Atlas

Atlas is the first and most powerful Horror. He has the ability to manipulate water in all its forms. He is extremely protective of all his younger siblings. Atlas was the only Original to actually be used as a bioweapon due to a deal he struck with Vesta to protect his siblings. After Vesta died, he and Nine were placed in an experimentation facility for years until being broken out by a small group of T-2s dedicated to finishing the cure for all T-2s and Horrors, which would turn all of them back into normal humans. He then goes on a journey to find and persuade all of his estranged brothers and sisters, some of which seem to despise him for "destroying their home". Most of the originals blame and despise Atlas for the death of the head researcher Vesta, but it is later revealed to be Nine who killed her.

Appearance
Atlas, like the other eight originals, has white hair and yellow eyes, with black pupils. His hair perpetually covers his right eye, which he could have lost during a mission while the Originals still lived together in the first experimentation facility, as there may have been a glimpse of a bandage covering his eye in episode 59.

Ability
Atlas has the ability to control water in all its states, but uses it in its ice form for the entire first season. He is extremely powerful, and is the strongest of all the Horrors. Atlas is able to override Fyra's ice ability.
