I was trying to make the Cobra Trooper from the first Cobra box set.... I used an Air Trooper and a wave 2 Trooper (with hole in back !) seen here as Hasbro makes them: And VOILA ! .... Just switch the legs, vest/belt & head.... Instant Red symbol Trooper (I just have to paint his neck flat black...heh, red neck Trooper !) AND since the Air Trooper is "Elite" the silver symbol suits him much better: Here are some other variations you can make just by switching parts from Air Trooper with wave 2 Trooper.... Have fun & build them troops up ! ! ! .... COBRAAAA ! ! !
