Bertholdt

Human form

Bertolt was a rather tall and slender young man. He was the tallest of all the currently known holders of the Titan power. He had short, dark hair, brown eyes, thin eyebrows, and an elongated face. He was mostly seen in his Trainee uniform, and after he joined the Survey Corps, he wore their uniform. After his encounter with the Beast Titan, his hair appeared shorter and he wore a trench coat. During the Warriors' battle at Shiganshina against the Survey Corps, Bertolt wore a set of vertical maneuvering gear along with a collared shirt and dark pants.

Personality

Bertholdt was a very calm person and was embarrassed when someone he liked looked at him and even felt a little embarrassed, but when he was in situations where he was cornered, he took courage to fight and lost his shame.

Abilities: In his colossal titan form, he was able to burn his muscle mass in order to release a large jet of steam from the back of his neck, in cases where someone tries to cut his neck, his steam is so hot that it is capable of burning a human alive, but he has his weaknesses with this power, as he is a Titan that weighs more than 60 m, he cannot stay transformed for a long time or use his steam for a long time. His body becomes thinner as he uses more steam, capable of turning into just a 60 m skull.

Explosive transformation: The bearer can choose how he will do his transformation. He is capable of causing a huge explosion and hitting several people who are close to him, but in other cases he is capable of causing a great windstorm capable of throwing everyone away.

Colossal Titan Form

As the Colossal Titan, it possessed a very distinctive appearance and a number of unusual features. It grew to around 60 meters tall, making it roughly four times the height of any other Titan seen to date (with the sole exceptions of Rod Reiss's Titan form and Eren's Founding Titan form).

Bertholdt's Colossal Titan form was one of the most heavily deformed Titans seen in the series - he appeared to be completely devoid of skin, and his jaw and facial structure appeared to be heavily altered from his human form. He was also constantly releasing jets of steam from the surface of his body, in a manner parallel to his frequent nervous sweating. His feet were also quite different from those of a human and other Titans, as they were swollen and pillar-like. He had thin arms that were disproportionately long compared to his head, body, and legs.
