Attack On Titan Cliffhanger Sets Up Marley's Counterattack Attack On Titan's fourth season has come to a close, and while fans will have to wait until 2022 to witness the final adventures of the Survey Corps in the anime, the latest episode gave us quite the cliffhanger as Marley launched their counterattack against the island of Paradis and Eren Jaeger himself. With Eldia in disarray as Eren and his Jaegerists have overtaken the military and are attempting to enact the "Euthanasia Plan", there are now three sides to the battle whose outcome will be sure to change the world of the anime forever.
