Mr. Slate

Mr. Slate is Fred Flintstone's perpetually exasperated boss at the Bedrock quarry, embodying the classic gruff employer archetype in the Stone Age world of the Flintstones. He appeared in Charlton's comics adaptations of the beloved Hanna-Barbera animated series.

Few characters embody the gruff, put-upon boss archetype quite like Mr. Slate, who made his comics debut in Charlton's Dino #1 in 1973, stepping into the Bronze Age alongside the beloved Bedrock crew. Over a roughly twenty-year run across titles like The Flintstones and Pebbles and Bamm-Bamm, he shared the prehistoric pages with Fred Flintstone, Barney Rubble, Wilma, Pebbles, and the irrepressible Dino himself. His catalog appearances may be modest, but as a fixture of that iconic Flintstones world, he's a satisfying find for any Charlton collector chasing the full Bedrock roster.
