Titan shifters are humans in possession of the power of the Titans (巨人の力 Kyojin no Chikara?) which allows them to transform into Titans. Unlike regular mindless Titans, they are able to control their form and retain their human intelligence. It is often noted that these Titans are far more powerful than regular Titans and oftentimes display abilities unique to only them, though only nine humans can possess the power of the Titans at any point in time.
