Voice:

We are looking for a performance similar to Daniel Bruhl's portrayal of the character. A deeply injured voice, cold, calculating with a Sakovian accent.

Character Description: 

Colonel Helmut Zemo is a Sokovian citizen who turned terrorist mastermind who sought revenge against the Avengers after losing his family during the Battle of Sokovia, becoming obsessed with defeating and destroying them. Knowing that he was no match against the Avengers, he instead planned to have them destroy each other by first framing the Winter Soldier for the assassination of T'Chaka, causing Captain America to defend his friend from the world. This action caused the Avengers Civil War in which Iron Man led a manhunt for the Winter Soldier and Zemo allowed Iron Man to discover that the Winter Soldier was also responsible for the deaths of his parents. With the Avengers in ruins, Zemo tried to commit suicide but was stopped by Black Panther and handed over into the custody of Everett Ross for his imprisonment.

Personality: 

Helmut Zemo was a member of a death squad of the Sokovian Armed Forces that managed to build a happy family despite the nature of his job. However, the war between the Avengers and Ultron ended up with the death of his whole family, and he became consumed with so much anger and hatred that he allowed both to cloud his mind. Despite knowing that the Avengers were not the villains of that war, Zemo nevertheless held them responsible. Without any means or resources to take the powerful group head-on, he wished to destroy the Avengers from the inside, ensuring that they are forever crippled, if not dismantled outright. While he is a very vengeful man, he is actually more the ultimate personification of manipulation as he is able to carefully plan and execute all the steps required to manipulate the 'pieces' involved to do his bidding, whether if said 'pieces' realizes it or not. His use of psychological warfare was so brilliant that he was able to compensate for previously unaccounted factors--death of T'Chaka and Black Panther joining the fray, and turn these seemingly rogue factors into further his plans.

However, despite his relentless attempts at trying to destroy the Avengers, Zemo is ultimately not without a conscience. He first tried to interrogate a HYDRA officer, but stated that if he didn't get the mission report from the officer, then he would resort to more violent means though he didn't enjoy using said means. Zemo also sincerely apologized to T'Challa for accidentally killing his father T'Chaka, and he even opened up to him about why he wanted the Avengers destroyed. This caused even T'Challa, a man who had wanted Zemo's death the most, to sympathize with his current situation, and even spare him, as he realized that revenge would have completely consumed and destroyed him, as it did with Zemo.
