BirthOfASpartan - Augmentation

A screen monitoring Carter-A259's augmentations.

Project: CHRYSANTHEMUM is a set of SPARTAN-III bio-augmentation procedures, similar to those of the SPARTAN-IIs.[1][note 1] With advances in technology, however, the casualty rate for SPARTAN-III candidates was 0%, as opposed to the 56% casualty rate of the SPARTAN-IIs.[1]


Drug Description Effect
8942-LQ99 "carbide ceramic ossification catalyst" drug.[1] Skeletons become virtually unbreakable, allowing survival in harder impacts.
88005-MX77 "fibroid muscular protein complex" drug.[1] Increased density of individual's muscles, allowing heavier lifting.
88947-OP24 "retina-inversion stabilizer" drug.[1] Color sharpness is significantly improved upon, and night vision is adapted.
87556-UD61 improve the colloidal neural disunification solution[1] Greatly improves the individual's reaction time, decreasing the time taken to react by 300%. "Spartan time".

Gamma company also received the following in addition to the above.

Drug Description Effect
009127-PX (cyclodexione-4) bipolar integration drug Counters the effects of 009762-OO.[1][2][note 2]
009762-OO Neural-altering non-carcinogenic mutagen. Alters key regions in the individual's frontal lobe.[1][2][note 2] Enhances aggressive response to dangerous levels. Requires regular doses of 009127-PX and 009927-DG to be taken to avoid uncontrollable aggression.[2]
009927-DG miso-olanzapine Counters the psychological effects of 009762-OO.[1][2][note 2]


During the battle of Pegasi Delta, Tom-B292, 12 years old at the time and equipped only with SPI Armor, engaged a Covenant Elite armed with a Plasma Pistol and an Energy sword in hand-to-hand combat. The Spartan's enhanced reflexes allowed him to dodge a Plasma Pistol bolt and sword swing at point blank range. He then proceeded to throw the Elite to the ground and finish it off with his Assault Rifle. It is also stated that during the battle, Elites and Jackals moved out of cover because they realized that it was suicide to face Spartans in close quarters.[3]

Spartan-IIIs were also described to have been moving with "speed and reflexes that no Covenant could follow". "They dodged, snapped necks and limbs, and with captured energy swords, they cut through the enemy until the field ran with rivers of gore and blue blood". The 300 or so Spartan-IIIs faced thousands upon thousands of Covenant, including Covenant air support, and were described to have been winning the battle until 7 Covenant Cruisers emerged as reinforcements.[3]

It was stated by Mendez that as Spartans grew older, they only grew stronger and faster as their bodies grew accustomed to their augmentations.[4] During the battle on Pegasi Delta, the Spartan III's of Beta Company were roughly 12 years old. If the Spartan-IIIs lived long enough to mature, their physical abilities would have improved significantly.

During The Fall of Reach, SPARTAN-B312 was capable of knocking out a Sangheili General with a single elbow strike before shooting it twice in the head as it was struggling to get up. While continuing to make his last stand, he was also capable of dealing single strikes to multiple Zealots and Ultras, that caused them to forcefully stagger back, before finally being subdued.[5]

Spartan III's from Gamma Company were given a special mutagen called "009762-OO", this augments key regions of the subjects brain, allowing them to endure physical trauma's that no normal human or Spartan II could withstand. For example, Dante-G188 thought he had been "nicked" even though he actually had needler shards tear open his entire chest.[6] It also allows them to access reserves of strength and endurance no normal human could call upon.[7] Although these augmentations offer extraordinary benefits in combat, they are not without faults, the mutagen needs to be countered with regular doses of cyclodexione-4 and miso-olanzapine or else the Spartan will loose their strategic judgment over time and be more susceptible to instinct driven behavior in combat.[6]


  • Chrysanthemum is the Latin name for a plant species.


  1. Even though most Spartan III's seem to have one less augmentation than the Spartan II's, it can be inferred that the catalytic thyroid implant that the Spartan II's received was rendered redundant since the Spartan III's received human growth hormone months prior to their augmentations. Which in turn, allows the Spartan III's to not require the former augmentation.
  2. 2.0 2.1 2.2 These drugs were illegally authorized and injected into the SPARTAN-III Gamma Company by Kurt-051. It was outlawed by the UNSC Medical Corps in 2513.
