Borr (ボラー Borā) is one of the four Neon Genesis Junior High Students that act as support units for Gridman. He transforms into the Assist Weapon Buster Borr (バスターボラー Basutā Borā).


Borr displayed a sassy and outspoken personality. Arguably the youngest out of four, Borr is shown at times to be snarky and a showoff, confident with his abilities and easily annoyed by Utsumi and (to a lesser extent) Calibur's antics.



Borr showed up with the remaining two Junior High students after Anti had defeated Gridman and Calibur. The trio invited themselves into the Junk shop, already aware Gridman was alive. Borr used Rikka's phone to tell Calibur to come out of Junk. Defeat He and the other Assist Weapons continue to fight alongside Gridman and Yuta. Borr entered the battle for the first time when Gridman had to face off against Go'yavec, and combined with him to form Buster Gridman. Provocation

To awaken Gridman's true form, the Neon Genesis Junior High Students gained Acceptors and were integrated back into Gridman for the final battle. After that was over, he departed with Gridman back to the Hyper World. Awakening (Finale)

  • His counterpart in Denkou Choujin Gridman is Twin Driller, the second of the God Zenon set of Assist Weapons created and controlled by Ippei Baba and Yuka Inoue to assist Gridman.
    • His name is based off of Borr, the English name for the Twin Driller in Superhuman Samurai Syber-Squad.
    • The names of the missiles he fires are a reference to Syndey Forrester, the default pilot of Borr in Superhuman Samurai Syber-Squad.
  • Widely presumed to be female, Borr's voice actress Aoi Yuki confirmed on Twitter that Borr is in fact male.[3] Even Aoi Yuki acknowledges this surprising twist and calls him "Borr-chan-kun" (ボラーちゃんくん Borā-chan-kun).
    • There was some further confusion regarding Borr's gender because his Funimation voice actor Apphia Yu initially referred to him as a girl.[4] This has since been rectified.[5]
  • The brooch on his vest is a reference to the Dinobot, Scorn, from Transformers Age of Extinction.
  • When combined with Gridman, Borr's components took a similar appearance to Drill Max from Brave Fighter Exkizer.
  • Borr is very proud of his tank form's twin drills despite the fact, as Vit stated, they are mostly just for show.
    • Borr's drills are similar in appearance to the drill arms of the Godzilla Kaiju/Robot Heisei Moguera from Godzilla VS Spacegodzilla.
  • A recurring gag with Borr is that he kicks the shins of whoever annoys him. Sho is frequently on the receiving end of this.
