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 Kyrios during 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. The difference between the two personalities often forms a conflict between them, as they rarely work together in different situations. In Season 1, despite being a Gundam Meister for Celestial Being, Allelujah often hesitates during his missions, because he is afraid that the people (enemies or civilians alike) might get killed for no good reason. This causes Hallelujah to get angry at him at times, criticizing that Allelujah often tries to impose his opinion on others, without even understanding them, and worries just so that he could feel better about himself. He added that this hesitation of Allelujah, especially in the battlefield, will be the reason that they will get killed by the enemy in the future. On the other hand, Allelujah in some ways despises Hallelujah, as Hallelujah can easily kill people without remorse. Despite this conflict, there are times when the two can still settle their differences and fight together when needed (i.e. when their preferred goals coincide), just like during the Battle of Lagrange 1 against the UN Forces, the Battle in Lagrange 2 against the Innovators, and the Battle of Earth against the Extraterrestrial Living-metal Shape-shifter (ELS). In Season 2, Allelujah finds his reason for fighting because of Marie Parfacy. However, he tries to force his belief on her of making her not fight, even though she is capable of helping the Ptolemy during battles. A conflict eventually arises between them when Marie, now as Soma Peries, decided to fight again after her surrogate father, Sergei Smirnov, was killed in combat against A-Laws. Alellujah tries to stop her, but Soma ignores him, thus forming a rip in their relationship. However, after the Innovator's infiltration in the Ptolemy, Allelujah finally tries to understand Soma's reason for fighting and respect her decision. The two eventually understand each other and decide to fight together during the Battle in Lagrange 2. Allelujah left the Ptolemy after the battle against the Innovators. He and Marie set out on a journey to finally find their own reason for living, aside from fighting in the battlefield. However, after being attacked by the ELS, Allelujah and Marie decide to return to Celestial Being to fight the invasion of the ELS. Allelujah became more understanding of others and was more than willing to unite with Hallelujah one final time to defend Earth.
