Ultraman Zero Gaiden: Killer the Beatstar


―Jean-Bot before deactivating himself

"He used me as the base for Jean-Killer. I believed he also copied my Advanced Artificial Intelligence."

―Jean-Bot said when he was captured

A year after Ultimate Force Zero's last battle with Kaiser Belial, Jean-Bot and Princess Emerana was kidnapped by Beatstar in his travel sphere. The remaining three Ultimate Force Zero, Ultraman Zero, Mirror Knight and Glen Fire broke into the sphere and tried to save them. Jean-Bot was later kidnapped, reprogrammed and become the main base model for Jean-Killer. While Jean-Killer attacked Ultimate Force Zero, Jean-Bot was ordered to eliminate Rei and Hyuga.

Zero took Jean-Bot away, and he began to regain his consciousness but he had to shut down his system to resist Beatstar's control. As the fighting with Zero continues, before Zero had a chance to defeat Jean-Killer, Jean-Bot stopped 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 Emerana 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 missed countless times at 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 had taught him about life, heart and the truth about organic lifeforms not being his enemy. Jean-Killer had made up his own mind but Hyuga reminds everyone that time is growing short before the sphere will hit the planet.

The team and Jean-Killer destroyed all surrounding Legionoids. 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 that he's on a half-cut moon. The team jump up to the moon and found a several of King Joes and Inpelaizers. Jean-Bot, Glen Fire, Mirror Knight and Rei summoned Gomora to hold them for Zero, so Zero will be able to stop Beatstar. 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.

Ultra Zero Fight

Ultraman Geed The Movie: Connect The Wishes!



  • Jean-Bot is based on Tsuburaya Productions earlier creation, Jumborg Ace.
  • The name of Jean-Bot's ship/plane is named Star Corvette Jean Bird.
  • Jean-Bot is always referred by Glen Fire as Grilled Chicken (焼き鳥 Yakitori).
  • Jean-Bot appears in Ultraman: Another Genesis as a human transformed into a robot.
  • Jean-Bot's trait is similar to that of Tieria Erde, one of the characters of Mobile Suit Gundam 00 (even to the point of sharing the same voice actor, Hiroshi Kamiya), as shown:
    • Both are artificial intelligences which inhabits a machine (Tieria was an Innovade, a human-like being until he died and had his mind saved into computer data).
    • Both are protective towards their superiors, Emerana and Veda.
    • Both appeared to be genderless among their group members (Jean-Bot is at the least possess masculine programming).
    • Both initially saw the main character (both voiced by Mamoru Miyano), Ultraman Zero (in Run's body) and Setsuna F. Seiei potentially as a threat to their superiors until they gain their trusts.
    • If discounting Jean-Nine, Jean-Bot and Tieria Erde are the only odd one out in their respective groups: Jean-Bot is the only robot and Tieria is the only non-genuine born human, being an Innovade.
    • Both had "siblings" that are similarly modeled after them, Jean-Nine and Regene Regetta, with said siblings initially played as their enemies to serve their masters (Beatstar and Ribbons Almark) but defected and helped the protagonists.
    • In Ultraman Zero Gaiden: Killer the Beatstar, Jean-Bot uttered one of Tieria's well-known quote: "You deserve ten thousand years of death!".
    • Another interesting fact is that Tsuburaya Prod. is aware of this, and additionally Jean-Bot's concept was also taken from Captain Gundam from SD Gundam Force, whom also voiced by none other than Hiroshi Kamiya himself.
  • For once, Ultraman Nice had pointed the similarity to Jean-Bot and Gridman. Ironically, Gridman's voice actor, Hikaru Midorikawa would voice Mirror Knight.
