White, also known as The Guardian, is the main protagonist in the horror game. Slendytubbies lore explains that artificial Teletubbies, created by ancient human technology, are infected by a virus spread through Tubby Custard by the rogue Al Noo-Noo, turning them into monstrous 'Reborn' creatures, leading to an apocalypse where the guardian, military, and survivors fight back against the horde, with the core story focusing on the corrupted Tinky Winky and the quest to understand and stop the infection. White uses a yellow chainsaw as a weapon later.
