Bertholt Hoover

Bertholdt Hoover (ベルトルト・フーバー Berutoruto Fūbā) was a graduate of the 104th Cadet Corps and a former member of the Scout Regiment. He ranked 3rd in his class, and was described by others as a weak-willed and quiet person. He was rarely seen without Reiner Braun, his close childhood friend, both of whom originated from an unknown area which he refers to as his hometown.

Along with Reiner and Annie Leonhart, he was a person that possessed the ability to transform into a Titan. As the Colossal Titan, he was one of humanity's greatest threats; in the year 845, he used his power to help Reiner breach Wall Maria and infiltrate the military for unknown reasons.
