|The Venture Bros. character|
The Incredible Mr. Brisby
Li-Li was the "companda" to Roy Brisby, having been won from David Bowie in a trivia contest some time in 1980 or '81. The panda milk she produces apparently has a something of a preserving effect on Brisby, though not enough that he doesn't seek a clone.
In the same episode as her debut, Li-Li is recaptured and taken back to Bowie by the mercenary Molotov Cocktease.
