The group was formed after the defeat of Kaiser Belial to deal with the remaining Legionoids. Afterwards, it functions primarily like the Space Garrison in Zero's home universe. Later the group gained another member "Jean-Nine", the robot that was based on Jean-Bot and was originally named "Jean-Killer" and created by Beatstar. The name Jean-Nine was given by Princess Emerana. They reappear in Ultra Zero Fight as a cameo at the end and take part in the story of Season 2 to fight the Darkness Five.
All members of the Ultimate Force Zero is set to return in this upcoming movie.
- The name "Ultimate Force Zero" was created by Zero.
- Each member of this group are homages/updates to other works of Tsuburaya Productions, Ultraman Zero is based on Ultraseven, Glen Fire is based on Fireman, Mirror Knight is based on Mirrorman and Jean-Bot is based on Jumborg Ace as Jean-Nine is based on Jumborg 9.
- Jean-Nine's name is given because he is the 9th hero that fight alongside Ultraman Zero as Emerana counts Zero, Glen Fire, Mirror Knight, Jean-Bot, Rei, Hyuga, Gomora, Litra and Jean-Nine. The name also was given by Emerana. (Note: Before Emerana named him Jean-Nine, Glen Fire suggested name "Jean-Bot II Dash" which references Jumborg 9's transforming phrase "Jum-Fight 2 Dash!")
- The voice actors of all of Ultimate Force Zero's members coincidentally voiced Mobile Weapon Pilots from the Gundam franchise. As shown:
- Ultraman Zero/Mamoru Miyano: Shams Couza (Gundam SEED), Setsuna F. Seiei (Gundam 00).
- Glen Fire/Tomokazu Seki: Domon Kasshu (G Gundam), Yzak Joule (Gundam SEED) Tomache Massarik, Chris Royd (Victory Gundam), Meiser (Gundam Wing).
- Jean-Bot/Hiroshi Kamiya: Tieria Erde (Gundam 00), Zeheart Galette (Gundam Age), Shams Couza (similar to Mamoru) (Gundam SEED)
- Mirror Knight/Hikaru Midorikawa: Lee Ron (Mobile Suit Victory Gundam), Heero Yuy (Mobile Suit Gundam Wing),
- Jean-Nine/Miyu Irino: Saji Crossroad (Gundam 00)
- The reason for the non-Ultra members of the team do not have visible mouths was because the designers wanted to emphasize the fact that they were not based on human/humanoid life forms.
