KAOS agent in charge of KAOS's headquarters in New Jersey.

Like all KAOS agents, Belasco is an opera lover. He is also a fan of the opera singer Rosa La Costa. This weakness allows Madame La Costa - who happens to be a CONTROL agent - access to the building under the guise of a performance so that she and her fellow agents Maxwell Smart and 99 can rescue Professor Phineas Pheasant who is being held captive there.

Portrayed by Henry Brandon [Episode #113: "Pheasant Under Glass"].
