The Guardian in Slendytubbies 3 has a complex, evolving personality, starting as a dedicated observer who grows attached to the Teletubbies, displaying bravery, intelligence, and empathy, but later devolves due to trauma, experiencing hallucinations and PTSD from the Infection, with choices affecting his journey from determined investigator to mentally fractured survivor or even infected being.

• Observant & Attached: He initially monitors the Teletubbies as subjects, developing a strong bond, considering them friends despite their unawareness, which makes their suffering deeply affect him. • Brave & Determined: He actively seeks answers about the Infection and his own species' origins, showing courage in dangerous situations. • Skilled & Intelligent: He's shown to be adept at lockpicking and survival. • Traumatized: The horrific events lead to severe PTSD, hallucinations (seeing the main Teletubbies), flashbacks, and survivor's guilt, heavily impacting his mental state. • Choice-Driven: The player's decisions shape his personality, allowing him to be rude/aggressive or empathetic, and ultimately determining if he succumbs to infection or finds a different fate. White can be adorable when he's happy, can even be secretly flirtatious.
