Intelligence Staff Officer Maribaron (諜報参謀マリバロン Chōhōsanbō Maribaron) is a character in the Kamen Rider Series, Kamen Rider Black RX.
Maribaron is from a noble family outside the Crisisians with feelings for Jark. She uses the yellow feather on her helmet as a dart weapon or to send messages, along with using an electromagnetic whip, breathe fire, necromancy, and energy string from her forehead used to restrain opponents. She cares for her comrades, displaying it when Lord Crisis' living heir Garonia dies in a freak accident on their watch and she attempts to cover it up by kidnapping Hitomi to take her place. Though Jark learned the truth, he allows Maribaron to take the girl to the Miraculous Valley to complete her plan. But when Kohtaro saves Hitomi, Maribaron is advised by Jark to make a false report that the princess was killed by RX. When Granzyrus arrives, Maribaron revived the spirits of 10 soldiers Kohtaro killed to finish off the other riders. She was eventually shocked to learn that Dasmader was Grand Lord Crisis' mobile body. She was killed by Crisis when she objected on his decision to have RX join them.
