The Chilling Counselor was once a well-meaning guidance counselor at Bingham Creek High, but during the prom night summoning, they were possessed by a demonic entity that amplified their desire for control. Using their position of trust, they secretly organized students into a cult dedicated to hell's hierarchy, orchestrating rituals that worsened the invasion. Their transformation completed as the portal opened, turning them into a permanent vessel for demonic influence.

The Chilling Counselor possesses a physically imposing yet eerily calm demeanor, with skin that feels cold to the touch and emits a faint, mist-like aura. They can manipulate shadows and whispers to influence others, causing paranoia and loyalty shifts among survivors. Their presence weakens holy symbols and amplifies demonic energies, making them a persistent threat on the battlefield. They are immune to conventional weapons but vulnerable to artifacts tied to their human past, such as old yearbooks or prom memorabilia.

The Chilling Counselor acts as a manipulative force that corrupts survivors and strengthens demonic entities by recruiting followers for hell's hierarchy, influencing key events by turning students against each other and facilitating the spread of possession.
