This article is about a/an kaijin in Kamen Rider Black RX.

Flarmiglarmi is a jellyfish-like alien parasite capable of teleportation, extending the tentacles on his torso and back, and has a pair of whip arms that can emit electric shocks and blasts. Sent to obtain the G Crystal that was stolen by a rogue Crisisian scientist and his daughter Kirara, RX drove him away as Kirara learns the G Crystal is found by Shigeru and Kengo. Flarmiglarmi later enters Kirara's body, getting the G Crystal from Shigeru as Kohtaro arrives. In spite of warning Flarmiglarmi the danger the G Crystal poses for both worlds, RX is forced to fight him with Acrobatter before killing him with the Revolcane. The explosion from his destruction also destroyed the G Crystal and the machine it powered.
