Jeremiah Gottwald (ジェレミア・ゴットバルト Jeremia Gottobaruto?) is an elite Knightmare Frame pilot deeply concerned with the maintenance of Purist supremacy within Britannian society. He is somewhat overconfident and passionate about furthering his goals, both qualities that tend to make him rash and impulsive in battle. He was formerly a part of Empress Marianne's guard, and he is deeply affected after failing to stop her assassination. Jeremiah is disgraced after failing to get Suzaku Kururugi to his trial when Lelouch, as Zero, uses his Geass to compel Jeremiah to help them escape. His impatient and impulsive action leads to his quick defeat at the hands of Kallen Stadtfeld, who has recently acquired the Guren Mk-II. He is officially listed as killed in action at the battle of Narita because everything suggesting otherwise was lost along with his Knightmare's signal. Jeremiah is subjected to a number of experiments by the scientists, now under Prince Schneizel's patronage, who enhance his body with various cybernetic devices, such as a neural interface and a cybernetic left eye.
