History
This type of titan displays a strange kind of intelligence, They do not mindlessly attack humans or try to kill them; they simply run away from them and cause damage in important areas---how this type know where to attack is still a mystery as the titans themselves.

After the Colossal Titan's second attack, the titans invaded the inside of Trost and the soldiers and human forces had to take action. A deviant type appeared running quickly (which is unusual for a titan but is present in many Deviant titans) heading for a large group of citizens which were blocked by the large package dragged by horses was so strangely fast that the soldiers couldn't reach until Mikasa appeared and killed it before he reached the people. Almost all the soldiers from the walls went beyond the walls to find Eren´s house, but in the way a deviant type suddenly appeared running. Armin and another soldier are forced to fight him cutting his tendons of his foot making him fall and stabbing it on the neck.
