None as of the moment. Even with Attack on Titan's popularity for nearly the past decade, manufacturers continue to just focus on making statues of Eren, Mikasa, and Levi. Only Sentinel has released 4 characters from Attack on Titan, 1/8 statues of Eren, Armin, Levi, and Erwin. However, you'll have more luck getting many of the characters in Nendoroid form as Eren, Mikasa, Armin, Levi, Erwin, and Hange have existing Nendoroid versions. A Nendoroid of Reiner has also been announced to be in production soon.
