Krailoni is one of the supporting antagonists of Treasure Planet. As the only female pirate in John Silver's crew, her physical alien appearance resembles that of a gray brain and its stem, only added with a pair of arms, which serve as her only means of walking mobility (however, this does not seem to affect her services to Silver, which involve handling guns or knives).

She is voiced by Mona Marshall.


  • Krailoni seems to resemble Yzma, the main antagonist from The Emperor's New Groove.
