Brainy is the village intellectual who's not afraid to share his "wisdom" with his fellow Smurfs, even though it usually results in his being booted to the village limits or whacked in the head with a mallet. He is also a very prolific author of many books, usually with his name in the title, and he is Papa Smurf's apprentice and assistant in his laboratory. He is easily identifiable by his glasses and his books.
