Mondo may refer to:
1. KAOS agent and self-styled great artist who uses Rex Savage's explosive paint to paint paintings that are actually time bombs used to destroy government buildings where information on KAOS is being held. Mondo seems remarkably sanguine about the fact that his works of art are destroyed along with the buildings.
2. Another KAOS agent, henchman of Miss Valerie, who follows Maxwell Smart back to his apartment to retrieve part of an explosive formula contained in a talking doll which Max inadvertantly took from Miss Valerie's School for Expectant Fathers.
