Kubal was a middle-aged man that had white hair and a square jaw. As the commander of the Military Police Brigade, he wore black military police attire.
Personality
Kubal was a cruel man who stopped at nothing to achieve his goals. He did not value the safety of his men and, in retrospect, tried to killed those in his way such as Eren and Mikasa.
Abilities
Kubal was seen giving orders to the new recruits, displaying some level of authority.[1]
It was also revealed that Kubal was in fact, another Titan shifter, his Titan form being none other than the Colossal Titan.
The Colossal Titan's height is stated to be 394 feet in the movies
Kubal was the Commander of the Military Police Brigade in the live-action movies; whereas in the manga, that position belongs to Nile Dawk, who does not exist in this continuity.
He was also revealed to be the true identity behind the Colossal Titan, replacing Bertholdt Hoover, who is not portrayed in the live-action movies either. Also, his Titan form was 120 m tall, twice as big as the Colossal Titan from the original manga and more in the likes of Rod Reiss' Titan form. However, in the movie novelization, Kubal's Titan form is said to be 60 yards tall, much closer to the height of Bertholdt's 60 m Titan form in the original manga.
Due to his attempts to get Eren executed for considering him a threat to humanity, he also effectively replaced Garrison Captain Kitz Woerman (though in Kubal's case it was just a facade).
