Head: Comic Pack Grunt Modified
Body: Comic Pack Zap

This is not quite an LBC, but it is very close. The Grunt head is a great sculpt but suffers from the "star of issue" concept by putting a character in a narrow situation related to the comic it was included in.

Overall, it is really simple to capture the look of the original Grunt as drawn in those early issues (and used in the cartoon as the basis for the Greenshirts) by using the Zap body. The tricky part is keeping a steady hand on a very sharp blade when cutting off the ball neck and gluing on the straight peg.
