The MSN-001X Gundam Delta Kai (aka δ Kai or δΧ) is a prototype transformable mobile suit developed from the MSN-001A1 Delta Plus as a technology demonstrator. It appears in the Mobile Suit Gundam Unicorn video game, Mobile Suit Gundam U.C. 0094: Across the Sky and UC-MSV.

Technology & Combat Characteristics

The final machine of Anaheim Electronics' Delta-type series, the Gundam Delta Kai is an enhanced version of the MSN-001A1 Delta Plus, which is used to demonstrate new experimental technologies that can be used for future mobile suits. As such, the unit is greatly overhauled from the regular Delta Plus, modifying both the MS and Waverider forms as well as enhancing its Variable Frame. Several Thrusters were also fitted into the unit's legs and back skirt which allows the MS to fly in both space and under gravity, giving it tremendous amount of speed and maneuverability. The overall Waverider mode can also function as a subflight system when needed.

Aside from the aesthetic change, the Delta Kai is fitted with various experimental weaponry derived from older mobile suits. This gives it a higher attack power and versatility than the Delta Plus, however despite the amount of weapons equipped it is very complicated to use in a tactical situation. The Delta Kai is also equipped with a specialized system called Newtype Injection Trace Reformed Oldtype Psycommu System or N.I.T.R.O System for short, allowing regular pilots to gain Newtype-like abilities


  • Vulcan Gun
The 60mm vulcan gun has been a standard armament of Federation suits since the One Year War. While not very powerful and typically unable to penetrate mobile suit armor, the vulcan gun is useful in intercepting missiles/rockets, destroying mobile suit sensors, and engaging lightly-armored targets such as tanks and small aircraft.
  • Long Mega Buster
A specialized Beam Rifle with a power output comparable to a beam cannon. The beam of this weapon could destroy a MS with a direct hit. It was originally developed for the MSN-001A1 Delta Plus from the FA-00100S Full Armor Hyaku Shiki Kai's Mega Buster.
  • Beam Saber
The Delta Gundam Kai's close combat armaments, they are stored in the rechargeable racks on the shield. The beam saber is capable of cutting through any metal that has not been treated with anti-beam coating. They are also dubbed as beam cannons while mounted in the shield and could be utilized in Waverider mode, a feature similar to the MSZ-006 Zeta Gundam's beam sabers/guns.
  • Proto Fin Funnel
The Delta Kai mounts two Proto Fin Funnels on its back. Using the NITRO System, they may be deployed efficiently even by non-Newtypes, giving the pilot all-direction attack ability. However, their large size would theoretically make them an easier target on the battlefield should they ever be utilized in combat.
  • Shield
A standard defensive feature of most mobile suits is an arm-mounted shield. Originally a thick piece of extra armor designed to stop physical rounds, shield technology has been forced to adapt to the development of beam weapons by incorporating an anti-beam coating. Gundam Delta Kai's shield also has the function of serving as the unit's forward section in Waverider mode. Beside the Beam Sabers/Beam Cannons, it can mounts a large variety of weapons.
  • Burst Bolt
Optional close-combat weapon that can be mounted on the front side of the shield. It produces a disruptive effect through a combination of explosive force and high voltage power using a built-in capacitor. A similar weapon is used by the FA-00100S Full Armor Hyaku Shiki Kai.
  • Mega Machine Cannon
Optional weapon that can be mounted on the front side of the shield. Developed by Strategic Naval Research Institute (SNRI), it fires heavy-caliber armor-piercing rounds. The Mega Machine Cannon could also be used by the D-50C Loto.
  • High Mega Cannon
An optional weapon that can be mounted on the front side of the shield, the High Mega Cannon can seriously damage a mobile suit with even a glancing hit, and in some case, total destruction. Developed with data obtained from the MSZ-010 ΖΖ Gundam, its output has been reduced to about 46% [1] in order to lessen the burden to the generator, resulting in an output of 23 MW.

Special Equipment & Features

  • "NITRO" Psycommu System
Gundam Delta Kai is equipped with the special Newtype Injection Trace Reformed Oldtype (NITRO) Psycommu System. The system projects large amounts of data into the pilot and allows for better response time with the unit and enhanced attack capabilities. With this system, an Oldtype pilot can acquire abilities suitable enough to manipulate the Fin Funnels mounted on the Delta Kai. It causes the Delta Kai to produce blue flames during full output. Because the system has been modified and optimized to "strengthen humans", the brain of the occupant is forcibly rewritten when the system is functioning. As a result, the personality of the pilot becomes more aggressive.


Anaheim Electronics specially converted one Delta Plus into the Delta Kai, used by the Federation for testing the NITRO System and its weapons. It is fielded in a mock combat against the MSN-001A1 Delta Plus and instantly defeated the Delta Plus in battle before it encountered the The Sleeves. Despite the numbers, the abilities of the NITRO System instantly took out all units, even though the system is proven to be dangerous to the pilot.

Soon after the battle, the unit was transferred to Earth and was heavily modified into the MSN-001X[G] Land Combat Type Gundam Delta Kai on which it performed several performance tests.

  • Delta is the 4th letter of the Greek alphabet. In the system of Greek numerals it has a value of 4.
  • Chi is the 22nd letter of the Greek alphabet. In the system of Greek numerals, it has a value of 600. Coincidentally, it is pronounced "Kai", the same as the Japanese word for "customized/modified".
  • This is the only MS in the Delta family that has a ground-use version.
  • The Kai appears to be the only MSN series suit that follows the traditional Gundam design, as opposed to the MSN-00100 Hyaku Shiki, the MSN-001A1 Delta Plus, the MSN-06S Sinanju and Sinanju Stein, and others.
