Wall Titan

The Wall Titans (幻の巨人) are unusual kind of Titans that make up the Walls that protect humanity. They are first revealed when the Female Titan tried to climb Wall Sina to escape from Eren Yeager and the Survey Corps. The lack of sunlight inside the Walls renders them immobile.

Appearance
The Wall Titans are similar in appearance to the Colossal Titan, in that both their surfaces are covered in primarily muscle tissue. Their exact height is not known, but seeing as they make up the walls, they must be extremely tall.

Abilities
It is implied that Wall Titans have the ability of using their crystallizing powers to create massive walls. Their exact motives for doing this are unknown.
