Mass Effect, Udina © BioWare/EA.
Note: Now, I'll just say before some smartarse does; this is not actually Udina, it's his clothes, hair and face, but the head is actually wrong. The reason for this is simple, due to the way that BioWare made the morphing heads, there's a single head marked as "custom," this is the head that is apparently used to morph to different shapes. In this way they can get numerous heads for random NPCs instead of making one for each NPC (saves resources and time). Particular NPCs which are modelled after a particular person/actor/model are made separate from the custom one. Hence the Illusive Man, Anderson, Shepard, etc., etc., are all available to me.
This is basically just to give people an idea what Udina looks like, but is likely more useful as a clothes reference. Which probably isn't going to be terribly useful.
