Diondra (ディオンドラ) is one of Gadess' key Gyandlar lieutenants and very much buys into his cause. While she comes across as a electro-whip wielding psycho bitch she can have a softer side, once getting along briefly with Tough Trailer, though not to the extent to justify the image to the right. She was often placed in charge of the Devil Satan 6.

Diondra was one of Gadess' key lieutenants when the Gyandlar mothership arrived in orbit above Cronos when they detected the Hyribead on the planet. Rising Storm - the Fighting Style of Justice! After Grujios and the Devil Satan 6 were repeatedly defeated by Rom Stol and his allies while trying to find out more about the Hyribead, Diondra was given a chance to impress Gadess. She enlisted Zagam to trap them at Cronos' north pole. However, he flaked when he noticed Leina Stol resembled his late love Elura and was destroyed by Kenryū. Hot Fight at Absolute Zero! Tired of failure, Gadess then assigned Diondra and Grujios to work together with Kirai's old enemy Mizuchi, but the latter was killed by Baikanfu. The Rock People and Mizuchi the Mysterious Dragon She led the attack on Rury's dojo along with Garudi when Glovine drew Blue Jet away for a duel but he returned in time to help Rom drive them off. Jet! Defeat the Double Death Blade! She then employed Kina and Koron, the children of Jingi (a Gyandlar captain slain by Rom) in an attempt to draw his party towards a super-hot volcano. Even though they formed Jingi Mark 2 and Rom was generally reluctant to kill the pair the plan still failed. Burn and Run, Brother and Sister Warriors! Reworking the Guilder Brothers as Giant Guilder was no more successful. Sending Love to the Horizon.
As a result she found herself benched for a while by Gadess; when she suggested Lord Pylon might know about the Hyribead it was Grujios who was given the mission of finding out. Death in the Demonic Castle in the Sky After Grujios' disappearance she took a more prominent role. It was her idea to use Nerve to control the population of Cleo City, though the captain was eventually killed by Baikanfu. The Heart of a Protecting Angel She then led excavations of a reported Hyribead location, instead discovering Rockdon. Diondra forced Java to control the beast on her behalf and had Baikanfu on the ropes until the fight uncovered Rockgiran, who fought Rockdon until the pair returned to their sleep. Rockgiran versus Rockdon Along with Garudi, she led a head-on assault against the Machine Robo city Emerald City, though they were forced backed by the sheet number of defenders. Gather All Machine Robo
While Grujios was no longer around to get in her way she soon found herself falling out with Garudi as they competed for Gadess' favour. While he was mining fire crystals to melt a frozen lake next to Emerald City she took a more direct route, capturing Apollo Robo and using him to discover an underground Machine Robo base; however Garudi soon arrived and bombed the lake anyway, leading to another Gyandlar defeat. Cross Rock's Great Prophecy She drew furious censure from Gadess when she deduced Garudi was really Guardi Stol, Rom's brother. Knight of the Devil's Mountain, Mask Rock After Garudi found out the Hyribead wasn't in Emerald City he took direct action against the city, devastating it. Diondra was sent in to attack the survivors with aerial limpet mines and the Gyandlar Devils but when an earthquake struck the battlefield she fell into a chasm with Tough Trailer - and Rom's Wolf Sword, Ken Rō. As they had become entangled with a mine the pair had to work together to escape, with Tough Trailer even prioritising saving her over the sword. Rod Drill and Pro Truck Racer arrived to rescue them and she escaped the second the mine was removed - however, she ordered her minions to free the captive Leina as a gesture of thanks to the Machine Robo.Escape from the Underground - Pro Truck Racer Appears!
Diondra then discovered the Demon Sword of Medusa and tried to use it to turn one of the Machine Robo into a killing machine with the cursed weapon. While she had initially planned to trick Pro Truck Racer into taking the sword but it instead ended up with Tough Trailer; Baikanfu was able to destroy the weapon and release Tough Trailer from its' influence, however. Curse of the Demon Sword Medusa She was behind the experimentation that turned the Battle Rock Mars into a monster; when she found out her subject had developed feelings for Leina she kidnapped the latter, using her to keep Mars angry and dangerous but Baikanfu was able to stop him. Battle Rock Mars' Tears She continued her rivalry with Garudi; when he was trapped in a mysterious temple she tried to get Gadess to destroy the building. He saw through Diondra's jealousy and refused, though she attempted to bomb it herself - leading to Garudi swearing revenge against her. The Four Treasures of the Mysterious Ruins Her nose was put further out of joint when Grujios reappeared. Baikanfu Disappears in Space Wanting to find out information on the Hyribead, she chased down Cross Rock but soon after was caught by Amber Man, along with Blue Jet and Phantom Robo. Along with Garudi, she tried to persuade the Jewel Man that the Machine Robo were the aggressors in the conflict but once Amber Man told them what he knew of the Hyribead she attacked him and trying to steal the Phoenix Armor. She threatened to kill him if Rom didn't surrender but Machine Robo reinforcements drove her into another retreat. Save Amber Man, Blazer Cannon!
Gadess' growing fury at his underlings led to her to work together with Garudi and Grujios on their next scheme, which saw her lead a diversionary strike on Harley Robo's settlement, drawing Rom, Blue Jet, Rod Drill and Pro Truck Racer away from Emerald City. While Rom was able to figure it out, Grujios was at least able to steal the Phoenix Armor, pleasing Gadess. Close Call, Land Commander 5! She then excavated the Dragon Waterfall searching for the Lion Shield, believing she had inside help from Heli Transer. He was however playing her, trying to delay her until reinforcements arrived. His strategy worked but in the resulting fight she was able to get the Lion Shield to the Varigale-X and present it to Gadess. Raise Your Gun, Heli Transer! She then attacked the Battle Base when Rom took Pro Truck Racer and Bike Robo to find the Wheelmen but was unable to make any progress before their mission was complete. Full Power, Wheelmen! She later again tried to sacrifice Garudi to claim the Wolf Sword that formed part of the Hyribead, capturing it from Magna Rock; however, after she took it to Gadess, Grujios realised the sword was a fake. Secret Valley of the Fossil Men
Diondra then launched the powerful weather-controlling weapon Phenomena at the Battle Base, devastating Cronos. This forced the Machine Robo to lead an all-out attack on the Gyandlar mothership, which she defended along with the Devil Satan 6 - but only after Gadess had shown his dissatisfaction by slashing her face. Power Riser, Break Through the Enemy! The Machine Robo forced their way inside, with Diondra and Garudi heading to see Gadess in the throne room. However, he revealed himself to be an illusion - the real Gadess was elsewhere with all four elements of the Hyribead, and had no plans to share its' power. The betrayal greatly damaged Diondra's sanity. Baikanfu - Cry of Anger! She and Garudi were trapped in the throne room with the forward group of the Machine Robo army; as Garudi fought Baikanfu she broke out the revelation they were brothers. She had hoped it would give her comrade an opening in the fight but instead it began to awaken his memories of being Guardi Stol. Diondra tried to intervene but her whip was destroyed by Pro Truck Racer. Rom was able to free his brother from the Garudi armour but Gadess then began melting the throne room and everyone inside. Mighty Fortress, Heavenly Sword - Jet Don't Die!
While the injured Jet was able to free them all with his Blazer Cannon Diondra ignored Tough Trailer's pleas and opted to stay in the melting throne room, still begging Gadess for forgiveness. The Final Battle of Cronos
