Intro. Mr. Whatsit in Stranger Things Season 5 is actually the main villain, Vecna (Henry Creel/001), disguised in a friendly guise to manipulate and lure children, particularly Holly Wheeler, into his trap, drawing inspiration from the character Mrs. Whatsit in A Wrinkle in Time. He appears as a dapper, comforting figure with a red tie and warm tones, mirroring Mr. Rogers, but is secretly harvesting the kids to achieve his sinister plans for Hawkins.
