For the 25th Anniversary of the line, Hasbro re-created many of the classic Joe & Cobra characters, giving them a fresh and modern look. As you can see the designers didn't stray too far from his classic A Real American Hero design. Sadly I no longer own any of my childhood Joe toys so there won't be any comparison pictures here.
The 25th Anniversary version of Storm Shadow was first offered in a 5 figure box set alongside Cobra Commander, Destro, the Baroness and a Cobra Trooper. He was later packaged on a blister card with art work very reminiscent to his ARAH packaging.
Storm Shadow is one of the most iconic Cobra characters and I personally love the update he received here. Not hard to find on the secondary market, or expensive; this is a figure that belongs in your modern Joe collection.
