This is the pattern for the Batman amigurumi doll pictured. Included is a pdf for the doll (7 pages) and a pdf of all the stitches used for beginners.
When finished he stands at approximately 6.5 inches tall (~17cm), balances on his own and his cowl can be pulled back to reveal his secret identity!
