This article outlines the characters of Shogo: Mobile Armour Division.
 Main Characters
 Sanjuro Makabe
The protagonist of the game. Sanjuro is a sarcastic, somewhat angsty U.C.A soldier (ranked at Commander) with a serious disrespect for authority, which earns him the ire of his commanding officer Admiral Akkaraju. He is still recovering emotionally from the death of his lover Kura, although that doesn't stop him from having a relationship with Kura's sister, Kathryn. He was orphaned at a young age and he and his brother Toshiro were brought into a U.C.A military academy, where he met Kura, Kathryn, their father, and Baku. Sanjuro had the gift of fine social skills, leading him to be well liked by his class-mates. He had a special "Love-Hate" relationship with Kura as a young man, the two constantly teased each other in what was actually primitive flirting which eventually turned into full blown love.
After Toshiro, Baku, and Kura's supposed deaths he was diagnosed with post-traumatic stress disorder, in part due to some considering him responsible. He took consolation in Kathryn, which eventually lead them to love each other. At the end of Shogo he is left to deal with Kura and Kathryn, who are both competing for his affections, as well as presumably reacquaint himself with his brother and come to terms with the death of Hank. An older design document for Shogo had his last name as "Takeshi" and showed that the reason Sanjuro was the only one known to survive the terrorist attack was so that he could suffer through the emotional trauma caused by the event, to pay for his assassination of the Fallen leader Ivan Isarevich. There is no evidence against this information in the final product, other than the change in last name, though no mention of it per say.
 Toshiro Makabe
Sanjuro's brother, who disappeared during a Fallen terrorist attack several months prior to the events of the game. It is revealed that Toshiro is in fact the Fallen leader, Gabriel. After the attack, he was captured and taken over by the Cothineal, becoming her human avatar. In childhood he was more effected by his parents deaths than his brother, leading him to stay reclusive and prefer the company of his own imagination. This lead him to have a quiet and more internal personality. He also grew a great jealously over his brother's popularity, heightening after Sanjuro and Kura fell in love. In the first ending it is depicted that Toshiro is removed from Cothenial forcefully and undergoes treatment for his experiences. In the second it is told that he remains as Ambassador to Cothenial, presumably regaining more self-control.
In an older design document for Shogo it is shown that Cothenial herself staged the terrorist attack to draw the team containing Toshiro to the where she could manipulate him. He, like Ivan Isarevich, had a mind capable of handling Cothenial's orders and his emotional instability caused by his resentment and jealously of his brother's popularity made him easier to control. Cothenial took over Toshiro's mind with much more force than Isarevich as her cause was more desperate and the Fallen needed a leader. She sent him against his friends, taking on Baku as his right hand man and leaving Kura to die, as her loyalty to Sanjuro made her useless as a pawn. Sanjuro was only allowed to escape to allow him to suffer through the emotional trauma caused by the event, in vengeance for the death of Ivan Isarevich. There is no evidence against this information in the final product, though no mention of it per say.
 Baku Ogata
Sanjuro's childhood friend, Baku also vanished during the Fallen attack along with Kura and Toshiro. Baku became Gabriel's right hand minion Uziel, and holds an insane hatred for Sanjuro. Baku was often beaten upon by his classmates as a child, partially due to his shortness and meek personality. Baku also grew a crush on Kura but never was brave enough to tell her, particularity after she entered into Sanjuro's affections. He is killed by Sanjuro in the first ending, while his future is rather ambiguous in the second ending, though his mental state is questionable given Kura's quote of "Baku's insane, I don't know whats wrong with him, but he's dangerous." However, it might not actually be a mental affliction but just an affectation of Cothenial's control.
 Kathryn Akkaraju
The communications officer for the U.C.A.S.F Leviathan (listed as Lieutenant Commander), Kathryn is Sanjuro's primary radio contact as well as his girlfriend. She is responsible for giving Sanjuro most of his mission briefings and objectives over the radio. She seems more emotional and kind-hearted than her tougher, tomboyish sister, Kura. She like Sanjuro is described as someone who gets on the nerves of those of authority, but is too valuable to lose. After the death of her mother in combat, she swore of violence. However to keep with her training, family history, and friends she entered the U.C.A as a communications officer. After the supposed deaths of Toshiro, Baku, and Kura, she took comfort in Sanjuro as he did likewise. This comforting eventually grew into love. She is initially disgruntled after finding out about Kura's continued life, worried that it would mean that Sanjuro would leave her. She later apologizes for this to Sanjuro though she is later infuriated with Kura after she makes a suggestive remark to Sanjuro. She was voiced by Kathy Levin, who also voiced in Blood II: The Chosen.
 Kura Akkaraju
Sanjuro's previous girlfriend, Kura (ranked at Commander) was assumed to have been killed in a Fallen terrorist attack several months before the events of the game. As it turns out, she is alive and well, having been investigating the Fallen as an undercover spy. Kura resurfaces midway through the game, revealing key information about the true nature of the Fallen to Sanjuro, and helping him in his mission. Rather then turn away from violence after her mother's death as did her sister, Kura grew even more interested in military life. She also blamed her father, who held back from attempting to save his wife due to the need to stick with his orders. Kura saw this as cowardice that lead to her mothers death. Kura was dismayed to discover Sanjuro's relationship with Kathryn, feeling more angry at Kathryn than Sanjuro. The end cutscene depicts Kura and Kathryn chasing after each other, presumably over Sanjuro. A description for the canceled Shogo expansion pack Shugotenshi suggested that she is worse effected by the death of her friend Hank than the others, it is also said that she would be a playable character in the expansion. She was voiced by Kari McGee.
In an older Shogo design document it is further elaborated about what happened to her during the terrorist attack and how she met Hank. While Cothenial took Toshiro to be her general and got Baku to be Toshiro's right hand man, Kura was left to die in her MCA. Her loyalty and love of Sanjuro would have made her hard to manipulate and thus made her useless. She didn't die however, as Hank Johnson found the wrecked MCA's of the U.C.A. strike team and found Kura unconscious in her own MCA. Hank took her to the geological research base where he was stationed and he and his wife attempted to nurse Kura back to health. She had no major physical injuries but Cothenial's mental powers had left her deeply afflicted. While Hank and his wife where discussing who tell to get her help she regained consciousness and told them to reveal her continued life to no one. Even though they doubted her mental ability to decide on such matters, they honoured her wishes. Over the next few months Kura overcame whatever demons where tormenting her and made various unexplained trips into Avernus, upon questioning Kura admitted that she was spying on the Fallen, to which Hank replied by demanding the she let him help her. There is no evidence against this information in the final product, though no mention of it per say.
 Nathaniel Akkaraju
The leader of the U.C.A forces on Cronos (as an Admiral), and the father of Kathryn and Kura. The Admiral harbors a burning hatred for the Fallen, supposedly because of Kura's death at their hands. As it turns out, however, he knew perfectly well that Kura was alive and unharmed all the time. Thus, his harsh behavior and ultimate decision to commit genocide against the people of Cronus are left somewhat unexplained by the plot. After the death of his wife in combat previously, Nathaniel hid himself behind his job, in part due to Kura blaming him for it. Due to his actions of taking his ship the U.C.A.S.F Leviathan under military control despite orders from U.C.A High Command, he was court-martialed in both Shogo endings. In the first ending, it is suggested that little would come of it, the other is left ambiguous. He was voiced by Ted D'Arms, who also played Gideon in Blood II: The Chosen.
 Hank Johnson
A friend of Kura's, Hank is a citizen of Cronos who assists Sanjuro through much of the game. He is eventually executed by Ryo Ishikawa. He had always wished to enter the U.C.A military as a pilot and be a "hero", however he never got past the physical tests. This was due to an untreated genetic condition that robbed him of much of his endurance. Instead he married and worked as a geologic researcher (particularly geothermal studies) outside of Avernus for the Armacham Technology Corporation, still wishing to fight. He met Kura in the underground during her stay as a U.C.A spy, this friendship lead them to assist each other.
An older Shogo design document elaborates on how he found Kura and how he got involved in the Cronian Revolution. While working in the geological researcher he found the wrecked MCA's of a U.C.A. strike team and found Kura unconscious in her MCA. Hank took her to the base where he was stationed and he and his wife attempted to nurse Kura back to health, where she suffered weird psychological afflictions. While Hank and his wife where discussing who tell to get her help she regained consciousness and told them to reveal her continued life to no one. Over the next few months Kura recovered and made various unexplained trips into Avernus, upon questioning Kura admitted that she was spying on the Fallen, to which Hank replied by demanding the she let him help her. There is no evidence against this information in the final product, though no mention of it per say.
 Ryo Ishikawa
The acting head of Shogo Industries' Cronus division, son of Shogo Industries' president, Shinobu, and arguably the game's main antagonist. He is manipulating all sides in the conflict in an attempt to destroy the Fallen and all of the factions so that he can exploit Cothineal. He is the final enemy fought in the game in both endings, though is significantly easier than Gabriel in the second ending.
An older Shogo design document elaborates on Ryo's manipulations and motives. He immediately saw the Cronian Revolution as a chance for Shogo to gain control of kato mining. There were many groups with stakes on Cronus, some such as Armacham and Andra Ryo considered only minor threats, however he knew that he would have to deal the the UCA, CMC and the Fallen. After researching the situation on Cronus, Ryo met with Ivan Isaravich who was the leader of the Fallen. There they made a pact where in exchange for lessening the amount of kato mining, the Fallen's main objective, Shogo would become the sole distributor of the biological ore. Cothineal knew that Ryo would eventually betray the Fallen, and that his motives were only to make kato more scarce to drive up the price, but she figured that the short term benefits justified the alliance. Shogo started to supply the Fallen with information, weapons, resources and technology, all without any other group suspecting anything. Ryo was even clever enough to make sure that Shogo get raided by the Fallen just as much as anybody else. Ryo was furious when he heard that Isaravich had been assassinated by the UCA, so he found out who was responsible, Sanjuro, and plotted to make him suffer. This is why Sanjuro was left alive after his team was attacked by the Fallen, so he would have to face the mental demons caused by the traumatic incident. Gabriel, the new Fallen leader, then contacted Ryo and changed the deal. In response Ryo than planned to gain control of Cronus' kato by capturing Cothenial and housing her in a stasis field generator on a space-based platform where they would test and exploit her. There is no evidence against this information in the final product, though no mention of it per say.
A colossal underground creature that is actually the source of Kato. She was responsible for the creation of the Fallen and the possession of Toshiro and Baku. In either endings humanity negotiates with Cothenial though in the second ending Cothenial is injured by Sanjuro while freeing Toshiro by force. Cothenial seems similar in design to The Ancient One, the final boss of Blood II: The Chosen.
An older Shogo design document elaborates more on Cothenal's past and activities during the Cronian Revolution. Ivan Isaravich, the Fallen leader, met with Ryo Ishikawa. There they made a pact where in exchange for lessening the amount of kato mining, the Fallen's main objective, Shogo would become the sole distributor of the biological ore. Cothineal knew that Ryo would eventually betray the Fallen, and that his motives were only to make kato more scarce to drive up the price, but she figured that the short term benefits justified the alliance. Shogo started to supply the Fallen with information, weapons, resources and technology, all without any other group suspecting anything. After Isaravich was assassinated, Gabriel, the new Fallen leader, then contacted Ryo and changed the deal. So Ryo thought up a new plan and weakened the CMC by convincing or bribing officers to join his side. Having taken care of one foe, Ryo than planned to gain control of Cronus' kato by capturing Cothenial and housing her in a stasis field generator on a space-based platform where they would test and exploit her. There is no evidence against this information in the final product, though no mention of it per say.
 Minor Characters
 Ivan Isarevich
A former leader of the Fallen that was assassinated by Sanjuro, Toshiro, Baku and Kura during the mission were all but Sanjuro were supposably lost. Ivan was described by Ryo as "an up and coming tyrant". After his death Gabriel (aka Toshiro) took control of the Fallen. In an older design document for Shogo Isarevich is described in more noble fashion as an environmentalist who was concerned that such a high rate of kato mining would eventually lead to it running out. He was charismatic, respected and had a strong enough mind to stand being controlled by Cothenial, the first person of the kind she found. Isarevich furiously campaigned to the CMC to lower the rate of mining to no avail. Eventually Cothenial gave him new orders, to form the Fallen and commence terrorist attacks against the CMC. When the CMC tried to declare Cronus independent and the Cronian Revolution started the Fallen were able to grow in strength. Ryo, trying to meddle in the conflict for his own ends, secretly met with Isarevich and feed the Fallen information, technology and resources. There is no evidence against this information in the final product, assuming that he only grew to fit Ryo's description over time, though there is no mention of it per say.
 Lieutenant Dussault
A lieutenant serving under Sanjuro during a mission on Cronus taking place in the first level and most notably the evacuation off planet. He is referred to merely as "Shock Trooper" in the game's files and is probably named after Mike Dussault, the head engineer of the LithTech engine.
 Lieutenant Cloud
Head of the U.C.A.S.F's "Strike Force Carnivore", he leads a team against the Fallen inside the old C.M.C headquarters, assisting Sanjuro's mission. While Sanjuro is trying to escape the facility after the mission encounters complications the Lieutenant and the entirety of Strike Force Carnivore is overwhelmed by the Fallen.
 Captain Evans
The pilot in charge of flying the LZ Minotaur shuttle. He drives Sanjuro down to Cronus from the Leviathan early in the game. He is referred to merely as "pilot" in the game files. He might be named after Israel Evans, the LithTech motion capture actor.
 Samantha Sternberg
A young, blue-haired woman soldier fighting for the Fallen, Samantha attacks Sanjuro at several points in the game. Despite apparently being blown up each time, she somehow manages to return again to challenge him. She plays no significant role in the story, though some people claim that she is supposed to be Sanjuro's first girlfriend and so add a new dimension to the relationship. She might have been voiced by Lynn Rott, who also voiced in Blood II: The Chosen.
A bartender on board the Leviathan, that Sanjuro attempts to gain a drink called the "Red Claw" from at two points in the game. She always refuses for one reason or another such as "your on duty" or "I think you need a clear head". In the end cut scene Sanjuro blows her up after she refuses to give him the drink yet again, however whether or not this is canon is disputable.
 Sanjuro's Squad
Sanjuro is given command of a squad of forces at the beginning of your mission to infiltrate Avernus and eliminate Gabriel, as you are also accompanied in the first level by the likes of Lieutenant Dussault. They accompany you and cover you while you do the hard work, such as one point where you have to go down into a pool of water to hit a gravity switch to lower bridges for your squad mates. They do not follow you into Avernus. They are an early example of squad artificial intelligence in first-person shooters but suffer from the problem of somewhat limited responsiveness that plagued this technique during the 1990s. This is shown such by the player being able to easily outrun and lose them which is actually remarked upon in the game by Kathryn if this happens:
Kathryn: Aren't you forgetting your squad mates?
Sanjuro: Actually I'm ignoring them.
It should be noted however that they arguably function better then Maurice and Toshi do later in the game, and all in all are probably implemented better then other classic examples of failed squad artificial intelligence such as in John Romero's Daikatana.
 Maurice and Toshi
Two friends of Hank's that assist Sanjuro inside MCA's when he enters Maritropa. They are an early example of squad artificial intelligence in first-person shooters but suffer from the problem of somewhat limited responsiveness that plagued this technique during the 1990s. This is shown such by the player being able to easily outrun and lose them or, more notably in this case, them dying almost immediately after the level begins. In addition, they have been known to actually shoot Sanjuro if he happens to be in their line of fire. It should be noted however that arguably the squad mates shown earlier in the game function better. If they do manage to survive long enough, they will also be eventually unable to follow Sanjuro due to level obstructions.
 Haddam Family
About midway through the game Sanjuro is stopped by an electric fence in the slums of Maritropa. It is controlled by the Haddam family, Sanjuro talks to Mrs. Haddam and she offers to let him through if he finds her lost cat. If the player does this he enters an extra level where he must fight stragglers who wish to eat the cat, the other option is to kill her and then defeat her husband and forcefully destroy the electrical generator.
