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. Mobile suit using the Hyper-Deuterion Engine is considered to be nuclear powered. 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. How the reactor works and why the ZAFT's and Terminal's OS have different name is unclear. One weakness of the Hyper-Deuterion Engine is that mobile suit equipped with it could still drain its power reserve to a critical level, as shown during Destiny Gundam's first engagement with the Strike Freedom Gundam. How this is possible is still unexplained.
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 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.
