Zeke Yeager was the former Captain of Marley's Warrior Unit. He was a very intelligent and curious man. He displayed the traits of a leader, giving orders and telling other people, sometimes even Titans, what to do. He also seemed to be a cold, ruthless and sarcastic individual, though not explicitly sadistic. However, in spite of Zeke's savage tendencies, he had been shown to take pity on the citizens living within the Walls.
