Attackens

Attackens are a fictional species originating from the "Attack on Titan" manga and anime series. They are large, humanoid creatures that exhibit a terrifying and relentless behavior towards humans, consuming them without apparent reason. Their primary characteristic is their immense size, ranging from several meters to over fifty meters tall, and their powerful, muscular physiques. Attackens possess a striking lack of intelligence, acting primarily on instinct and a drive to prey on humans.

Physically, Attackens have a distinct, often grotesque appearance. Their skin is typically pale and leathery, and they lack discernible genitalia or internal organs visible from the outside. Their facial features vary, but often include exaggerated mouths filled with sharp teeth and vacant eyes. They do not appear to require sustenance beyond the consumption of humans, and their regenerative capabilities are notable, allowing them to quickly recover from injuries that would be fatal to humans.

The origin and true nature of the Attackens were a central mystery throughout much of the "Attack on Titan" narrative. Initially believed to be mere monsters, their existence was later revealed to be intrinsically linked to the history and powers of the Eldian people and the nation of Marley. The term "Attacken" itself is a localized name used by the inhabitants of the walled cities, and the creatures are more formally referred to by other names within the series' lore. Their primary purpose within the story is to serve as an existential threat, forcing humanity to develop advanced military technology and strategies for survival.
