Professor Kimda is a Kryptonian scientist, living in Kandor. He had been Jor-El's roomate in college on Krypton, and became a good scientist. After Brainiac shrunk and bottled Kandor, he would use his telescope to spy on Brainiac and decipher the uses of his machinery. When Superman first entered Kandor, Kimda showed him his findings and helped him to escape and reenlarge the Human cities. However, before Superman could enlarge himself, Kimda intervened, and enlarged Superman instead with the last of the enlarging ray. ("The Super-Duel in Space")
