebula M-78 system and a humanoid but I don't remember seeing ribs on his back. Not sure what Medicom is trying to do here because Ultraman Ace had similar strange anatomy.
Ultra Seven's most distinctive feature - his Eye Slugger: The crest on Ultra Seven's head can be detached and used as a throwing weapon. This is Ultra Seven's most well-known weapon, and possibly the most famous of all Ultra attacks.
