Attack on Titan is like the Game of Thrones of anime because the fans could never tell if their favorite character would live to tell the tale in the next episode. Hajime Isayama’s highly acclaimed anime adaptation received unprecedented praise and fame since its inception a decade ago. After the series’ action-packed and tear-jerker ending, the fandom erupted in an unending discussion about whether their favorite character met the end they deserved. Attack on Titan came a long way from Eren, Mikasa, and Armin’s first introduction to the world to their final goodbyes. Between these two events, the audience witnessed some of the finest character development and storytelling ever to grace the anime scene.
