Professor Tanner is the scientist in charge of the global militia project and the creator behind the supers powers used by its members. His age, goals, and motivations are unknown and he rarely shares anything about himself. The character is a complete loner with only a few other characters interacting with him on a regular basis. Tanner functions as a mastermind behind the militia side of the conflict and his actions can tend to be morally questionable. He will ultimately serve as one of the biggest cogs driving the conflict.

Tanner is very blunt, calm, and often times cold in his mannerisms. He will on occasion express concern for other characters and can emit some slight moments of compassion. He fulfills the role of an antagonistic character while still being able to show a softer side to himself.

Actor's going for Tanner should be able to have a calm and tactful performance for Tanner. Tone of voice matters more than the range but it shouldn't be too young or high pitched.
