If you find a couple of blue pieces that look like claws or legs they're his too. He was a homage to Black Zarak (who was a remould of Scorponok), and as a kid, Double Punch played in my collection as my Action Masters Scorponok. He's a fun toy (and also sells for quite a bit these days since he wasn't available in the US or Japan. Yours is in good condition, and if he has working action arms and the aforementioned blue bits you could get up to a couple of hundred dollars for him.)
