"We're excited about the villains in this film" - Kevin Feige
Makes me a little more hopeful about Mads character.
Does the symbol on his head have letters comprising the symbol?
Possibly a distorted D
Maybe M and N
A C lying on it's back or U
A H
A double-bladed T
Two halves of an O
The shape is almost a mockery of the Vishanti symbol or maybe a silhouette of sorts.
