Borr, a member of the Neon Genesis Junior High Students, presents as a short humanoid with vibrant orange hair styled in two low ponytails, contributing to an androgynous visual ambiguity. He routinely acts as a bodyguard for Sho Utsumi during daily activities.
During critical situations, Borr shifts into his Assist Weapon form, Buster Borr—a yellow-and-white twin-drill tank outfitted with missile launchers. This configuration integrates into larger combined forms, such as Powered Zenon's thighs or Buster Gridman's artillery platform. His combat arsenal includes standard missiles, Forest Extinguisher Missiles for fire suppression, and Sydney Super Adhesive Missiles that deploy hardening pink adhesive to ensnare targets.
In human form, Borr wields superhuman physical capabilities and combat proficiency, employing a jagged survival knife dubbed the Scrap Maker Dagger. His demeanor is snarky and brash, frequently expressing irritation at Utsumi's penchant for citing Ultra Series mid-battle. Despite being the youngest in his group, Borr exhibits acute observational skills, detecting suspicious behaviors others might overlook.
Design elements include a gold spinosauroid-shaped pin on his jacket, referencing *Superhuman Samurai Syber-Squad*. His Assist Weapon form directly mirrors the Twin Driller from *Gridman the Hyper Agent*, while his name "Borr" stems from the Swedish word for "drill," aligning with its U.S. adaptation localization. Attacks like the Sydney Super Adhesive Missiles pay tribute to Sydney Forrester, a character and pilot from that series.
