|This article is about a/an villain in Power Rangers Lost Galaxy.|
Hexuba serves as a sorceress for the evil Captain Mutiny and hid in an abandoned shop in Terra Venture. Captain Mutiny sent her to destroy the Rangers by trapping them in a dream dimension and she managed to get all but Mike Corbett inside using enchanted flowers. Mike, barely managing to stay awake, made it outside her flower shop and she teleported him in to confront him face to face. Hexuba restrained Mike with an energy stream, but he was able to deflect it with a mirror, causing a chandelier to smash her crystal ball. With her dream spell broken, the Rangers were able to destroy Nightmare and escape. Hexuba then promised an angered Captain Mutiny that she wouldn't fail him again.
Next, Hexuba cast a spell that resurrected the Rangers fallen enemies to wear them down and destroy them. As the Rangers faced the monsters one by one, Kai followed their trail back to Hexuba's Mansion where he engaged the evil sorceress. During the battle, Kai managed to get ahold of Hexuba's new crystal ball that she used to control all of her magic and tossed it into her cauldron, destroying the crystal ball and breaking her spell. The effects also destroyed her mansion. However, Hexuba herself survived and teleported to Terra Venture where she absorbed the souls of the destroyed monsters. The Rangers Lights of Orion Power-Up Mode attack had no effect on her and an attack by Leo as the Red Armored Ranger only made her stronger and Hexuba grew giant. The Rangers summoned the Galaxy Megazord and Defender Torozord to fight her, but were unable to destroy her and were defeated. Leo then summoned the Stratoforce and Centaurus Megazords who attacked Hexuba and beat her up before the Centaurus Megazord hit her with its laser cannon. With Hexuba weakened by the Centaurus and Stratoforce Megazords attack, the Galaxy Megazord destroyed her with a charged strike from the Galaxy Megazord Saber.
- Hexuba's "powered up" form includes Hardtochoke's head on her left shoulder, the head of a blue and red Asura monster (unused in this series) on her right shoulder, the faces of Icy Angel, Crumummy, and Skelekron on her left arm, Freaky Tiki and Maronda's faces on her right arm, and Rykon's face within her stomach (only Rykon lacked a jewel in its mouth).
- Hexuba speaks in a Russian accent, similar to Jara from Big Bad Beetleborgs. This is due to the fact that the same actress voices both Jara and Hexuba.
