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.

Technical Information

This new reactor is a hybrid system created by ZAFT (and also used by Terminal) which combines a nuclear reactor with deuterion conversion technology. These two technologies complement each other and thus, in theory, provide an endless supply of power. The process works as follows: the deuterion converter functions like a battery, storing excess power coming from the nuclear engine as deuterion pairs, which are then funneled back into the reactor to continue the nuclear reaction. Thanks to this, hyper-deuterion engines are far more efficient than conventional nuclear fission reactors.

Despite using the same reactor, the "G.U.N.D.A.M" acronym for ZAFT's mobile suits is Gunnery United Nuclear-Deuterion Advanced Maneuver, while the acronym for Terminal’s mobile suits is Generation Unsubdued Nuclear Drive Assault Module. It has been suggested that the reason for this difference between the Destiny/Legend and Strike Freedom/Infinite Justice OS is because the former draw their power from the deuterion battery, while the latter draw it directly from the reactor, leaving the deuterion battery as a backup power supply, to be used in case the Neutron Jammer Canceller needs to be deactivated. Another possibility is that the Destiny/Legend use a new operating system developed by ZAFT specifically for those mobile suits, whereas the Strike Freedom/Infinite Justice use a modified version of the OS originally equipped by the Freedom and Justice. However, this matter still awaits official confirmation.


This new type of reactor was created by ZAFT during the Second EA-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 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 supposed to have this feature in the actual story simply only gain 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.
