Standard Equipment:

Can summon/pilot:

- The original mobile suit used by the earth forces. It was relatively weak with a lighting staff as it's primary weapon. Due to its small size, it was easy prey for most of the aliens. The RX battle suits came in a variety of styles, often visually customized by squadron or individual pilot. The RX battle suits average between 9 and 10 meters tall and are the Earth forces’ main weapon against the bug-like aliens early on in the struggle.

  • Plasma Lancer
  • Plasma Bianchi
  • Californium Bomb
  • Beam Spray Gun
  • Plasma Lancer: The RX-7 Machine Weapons possess a double edged lance that they use in melee combat.
  • Plasma Bianchi: A short staff that becomes charged with electricity and strikes an enemy.
  • Plasma Sword: RX-7 electric shock weapon. This is a thing that can strike an enemy by stabbing an enemy. It can also be used as a sword.
  • Triangle Claw: The machine is also equipped with 2 razor sharp progressive knives which were sheathed within the left and right forearms.
  • Californium Bomb: The RX-7 could be outfitted with a nuclear weapon used primarily to take out larger insect carrier craft. Because life as a nuclear warhead is as short as 3 hours, it is always required to be used in battle.
  • Beam Spray Gun: This appears to be a handheld weapon for the RX battle suits that never made it past the planning stages, made to fire explosives.
  • Degeneracy Generator: Utilizes an ultra-compact version of the ones used in ships and buster machines.
  • Inertial Canceler: A device to mitigate inertia.
Optional Equipment:

Moby Dick #1 and #2

  • Moby Dick #2: Exterior engine from a Spiegel training vessel the RX suit can strap to that could reach near the speed of light in a minute from the travellers point of view (equating to 3 months from the observers point of view due to time dilation).

- One of the core units constituting the lower body of the Gunbuster, which transforms and combines with Buster Machine #1. It has a high electronic warfare ability, with excellent reconnaissance ability.

  • Degeneracy Generator: The standard power source for Buster Machines and other mecha based around the principle of black holes, that generates a limitless power supply.
  • Circumference Gun Cannon: Laser projector mounted at the top of minus millions of degrees.
  • Buster Missile: Outfitted with missile launchers that can fire photon torpedoes.
  • Warp Engine: Engines that can propel the ship past the speed of light.
  • Inertial Canceler: A device to mitigate inertia.


Black Hole Bomb

- Created by mankind for the purpose of destroying the space monster nest located at the center of the Milky Way Galaxy. Desgined as a black hole bomb, the machine's oval body housed Jupiter, compressed to 1/30,000th its original size, while also acting as a fuse to detonate the 3,000 slave units spread across a radius of 10,000 light-years surrounding the galactic core. It also features a console panel to be piloted from within.

  • Slave Generators: 3000 slave units deployed in the range of 10,000 light-year radius from the main body, when they detonate at the same time, a huge black hole is generated, swallowing the galactic center.
  • Barrier: Force field of 10^58 GeV.
  • Inertial Canceler: A device to mitigate inertia.

Intelligence: Gifted overall

Weaknesses: Unknown | Fodder mecha | Unknown | Cannot be used by any other means other than a bomb



Notable Attacks/Techniques:

  • Sekiun Defense: An omni-directional defensive stance assumed to have no openings.
  • Inazuma Kick: Kazumi performs a powerful kick with the RX-7 boosts up into the air while lighting flashes and comes crashing down upon the enemy with an electrified drop kick.

Inazuma Hanten Kick

    • Inazuma Hanten Kick: Like Inazuma Kick, but the RX-7 uses the force of its impact to rebound off of the enemy and land with another kick to the same location!'s basically a reference to one of Kamen Rider V3's attacks, the V3 Hanten Kick.
  • Inertial Balancer: An auto balance mechanism that keeps the RX-7 machine weapons stabilize.
  • Triangle Punch: The RX-7 Machine Weapon's razor sharp progressive knives which were sheathed within the left and right forearms extends to stab an opponent via a punch.
    • Triangle Cannon Punch
    • Triangle Act Punch
    • Triangle High Punch
  • Californium Hakudantou: Kazumi fires the nuclear missile from the RX-7 Machine Weapon.

  • Laser Cannon
  • Transform + Combine
  • Laser Cannon: Fires its frozen cannon of minus millions of degrees.
  • Combine: Combines Buster Machine #2 with Buster Machine #1 and become Gunbuster.


Super Inazuma Kick

  • Super Inazuma Kick: Kazumi with Noriko in Gunbuster launches up, descends with one leg extended and the other bent, and drop kicks the opposition.

Key: Kazumi | RX-7 Giselle | Buster Machine #2 | Buster Machine #3


Degeneracy Generator 「縮退炉しゅくたいろ」: A result of Tannhauser's research, the Degeneracy Generator is an effectively limitless power supply and the key to FTL. Two artificial Micro Black Holes are spun in tandem with overlapping fields so as to create a naked singularity within which "subspace" can exist. The singularity is referred to as the Tannhauser Gate, due to the visual effect of objects entering it seeming to pass through a portal with a trailing rainbow of light. The standard power source for Buster Machines and other mecha up until the technology was lost sometime between Top o Nerae! Gunbuster and Top o Nerae 2!: Diebuster. The Degeneracy Generator plays an important role in both series.



- Kazumi is named after the wife of Toshio Okada, co-founder and first president of Gainax.

- She is a scorpio.

- Her blood type is B.
