Princess Devilotte de Death Satan IX, otherwise known as just Devilotte (sometimes spelled Devilot), is a character from the fighting game Cyberbots: Fullmetal Madness.
Devilotte de Death Satan IX is one dangerous princess. She and her two lackeys (Dave the scientist and Xavier the wizard) fly around space looking for people with Variant Armors so she can steal parts from them. Perhaps, all she wishes for is the VAs to add to her collection. It doesn't appear as though she is involved in either side of the dispute in the Earth Force events. She is apparently just a spoiled brat looking for something to do.
Devilotte pilots the S-008 SUPER-8, a mech designed for underwater use that resembles an octopus. The SUPER-8 is a tough mecha to fight, usually showing up near the end of the game. Its moves have names like: Red Omega, Hell Delta 1, 2 and 3, Devil X, Final O, Super Gamma, Octopus Jr. and Deathsaturn Sigma (its Cyber Ex move). Even when beaten, the SUPER-8 is never unlocked for play.
Devilotte has a crush on Gawaine, and is constantly blushing when he is near.
Devilotte appears in Super Puzzle Fighter II Turbo as a hidden character.
Devilotte also appears in the crossover RPG, Project X Zone, for the Nintendo 3DS, where she functions as a support unit. She can be assigned to any combat unit as their combo support. In the game, she is introduced into the story alongside Flynn Scifo from Tales of Vesperia in the world of Valkyria Chronicles. Devilotte demands that Flynn protect her after he introduces himself to her as part of the Imperial Knights, and offers to make him into an "enhanced fighting monster" as thanks, much to Flynn's bewilderment. The Project X Zone team then shows up to help them with the surrounding monsters. With Devilotte as a support unit, the current music may change to play her theme song "SUPER 8" during the pair unit's active turn.
Devilotte also appeared in the Japanese-only social game, Onimusha Soul.
She is also a helper in Marvel vs. Capcom: Clash of Super Heroes, and is seen in Tatsunoko vs. Capcom in both Doronjo and Joe the Condor's endings. She is seen in Dormammu's ending in Ultimate Marvel vs. Capcom 3.
