Mr. Whatsit
Mr. Whatsit is the sinister alter ego of Henry Creel (also known as Vecna or One), who appears to young children in Hawkins, Indiana, in Stranger Things Season 5 under the guise of an innocent imaginary friend. Inspired by the character Mrs. Whatsit from Madeleine L'Engle's A Wrinkle in Time, this persona allows Vecna to manipulate vulnerable minds by presenting himself as a protective figure warning them of "monsters" while secretly luring them into the Upside Down to serve as minions.
