XXXG-00W0L Gundam Lucifer

XXXG-00W0L Gundam Lucifer is two Gundams based on Wing Zero, but appearing solely in the semi-canon story Tiel's Impulse (Template:Lang), published in the Ultimate Playing Book (Template:Lang), a model kit magazine-book.

At a point prior to the end of Gundam Wing, the Romefeller Foundation used the data from the Gundams and used it to develop new mass-produced mobile suits. Lucifer was a test unit based on Wing Zero, and was used to trial an improved ZERO system, Zero 2.0. Although more powerful than the original system, ZERO 2.0 forced the pilot to take certain actions, as opposed to the original ZERO 'suggesting and urging' them.

Following these tests, Seraphim was designed. Its ZERO 2.5 reduced the side effects seen in ZERO 2.0, and the wing binders were moved from the back to the skirt of the mobile suit. Six Seraphims are seen as completed in Tiel's Impulse. Similar to its predecessor, the ZERO 2.5 was known to take control of the mobile suit
