After Beatstar captured Jean-bot and Emerana in a giant sphere, Beatstar created the ultimate robot based on Jean-bot, Jean-killer. The rest of the team tried to help them before they were dragged in, but it was too late as the gate closed and it disappeared. The giant sphere appears in another dimension right when Hyuga and Rei were going to meet up with their ZAP SPACY team at Planet Buram for a vacation. As the giant sphere was heading to Planet Buram Hyuga contacts Kumano to evacuate the population off the planet as fast as possible. Rei found entry through the damaged gate, in there they found Emerana and are attacked by Legioniod Beta, after Gomora defeated it Ace Killer, King Joe and Imperializer appeared and defeated Gomora. With arrival of Ultimate Force Zero as they defeated them, Beatstar sent Jean-killer to fight Ultimate Force Zero and they were easily defeated, brainwashed and with red eyes Jean-bot arrived and attacks Emerana, Rei and Hyuga, Rei tried to hold him off with Litra as Gomora hasn't healed from the damage, with Litra defeated and Jean-bot was going to kill Litra, Emerana stands before Jean-bot then orders him to stop as Jean-bot held his attack and Jean-killer also heard her voice and stopped attacking Ultimate Force Zero then paid attention at Emerana and his eye began to turn from red to yellow but it stop turning at all as moment that Glenfire attacks him again. After Zero takes him far away and followed by Glenfire and Mirror Knight, Jean-bot began to regain his consciousness but he had to shut down his system to resist Beatstar's control. Jean-bot told Emerana, Rei and Hyuga about everything he knows about Beatstar and Jean-killer, Hyuga told Emerana that when she ordered Jean-bot to stop, Jean-killer also noticed and stop as well. Emerana begins to think that Jean-killer also has a heart like Jean-bot as he was based on him and makes Jean-killer Jean-bot's younger brother then they started to repair Jean-bot with help of Kumano's knowledge. As the fighting with Zero continues, before Zero had a chance to defeat Jean-killer, Jean-bot stops Zero in time and tells everyone that he is his brother, the rest of the team is surprised when Jean-bot try to persuade Jean-killer that living-life forms is the not enemy, as he still under the control of Beatstar he continued to attack Jean-bot and the team. Emerana arrives and persuades him to open his heart to the truth to make up his own mind, he responds but Beatstar forcefully gains control of him again and he attacks Emerena with beams from his eyes and holds back the team with electric blasts to make them stay where they are, even how much Rei tried to stop her, Hyuga told Rei that they should trust her. She still tries to convince Jean-killer as she believes that Jean-killer has a heart as his attack is missed in countless times to Emerana, He stopped after he saw Emerana's tear, the team is freed and everyone is surprised when they see Jean-killer's tears. Everyone taught him about life, heart and the truth about organic lifeforms not being his enemy. Jean-killer had make up his own mind but Hyuga reminds everyone that is time growing short before sphere will hit the planet, The Team and Jean-killer destroyed all surrounding Legioniods. Ultraman, Ultraseven and Zoffy arrive to buy them time before the sphere hits the planet. Jean-bot begged Jean-killer to reveal Beatstar's Location Jean-killer told them he's at a half cut moon. The team jump up to the moon and found a several of King Joes and Imperisers. Jean-bot, Glenfire, Mirror Knight and Rei summoned Gomora to hold them for Zero, so Zero will be able to stop Beatstar. As Beatstar won't allow the sphere to stop without a fight, Zero was over powered, Beatstar told Zero to give up but Zero won't give up and tells Beatstar that Living-life forms could learn from their own failure to stand up again even robot like Jean-killer as well, at that moment Zero is Pushing back Beatstar with Jean-killer's help Zero is able to stand and fight. Jean-killer tried to persuade Beatstar to reconsider that the Living-Life form is not enemy but Beatstar refused. Jean-killer fought against Beatstar with Hyuga as the motion control pilot, Beatstar is defeated by his off calculation that he only used all Jean-killer fighting style data to against him, Zero combined his Twin Eye sluggers and destroys Beatstar. Before his death Beatstar admitted that he just fear that living-life form will turn evil like his creator. After Everything is over Jean-killer had been renamed by Emerana as "Jean-nine" and Zero had him joined The Team as well. Emerana told Jean-bot to be a good big brother to him. After Ultraman, Ultraseven and Zoffy left to Land of Light, Ultimate Force Zero is ready to save Universe again.

 * Jean-nine is the only robot to show visible emotion. He experienced it when he first appeared in the series.
 * Jean-nine's first name, Jean-Killer, is based on the name JumKiller, One of Jumborg Ace's villains.
 * The main reason why Jean-killer's eyes are red is because he was under the command of Beatstar or Tomoya Ichijouji and under the influence of his masters' evil deeds. As Jean-Nine they turned yellow when Beatstar was destroyed by Zero and Tomoya lost against Ginga.
 * Tomoya's recovery of the Gun-Pad and Ginga's own words implied that Jean-Nine and perhaps all the Spark Dolls are still conscious on some level.
