Kabe no Kyojin, known in Japanese as 壁の巨人, refers to the Wall Titans from Shingeki no Kyojin (Attack on Titan). These are enormous, dormant Titans embedded within the Walls that protect humanity. They play a crucial role in the series’ worldbuilding and central mystery, later becoming key to the story’s conflict and the revelation of the Walls’ true nature. Rather than a single individual character, this term describes a collective force tied to the series’ history, politics, and apocalyptic stakes.
