A Hyper-Deuterion Engine (ハイパーデュートリオンエンジン Haipādeyūtorion Enjin?) is a revolutionary mobile suit reactor used within the Cosmic Era timeline.


Created by ZAFT and also used by Terminal, this new type of mobile suit reactor is a hybrid of the nuclear reactor with the Deuterion Beam Energy Transfer System.[1][2][3][4] With the two systems complementing each other, it is possible to obtain more power than the previous nuclear-powered machines, and theoretically, unlimited self-sustaining power would be produced.[3][4]

Mobile suits using the Hyper-Deuterion Engine are considered to be nuclear powered,[5] and is naturally equipped with a Neutron Jammer Canceller to allow the nuclear reactor to operate. The engine uses an ultra-compact nuclear reactor, which is smaller and more powerful than conventional nuclear reactor, and is equipped with a battery as well. There is also a claim that mobile suits adopting this system continued to have the Deuterion Beam Energy Transfer System's deuterion beam receiver installed in the forehead.

How the Hyper-Deuterion Engine works is unclear. Although it was said that a mobile suit with this reactor would not suffer a power down during combat, it is possible to drain the power reserves to a near-critical level of 17% as proven during the Destiny Gundam's first engagement with the Strike Freedom.[3] How this is possible is still unknown, though it is speculated that due to Destiny's prototype nature, its engine may have malfunctioned after being pushed to the limit too quickly, resulting in it not being able to recharge in time.[3] It has also been suggested that the Deuterion Beam Energy Transfer System could not keep up with the energy consumption.[4]


This new type of mobile suit reactor was created by ZAFT during the Second Alliance-PLANT War and tested on the prototype ZGMF-X3000Q Providence ZAKU. Afterwards, the reactor was installed on ZAFT's newest Gundam-type mobile suits, the ZGMF-X42S Destiny Gundam and ZGMF-X666S Legend Gundam. Terminal, after acquiring the data for this technology, equipped it on the ZGMF-X19A Infinite Justice Gundam and ZGMF-X20A Strike Freedom Gundam.


  • In the Super Robot Wars series, the Hyper-Deuterion Engine provides 25% energy refill (of the unit's maxiumum energy) per turn. Thus the units that have this feature will only very rarely run out of energy, especially if their energy capacity has been upgraded. Even if there are circumstances in which they actually ran out of energy, they will get a nice amount of energy on the next turn.
    • In Super Robot Wars UX the ability was nerfed to only 10% for unknown reasons, while the 25% energy regen was given to the Twin Drive System.
  • The Hyper-Deuterion Engine was omitted in Super Robot Wars Z2. The Mobile Suits that are supposed to have this feature in the actual story simply only gain a small energy regen (or medium, after fully upgraded) as their passive ability. This is similar to the incident where the N-Jammer Canceller was completely omitted in Super Robot Wars J without a replacement ability. This might have been done for simplicity as the game is known for having a particularly large amount of units with diverse abilities.
  • In Dynasty Warriors Gundam Reborn, the Deuterion Engine is a Burst Type function that grants mobile suits an HP regen when in effect.
  • In the SD Gundam G Generation series, the Deuterion Engine is a combination of Deuterion Beam Energy Transfer System and Neutron Jammer Canceller, where mobile suits can remotely recharge energy from warships and negate the cost of using defensive abilities.
  • A thing to note is Deuterium has been used as fuel for modern nuclear reactors (in the form of heavy water) and the nucleus of Deuterium is called Deuteron, which is obvious where Hyper Deuterion Engine takes inspiration from.
