There are a lot of figure they can do multiple versions that would possibly sell. There are three versions of Cobra Commander that could sell (hooded, battle helmet, and Fred armoured Cobra Commander). Plus, some others. Personally, I want the Version One Snake Eyes the most. To me, he is the best design that would translate well the the 1/6th format. He a lot of textures and real world elements that to me would look great.
Three yes, but not those three. The hooded and Battle helmet from the cartoon should be the same figure with swapable heads. The armored is another possibility. But I think the Bradstreet inspired Cobra Commander could sell well too.
