Rumdar is a Pakled who boards the USS Cerritos in 2381 posing as a defector seeking asylum, and whose hopeless spying ends up exposing a plot to bomb Earth.
Rumdar appears in The Spy Humongous, in the second season of Star Trek: Lower Decks. While Captain Freeman tries to negotiate on the Pakled homeworld, he comes aboard claiming asylum and is shown round by the senior staff, who see through him at once.
His espionage is a string of mishaps: he photographs his own foot, dazzles himself with the camera flash and finally blows himself out of an airlock, from which he has to be rescued.
Returned to Pakled Planet, he is tricked by Freeman into blurting out the real scheme, a plan to smuggle a Varuvian bomb to Earth. His image is seen again in the recap that opens Grounded. Rumdar is voiced by Rich Fulcher.
