>>9581976I just opened my Mezco Conan to check this and for the most part his accessories work fine. Only the dagger, with it's super tiny handle, and the shield, seem to have issues working with the Legions. Everything else, even the strap, work just fine with the 1.0 figures at least. Some Legion accessories may stretch some hands, making it harder to hold Conan's slightly smaller grips. But that can affect some Legion weapons too, because those weapons vary in grip size to a crazy degree.
Heck, Conan himself isn't too small compared to the Legions. Though he is certainly out of scale seeing as he's supposed to be a 7" plus unit of a barbarian.
Mezco just announced a Barbarian accessory set with a few more weapons and some nice looking soft goods, so I'm fully expecting them to work with the Legions (except the heads anyway). Total with shipping came out a bit steeper then I hoped, but I've seen some soft goods alone reach similar prices so I had no issues going for it.
