Allelujah Haptism is a Gundam Meister and one of the protagonists in Mobile Suit Gundam 00. Allelujah was an escaped failed-experimental super-soldier of HRL's Super Human Research Institute, who made his way into Celestial Being. He piloted the GN-003 Gundam Kyriosduring Season 1; the GN-007 Arios Gundam and its upgraded GN-007GNHW/M Arios Gundam GNHW/M in Season 2. He pilots the GN-011 Gundam Harute with Soma Peries in Mobile Suit Gundam 00 The Movie: A Wakening of the Trailblazer.
Allelujah is overall a quiet, brooding, and gentle person. Even though he rarely opens up to people, he shows concern and worries about the situations of those close to him, especially the Ptolemy Crew. He also feels bitterness whenever someone dies, even if it's a death of an enemy. Even in the battlefield, he is not a type of person that could hide his guilt of killing someone by saying that he is just doing his job. He hates war, but because of his fate as a Super Soldier, he thinks that he will always be in the battlefield because of his upbringing.Because of that, he chose to accept being one of Celestial Being's Gundam Meisters. He believes that in the organization, it is possible to end conflicts and evils around the world; and he's glad that he could contribute to that by using himself and his own abilities on the battlefield.
Allelujah has another personality, named Hallelujah. Hallelujah was formed after Allelujah received his quantum brainwave surgery in the HRL Super Human Research Institute. Hallelujah is also the one who had killed Allelujah's friends while escaping the institute. To distinguish from Allelujah in Season 1, Hallelujah reveals his golden right eye when he is in charge. In contrast to Allelujah, Hallelujah shows no concern about other people other than himself. Even at the cost of everything, he'll do anything to survive. Whenever he feels that Allelujah is doubting during battle, he'll immediately switch in and do what he deems is necessary, just so they would not get killed. He also finds amusement in seeing other people die and suffer.
Skills and abilities
Allelujah is a genetically modified human, called a Super Soldier, developed by the HRL's Super Human Research Institute.Allelujah was surgically implanted with quantum brainwaves for super reflexes and has a modified body to maintain his peak physical condition; Allelujah's mind and body were configured specifically for combat purposes. However, even with such abilities, the scientists in the institute deemed him a failure for having a murderous split personality. Unknown to them, the two personalities can work together and bring about the true potential of the Super Soldier they desired.
The two personalities have their own range of specialty when it comes to combat situations. Allelujah is the rational one, being the one to think about tactics during combat. Hallelujah, on the other hand, is the one responsible for their reflexes and their battle intuition. When uniting both their strengths, they act as dual processing brains with a reflexive body, giving them a superb advantage in the battlefield.
- Hallelujah, Halleluyah and the Latin form Alleluia are transliterations of the Hebrew word Halleluya, meaning "Praise God".
- Hallelujah is referenced twice in the very first episode, despite not appearing until episode 5. First is when Kyrios is being sortied, he says "A real battle, Hallelujah, just like you wanted" and second is when he says "Hallelujah, the worlds begun to change."
- Allelujah shares similarities with Shani Andras, an Extended pilot in Gundam SEED, as both are modified humans for battle use, with two different colored eyes, and hair concealing one eye (though Allelujah has both of his eyes visible in Season 2). Another connection between the two pilots is that they both have Richard Ian Cox as their English voice actor.
- Also of note is the similarity of the super-soldiers Allelujah/Hallelujah and Soma/Marie to the cyber-newtypes of the original U.C. series of Gundam, due to their artificial (and flawed) creation for the purpose of space warfare. This shows itself right down to the classic "newtype flash" passing across their eyes when they sense each other, as well as being followed by the same kind of crippling headache that cyber-newtypes experienced and sometimes caused in natural newtypes.
