G.I. Joe: Retaliation Official Movie Prequel #4 (IDW, April 2012) is the final chapter of the prequel miniseries to the G.I. Joe: Retaliation film, written by John Barber with art and a Cover A by Salvador Navarro. Storm Shadow leads his Red Ninjas in an attack on NORAD that threatens to cripple America's national security, and only Snake Eyes and Roadblock can stop him — if they can put aside their differences in time. The back cover carries a Popeye house ad, and its barcode block confirms this copy as issue #4 with the Salvador Navarro cover. This copy is graded NM-, a sharp copy with minimal wear. Bagged and boarded. Ships in a Gemini-style mailer with cardboard stiffeners. 30-day returns. Buy with confidence!
