The Walrider

The Walrider's powers and abilities

As it is composed of nanites, it is nearly invisible to human eyes, only showing a faint black aura, unless it comes into very close proximity to the player. Miles can only see it clearly through the night vision mode on his camcorder. Despite having no actual bones, muscles or internal support structure to speak of, the Walrider's nanites are capable of immense physical strength, and it is the most physically powerful entity in the game. It can easily overpower any Variant, including the large, muscle-bound Chris Walker, as shown in the Underground Lab when Walker is brutally murdered. The Walrider is relentless in its pursuit, while doors will slow its progress somewhat, it is capable of going underneath them. It is extremely difficult, if not impossible, for the Walrider to lose track of the player in a chase scene, only stopping once the player passes through a decontamination gate, which the Walrider cannot pass through.
