Firepower is the unknown quantity.
Coldblood we know at least *a little* about, from James Badge Dale himself. JBD said that he is the "muscle" of the baddies, while Killian is the brains, and Mandarin is the mouthpiece. JBD is also seen in dress uniform aboard AF1 during the attack on the plane. We know he's a cyborg in the comics, but we don't know how they plan to translate that to film, if at all.
