Soulless (Kingdom Hearts Chronicles)

Soulless (Kingdom Hearts Chronicles)
Soulless are forms that the inhabitance of Splatoon take when the Darkness consumes them. They are called Soulless because unlike other victims of the Darkness, Inklings and Octolings technically lack "Hearts" and instead have "Souls."

Behavior
Soulless are extremely aggressive beings. Like the Heartless, they seek and devour other Hearts and/or Souls. They also are unable to be controlled, and will attack anything they see, including the Heartless, and sometimes even each other. This is because they are unable to think at all, resulting in their aggressive behavior. Unlike Heartless, Soulless can be freed from the Darkness using Light, which can kill the Soulless themselves if exposed for too long. Roxas uses the Light to rescue Agent 3 from the Darkness.

Weakness
Soulless are weak towards the Light, as it causes them to burn severally. When a Soulless is exposed to the Light for too long, it will die.
