Haptism, Allelujah

アレルヤ・ハプティズム

GN-007 Arios Gundam (S2)
GN-011 Gundam Harute (Movie)
Most of Allelujah's childhood remains unknown. He somehow became an orphan and was subjected to experiments within the Human Reform League program. This experimentation caused a split in Allelujah’s personalities, revealing a darker side to the usually gentle man.
A series of events left him and others adrift in space, and for survival, the darker half took over and killed everyone on board. It is possible that this is when Allelujah was discovered by Celestial Being.
Like all other Gundam Meisters, he was selected by Veda to serve as a Meister, a position he maintains.
Allelujah's personality is divided into two halves due to brain enhancement. The two halves are distinguished by the darker half being called 'Hallelujah,' as well as Allelujah's hair covering the left side of his face to reveal a gold-colored right eye.
The dominant personality is Allelujah, a decidedly kind and gentle person. When the rest of the Ptolemaios crew went to Earth, he chose to stay and assist with maintenance. He dislikes killing, which often leads to confrontation with his other half, such as when he was about to fire upon the HRL’s Super Soldier Facility.
Hallelujah, on the other hand, holds a strong survivalist view: kill or be killed. He will do anything to survive. When Allelujah is conflicted about what to do, Hallelujah offers to 'take over' Allelujah's body so he will not be so morally conflicted. Hallelujah has gone so far as to claim he is the embodiment of Allelujah's desires, taking action when Allelujah's morals get in the way.
