Originating from Hajime Isayama’s legendary manga and anime series, Shingeki No Kyojin (Attack on Titan) has inspired countless memes ranging from the terrifying Colossal Titan peaking over Wall Maria to the 'Sasageyo' salute. The series’ heavy themes of freedom, betrayal, and giant monsters provide a rich landscape for internet humor, often focusing on Eren’s intense expressions or the sheer absurdity of Titan designs. Used primarily to express sudden dread, overwhelming obstacles, or dramatic plot twists, these memes have become staples in the anime community since the show first aired in 2013 and continued through its massive cultural finale.
