The Fear Factor – A mysterious, shadowy entity and the central antagonist of the series. The Fear Factor thrives on fear itself, sensing intense emotion from the main characters and choosing to intervene directly by dragging them into a shared mindscape. There, it twists their deepest anxieties into horrifying, mutated monsters meant to break their spirits. But The Fear Factor doesn’t want them gone — it wants them hollow. Each time a fear is left behind, it absorbs it, growing stronger while the kids slowly lose parts of who they are.
