The Colossal Titan is one of the main antagonists in Attack on Titan. The largest Titan ever encountered, having first appeared in the Year 845 outside the District of Shiganshina. It is approximately 60 meters tall with a physical appearance resembling a humanoid being without any skin, exposing muscles and connective tissue. In addition, it has not shown any interest in consuming humans. It appears suddenly and without warning in a flash of lightning, and disappears in a similar manner in large clouds of steam, which constantly pours from most parts of its body. It possesses the ability to release this steam at high pressure to defend the weak point at the base of its neck. Possessing a physical mass far larger than any other known Titan, it was easily able to kick down the Gate into the District of Shiganshina and thus is partially responsible for the fall of the Wall Maria. It displays cognitive recognition when it appears before the District of Trost in the year 850, as after kicking down the gate into the district, it destroys the cannon artillery atop the wall so that the invading Titans would meet less resistance. Later it is revealed that the Colossal Titan is Bertolt Hoover's Titan transformation. The revelation of his true identity illustrates the moral uncertainty of the series.
