One of the two playable protagonists. He is part of the Keepers of Order, who watch over law and order in Al-Warth, and is also known as the 'Iolite Sorcerer.' He is strong-willed, cool-headed, and wishes to pursue the path of justice.
In order to discover the truth behind his life, along with what he can accomplish with the Dogmas that he has obtained since he was a child, he sets out on a journey.
- Alliterative Name: Iori Iolite. His real name, however, averts this.
- Bishounen: His face pretty much says it all with his good looks.
- Fake Memories: His real name is Iori Aoi, an Ordinary High-School Student in his 3rd year which comes from a world without Humongous Mecha with his parents and older sister. One day, he and his classmate Amari were brought over to Al-Warth and inducted into the Keepers of Order, complete with false memories of training there for several years.
- Hotblooded: Of the Kuudere Type-1 variant. Iori mentioned he doesnt have the Awesome Ego to proclaim philosophies straight to peoples faces like Might and Wataru.
- Ill Boy: After regaining the memories of his true identity, Iori revealed to X-Cross members that he was originally a boy who was physically weak, and prone to sickness. Which greatly surprised them.
- I Choose to Stay: Chooses to stay in Al-Warth in both endings to tie up some loose ends rather than return to his and Amari's Earth.
- Promotion, Not Punishment: When initially recaptured by the Keepers, Iori is given a promotion in exchange to give Hopes back to the facility. It only lasts for a minute or so before he runs away again.
- The Runaway: Of the vagrant runaway type. Iori left his allegiance behind in questioning said allegiance, and in search of the truth, both of himself and the world.
- Ship Tease: Whether or not he's the protagonist, the members of X-Cross will be under the impression that he has a crush on Amari. If Amari is the protagonist, he will pull a HeelFace Turn to protect her.
- Vitriolic Best Buds: If he's the protagonist, he'll have this relationship with Hopes.
The other selectable protagonist. She is part of the Keepers of Order, and is also known as the 'Aquamarine Sorcerer'. She is a proper lady with a serious attitude, but also sometimes a bit timid. However, she has a strong sense of determination at her core, and wishes to be free to grow as an individual. Amari goes on a journey to find her purpose in life.
- Alliterative Name: Amari Aquamarine. Even her real name is one: Amari Amano.
- Badass Adorable: She's a sweet girl decked with fluffy cute outfit (her hair band even makes it look similar to cat ears) and has a slightly timid and unsure self, combined with a cute and soft voice. And she's also capable to kick copious amounts of asses via her magical prowess.
- Brainwashed and Crazy: When initially recaptured by the Keepers, Amari ends up being brainwashed into being a loyal servant of Ende once more. Fortunately, it doesn't last long, and she comes back to the group, with a new attack for Xelguard.
- Desperately Looking for a Purpose in Life: Her starting trait. In the end, she finds her purpose.
- Dude Magnet: If she's the protagonist, then her main romantic arc is with Hopes, Celric falls for her, and she gets enough ship teasing with Iori to make Hopes openly jealous.
- Evil Sounds Deep: Unlike Iori, whose voice is the same either way, Amari's voice as the rival is noticeably deeper than as the protagonist.
- Fake Memories: Her real name is Amari Amano, an Ordinary High-School Student in her 3rd year who lived from a world without Humongous Mecha with her parents and older sister. One day, she and her classmate Iori were brought over to Al-Warth and inducted into the Keepers of Order, complete with false memories of training there for several years.
- Gainaxing: As is fitting for a Super Robot Wars original female character, she has a big bust that bounces in her standard cut-in.
- I Choose to Stay: Chooses to stay in Al-Warth in both endings to tie up some loose ends rather than return to her and Iori's Earth.
- Ship Tease: With Iori, whether or not she's the protagonist. When the members of X-Cross ask if Iori is her lover, she quickly denies it, but no one believes her. If Iori is the protagonist, Hopes asks what his relationship with her is, which makes her blush.
- Who Wears Short Shorts?: Wears a pair of shorts as seen in her standard cut-in.
Hopes / Spero
A parrot-like magical creature created by a Dogma. It can understand human speech, and it follows the protagonist on their journey to expand its knowledge. Hopes also rides in Xelguard and acts as support in battle.
- Ascend to a Higher Plane of Existence: The outcome of the normal route, which players may mistaken as Heroic Sacrifice.
- Barrier Maiden: Hopes true identity is an infant form of a divine beast whose original purpose was to be one of Endes possible new vessels. But Hopes gained more of a self-conscience during his containment within The Order and wished to see the world and learn the meaning of life, hence his plan of escape with the protagonist. As he ventured through the war against Ende, he understands he prefers to be fed with the will and emotions opposite of Ende, and hence, decide to manipulate the nature of X-Cross, along with his divine powers to terminate Ende, and then to preserve, and uphold the world of Al-Warth by becoming their world's highest deity.
- Book-Ends: Narrates the opening of the game. Ends up narrating the same quote in the ending.
- Crazy Jealous Guy: On Amari's route, he's very displeased to be sharing the Xelguard's cockpit with Iori, who he considers a rival for Amari's affections.
- Dub Name Change: His name is changed to its Latin counterpart, Spero, in the English localization, though with Japanese being the only language track, you'll still hear the characters call him Hopes. He's also erroneously still referred to as Hopes in written dialogue at least once.
- Emotion Eater: Hopes frequently comments on the taste of the party's emotions during Vault scenes. Unlike many examples of the trope, he doesn't actually drain the emotions he eats, but he does rely on their presence for sustenance.
- FaceHeel Revolving Door: In Iori's route, he turns to the enemy side at least twice, thrice if counting the True Final Boss fight. Averted in Amari's route, where he stays with you and even becomes playable for one stage.
- Heroic Sacrifice: Attempted in the IF route, he sacrifices himself to save Al-Warth from destruction; except he's got enough fuel to pull off the sacrifice and survive his death.
- Keep It Foreign: The English "Hope" is foreign to the Japanese players but not to other players with English as their mother tongue so the Latinnote equivalent "Spero" makes it foreign for everyone else.
- Meaningful Name: They're both supposed to be a pun on a type of bird, and refer to Hope.
- Obviously Evil: Nearly every single scene that Hopes is in features some sort of blatantly evil musing to himself: the game lays it on thick that he's a villain planning to betray the party in some fashion. In the end, it's all to get even the player to buy into his Zero-Approval Gambit.
- The Plan: In the IF route, he turns against the heroes to utilize X-Cross' positive emotions to fuel Al-Warth without the world needing to create wars and become the world's pillar.
- Spell My Name with an "S": His name was intended to spell as Hopes, but some materials labeled him as Hopps.
- Took a Level in Badass: Stage 39 greatly expands his spirits list to feature a number of new and useful commands. On Amari's route, he's even playable as the main pilot of Xelguard for most of the stage. Then he takes another massive level in badass as the game's True Final Boss in the IF route.
- Took a Level in Kindness: Hopes starts off being about as Obviously Evil as they come, but gradually starts to mellow out over the course of the game.
- Vitriolic Best Buds: If Iori is the protagonist, they'll have this kind of relationship. This is made especially clear on Stage 26, as from that point on, while Hopes will still refer to him as "Master," he stops using formal speech when talking to him, in sharp contrast to his behavior. They eventually end up with approximately the same relationship on Amari's route, though heavier on the vitriol.
- Zero-Approval Gambit: Though admittedly it was more "3 approval gambit" but his entire plan in the True Final Boss fight relied on him turning against the heroes to make them display enough love, courage, hope, and friendship that those positive emotions would be able to become the new foundation of Al-Warth's existence. The only ones who could tell, hence the "3", were Lelouch, C.C. (the former pulling off his infamous "Zero Requiem"), and the protagonist.
Keepers of OrderA society of mages dedicated to enforcing order and justice in Al-Warth, the closest thing it has to an international police organization. The Keepers worship Ende, creator of Al-Warth and God of Wisdom, whose blessing grants them the ability to use magic spells called Dogmas.
- Brainwashed and Crazy: It's implied that most if not all of the Keepers were kidnapped from other worlds and implanted with Fake Memories to make them believe they were Al-Warth natives who'd been with the Keepers for years. The brainwashing gets less and less subtle over the course of the game as the facade of the Keepers starts to break down together with Al-Warth itself beginning to unravel.
- Clock Punk: Their mechs and magic are both clockwork themed.
- Crippling Overspecialization: Compared to the protagonist, who can use wind, fire, storm, and light Dogmas in battle along with an eventual Yin-Yang Bomb, the typical Keeper fought in battle only knows how to cast Tonitars and Torrent.
- Dub Name Change: From the original Order of Mages in the Japanese version to the Keepers of Order in the English version.
- Loophole Abuse: The protagonist manages to elude the Keepers' wrath for a while simply because nobody has ever deserted from them, so there's no rules or explicit punishments in place for doing so.
- Magical Society: Not the only one in Al-Warth, but almost certainly the more competent one.
- Magic Feather: The Keepers use Ende's blessing to channel the atmospheric Od abundant in Al-Warth in order to cast their Dogmas. Neither of these is actually necessary to use Dogmas, and the protagonist must eventually learn to go without both.
- Magitek: They bolster their military strength with Autowarlocks that magnify their pilot's magic and giant animated Golems.
- Mask Power: Low-ranking members are required to wear them, and if you remove it without the approval of your superior, the organization will haul you in for an inquisition. The one who will aggressively go out to nab you will be the selectable protagonist you weren't playing as.
- Villain with Good Publicity: The Keepers are respected all across Al-Warth for the peace and security they help bring, since their dark side is wholly internal, and it's not until late in the game that they start taking actions which go against the reputation they've built for themselves. Their publicity's so good that the protagonist sometimes pretends to still be with the organization when the Keepers aren't around to challenge the assertion.
- Voice of the Legion: Late in the game, the Keepers' voices start to sound...off.
A high-ranking member of the Keepers of Order.
- Ace Custom: His Warth Deenbell is a customized version of the standard Deenbell used by the Keepers.
- Ambition Is Evil: Power hungry for acknowledgment, status, and fame, Celric would do anything to secure his path to be Founder of the Keepers of Order. He overthrows Archmage Keeldin and uses the power of Ende to feed his ego, and his Warth Deenbell eventually goes berserk, along with himself.
- Dying Declaration of Love: If Amari is the protagonist, then he'll say that he wanted her to love him upon his final defeat.
- Green-Eyed Monster: He became infuriated towards the protagonist for becoming the rival candidate for the position of Founder of the Keepers of Order.
- Me's a Crowd: On the final stage of the normal ending, Ende creates a dozen Voodoo Zombie copies of Celric.
- My God, What Have I Done?: If Iori's the protagonist, Celric would explain his actions and apologize to Iori upon defeat, and wished he could've been a better Big Brother Mentor for Iori.
- Redemption Equals Death: In the normal ending, Celric turns back to normal and gives some parting words just before he dies.
- Tall, Dark, and Handsome: He gives a classy and courteous impression to X-Cross members when they met him for the first time. This was likely his original personality, but as soon as he buys into Ende's offers of power, everything goes downhill for him.
- Voodoo Zombie: Due to Ende's success in devouring his goodness and amplifying his ambition, Celric, post death, became Ende's proudest backup vessel, and had intended to use him as a new body once Ende's current form is of no use. X-Cross managed to stop him before it was too late.
The current highest ranking member, and overseer of the Keepers of Order. Whenever there is disorder within their ranks, members who contribute to said disorder are brought over to him for an inquisition.
- Gone Horribly Right: Keeldin motivates both the protagonist and Celric to compete as potential candidates for the Founder's seat. The latter eventually kills Keeldin as his ambitions escalate.
- Threshold Guardians: Keeldin stands neutral over the issues the protagonist has brought forth to the Keepers as long as the protagonist can provide a legitimate reason for his or her actions. As the protagonist continues to defy their knowledge, Keeldin proceeds to consider the protagonist to be a candidate for the Keepers' top spot, which will surpass himself-The Founder.
Ende the Devourer
The God of Wisdom worshiped by the Keepers of Order, and the creator of Al-Warth in its creation myth. They mean that quite literally, and Ende's reason for creating Al-Warth in the first place was to feed on the negative emotions of its populace.
- Eldritch Abomination: Pretty much. And like any self-respecting eldritch horror, he plans to travel to other worlds and feast on their emotions.
- Emotion Eater: Unike Hopes, Ende doesn't actually rely on human emotions for sustenance, but likes the taste of them anyway. Also unlike Hopes, he's gluttonous enough to suck them out and leave the victim a soulless husk, and even when he doesn't do that, his favorite emotions are hate, fear, and anguish.
- Final Boss: Of Super Robot Wars X's Normal Route. That being said, in the IF route, Hopes seizes control of him to become the True Final Boss.
- Fisher King: Al-Warth came into existence when Ende recognized it did. When he decides he doesn't care whether or not it exists anymore, the world begins to unravel.
- Hybrid Monster: He's part dragon, part beast, and has a gigantic tree on his back. The game's library notes that it's the dragon part that's really him; the beast and tree parts were other creatures that Ende assimilated into himself when he took control of the combined body.
- Interface Spoiler: The fact that "Steel Warriors" by Jam Project isn't playing in the background in the IF Route Final Boss fight suggests there's one more boss to fight.
- Man Behind the Man: Ende was the one meddling with the three worlds for the past 3000 years because he wanted to feed on the resulting negative energies. He even co-opted Black Noir to use as an administrator for those worlds, but Black Noir was unaware of his true purpose. Hell, the latter even believed he was the former!
- Too Spicy for Yog-Sothoth: He feeds on despair, anger, hatred, and other negative emotions. Love and other positive emotions, however, taste horrible to him in large doses, and he prefers to use them as something of a minor spice.
- When Trees Attack: He has a gigantic tree on his back.
