Well, I for one am glad they did. For the most part, this line has been more or less very realistic takes on the characters. So I'm glad to finally see a bit of fantasy tech making its way into the line. I think little bits here and there like Bludd's arm will help pave the way for something more outlandish like Destro. I'm still stumped on how they will handle him. Classic 80's bare chest and red puffy collar wouldn't fit all that well with the rest of the line, but a guy in a suit would be boring too. I think Bludd (and Zartan for that matter) is a great balance and it gives me hope Destro will be done right too.
With Baroness coming soon, that gives us 3 of the 4 I consider to be the Cobra High Command (CC, Destro, Baroness, and Bludd)
