|Let's have them show...whether they're suited to rule over the human race. They will be the ones to rule over that decision.|
|— Pixis considers an insurrection|
Dot Pixis (ドット・ピクシス Dotto Pikushisu?) is the Garrison's Chief Official of the Southern Territories (南側領土最高責任者 Minamigawa Ryōdo Saikō Sekininsha?, also translated as "Highest Ranking Commander of the Southern Territory"), which includes Trost District. He is often simply addressed as "commander" (司令 Shirei?). In matters of defense, he is given full authority.
Pixis is a bald man with a structured build. He has a distinguished mustache, with light skin and notable wrinkles under his eyes. As a commander, he also wears a purple bolo tie, much like his fellow commanders Hange Zoë and Nile Dok. As a high ranking Garrison officer, he is only seen wearing his Garrison uniform paired with a white button-up shirt and a red sash with gold trim.
Pixis is an eccentric man. While observing Titans breaching Wall Rose, he said he would not mind being eaten by a Titan if "it happened to be a stunning beauty." He retains a calm, and light-hearted demeanor, even in the midst of chaos, and he understands the strife and suffering of others, as he is seen allowing soldiers who wanted to leave because he understands the extreme amounts of terror and fear in those soldiers. Yet, Pixis is an effective leader, as seen when he quiets all the soldiers attempting mutiny and successfully convinces them to continue fighting to retake Trost District. He is an expert strategist and is able to gauge a situation carefully, but also knows when to take risks, which lead to his decision to trust Eren Yeager to stop the breach. He is a man who makes smart choices, putting Ian Dietrich in charge of the alpha squad protecting Eren proved to be a wise move as Rico Brzenska and Mitabi Jarnach both called that they should give up on the operation, which Ian denied, that eventually led to being a success.
After it is discovered that Eren Yeager can transform into a Titan, Eren is sentenced to death. Pixis, however, happens to be nearby when Armin Arlert gives a passionate speech in defense of his friend, vouching for the strategic and tactical benefits that he can bring to turn the tide of the battle. The officer in charge, Kitz Weilman, is not swayed, but as he is about to give the kill order, Pixis stops him, believing Armin's words.
Pixis brings the three soldiers on top of Wall Rose and clears up the matter of Eren's transformation by saying he will see the proof in Eren's basement. He questions Armin about his plan to use Eren's Titan form to seal the hole in Wall Rose and is so encouraged he decides to use it. He calls up his staff officers to begin planning for the assault. However, the Garrison, already extremely low on manpower and morale after the evacuation, is in no condition to fight again and many soldiers attempt to mutiny in order to spend the little time they have left with their families. In order to give the soldiers hope, he introduces Eren as being a part of a secret government experiment to turn humans into Titans to fight them on equal footing. Unsurprisingly, Pixis is not taken seriously and soldiers turn to leave, some even fighting each other. Finally, he gives an order to pardon all deserters, which shocks higher ranking soldiers. However, he states that by leaving, they will put their families at risk and expose them to the same terror that has paralyzed themselves. This argument convinces the soldiers to reassemble their ranks and begin the operation.
Atop the Wall, Pixis is seen talking to another soldier who informs him that they have managed to lure the Titans into the corner of the town but about 20% of the soldiers have been lost in the process. Pixis responds by saying that they did not lose them but they were sent to their deaths by him and to give humanity a chance to survive he was willing to become a butcher. Upon reaching the boulder, Eren transforms and loses control over his Titan form and incapacitates himself. Rico fires a red signal flare to announce the mission's failure. Despite of several soldiers' requests to give a withdrawal order, Pixis allows for the operation to continue, having faith in the alpha squad soldiers. Later when Eren manages to regain his consciousness and successfully seals the breached gate, Rico fires off a yellow signal flare to announce the operation's success. At the sight of the mission's success, Pixis orders for reinforcements to retrieve the alpha squad.
Pixis later appears when he is being given a report by Hannes when a member of the Survey Corps informs him and the others about Wall Rose being supposedly breached for the second time by the Titans. He later appears drinking on top of Wall Rose when Anka, one of his escorts, scolds him for drinking and makes it known that she does not want to take care of him, which Pixis would be fine with because he thinks she is a beauty. She gives a report that Titans have stopped appearing and only a few appeared anyway. Pixis surmises that there might be no breach in Wall Rose given the lack of Titans. Erwin Smith then appears and Pixis congratulates him on capturing the Female Titan. He hopes this will force the government to start thinking and Erwin replies that they already have, and the Military Police Brigade present with Erwin are proof of that. A Garrison member then arrives to inform him there is no breach, and that three more humans who can turn into Titans have been identified: Reiner Braun, Bertolt Hoover, and Ymir.
Pixis next appears with Levi and a convalescent Erwin, who is recovering from the loss of his right arm during the battle against Reiner, Bertolt, and Ymir. They discuss the supposed breach in Wall Rose, when Hange and Connie arrive and bring them the news that there was no breach and that the Titans were the same inhabitants of Ragako who were transformed in an unknown way. Hange shares the theory that all Titans may have been humans once, and Pixis suggests that the only difference between humans with the power of the Titans and regular Titans may be that the former have not assimilated the human inside. Hange and Levi then inform them that Eren and Historia have been sent into hiding for their protection.
He is seen again when Erwin Smith proposes overthrowing the government. Pixis is sympathetic with Erwin and agrees that something must be done, but he also exclaims being an old soldier and how he will not lead his soldiers against each other. He agrees to help if Erwin's intention are noble but also warns that he will personally deliver Erwin to execution if he is acting wrongly. He then discusses how people have put up with the King because they all share the same fate in the Walls, and that any attempt to forcefully remove him from power would involve tremendous violence. Erwin believes that the government wants Eren in order to use his abilities to control humanity; Pixis believes that they might be able to hand Eren over since they all share the same fate. Erwin disagrees and Pixis wonders how they will carry out the revolution, to which Erwin replies that they will replace the King with Historia Reiss, a descendant of Rod Reiss, the true ruler of humanity. It is later revealed by Erwin that Pixis refused to help in the revolution.
Pixis is present at the hearing of Erwin Smith. Just as the situation looks bleak, Anka reveals that Wall Rose has been breached. Pixis begins to give evacuation orders for the refugees but is stopped when the capital officials decree that no refugees will be allowed to enter Wall Sheena. This shocks the small military crowd inside the room, particularly Nile Dok. Anka leaves the room and moments later, Darius Zackly appears within the room. He reveals that the breach of Wall Rose was a ruse and Pixis announces everyone's role in rooting out the corruption present within the royal government. Erwin is then released and the officials are then taken into custody for valuing their wealth over the lives of the people.
It is later revealed that Pixis stated to Erwin that he would only participate in the revolution if the King and his lackeys attempt to sacrifice half of the population in order to save themselves (and the nobles from starvation) if Wall Rose were to be breached. If the King and his nobles did not attempt to do so, then Pixis would immediately confess to acts of treason and offer his life. However, the King and the nobles attempted to lock out half of the population.
Later, Pixis is present at the coronation of Historia Reiss, and alongside the other Military leaders, bows down to her.
As Armin Arlert explains his plan for victory against the Colossus Titan to Eren, Pixis sits with the other military leaders drinking tea and worrying if the operation to retake Wall Maria and humanity's land will be successful.
Pixis attends the meeting to debrief the survivors of the mission to reclaim Wall Maria. When it is suggested that the information recovered from Eren's basement be kept from the public, Pixis argues that deceiving the public will make the current government no better than the one they overthrew.
The following year, Pixis attends another meeting to discuss Zeke Yeager's request for an alliance. Despite some officials wanting to go against the plan, he says they should hear what Zeke has to say before forming an official decision. Later, when meeting with the delegation from Hizuru, Pixis agrees that Paradis is extremely behind the other nations of the world and advises to some of the more skeptical officials present that they agree with the alliance.He then meets with the Anti-Marleyan Volunteers and receives a box of Titan serums from Yelena that were stolen from Marley. Despite knowing that it will be difficult to duplicate without any resources, Pixis thanks them for their efforts in securing the samples. He acknowledges that Yelena and her group have given them hope and lead the way to freedom with receiving nothing from Paradis in return. Despite this, Pixis asks that Yelena and her group turn a blind eye for now on Paradis' weaknesses and insists that for the time being, Zeke will have to be in custody.
Pixis later visits Yelena in her cell, accompanied by Anka. He reaffirms that Paradis is grateful for the aid the Volunteers had given them, and he appreciates the transparency Yelena had shown in opting to have her actions recorded and reviewed. Pixis explains, however, that this effort to appear innocent is what had raised the military's suspicion anyway. Particularly, misgivings were raised when ten months ago, there was a sudden change in the soldier responsible for keeping an eye on her to Floch Forster, currently detained for divulging sensitive information. He reads that Floch had taken her to a private lodging nearby to Eren's residence, around the time Eren had begun to take more unauthorized actions. Having finished reading off his suspicions, Pixis sits down, and admits he is glad to have the opportunity to talk with such a beautiful lady.
To Pixis's surprise, Yelena immediately admits to meeting with Eren and apologizes for keeping it hidden until now. Yelena claims that she only advised Eren to do something to energize the military's efforts, but Pixis points out that if that were the case she could have just talked to the military directly. After hearing that the Volunteers were not allowed to meet him even in public, Pixis wonders if Yelena possibly losing the trust of Paradis was worth going behind their back and seeing Eren in private. He accuses Yelena of manipulating Eren towards Zeke's will, but Yelena passionately denies any ulterior motives other than wanting to meet Zeke's brother due to her own curiosity and a desire to help Eldia. Pixis tells her that he wants to believe that, but tells her that she is terrible at lying.
After hearing that Darius Zackly was assassinated, Pixis is named as the acting Commander-in-chief of the military. After listening to Hange's theory about the group's ulterior motive, he asks how many are aware of Zeke's location. He orders the three soldiers not currently with Levi be brought in and asks Nile Dok and several Miltary Police soldiers to check that Historia's residence is secure. Ordering both areas safeguarded, Pixis orders Armin to use his Titan ability to fortify the area if needed. He then reveals that he plans to surrender to the rebel group; while the others are stunned by this, Pixis clarifies that he will not submit to the Yeager brothers but hope to be able to use Zeke's location as a means to negotiate with them. After dismissing the soldiers, he apologizes to Kiyomi Azumabito who was present during the exchange. Knowing they can not effectively protect her, Pixis tells Kiyomi to stay in the harbor for her own safety.
Despite his own words, Pixis would begin searching for an opportunity to abduct Eren in order to confiscate the Founding Titan. After Zeke activates his scream from the Titan Forest, Pixis suffers a reaction alongside those who had drunk Marleyan wine. Immediately after, Pixis comes to the realization that Zeke has snared them.
As expected of the leader of the Garrison, Pixis is highly intelligent and one of the most important members of the army.
Dot Pixis's statistics :
- Erwin Smith - Pixis shared a similar view with Erwin that the current government was corrupt and unsuited to rule humanity, but that he would only help if his intentions were noble. Eventually, Erwin's plea and the resulting actions of the government would be enough to convince Pixis to participate. He also mourns Erwin when it's revealed he died in the process of retaking Shiganshina District.
- Darius Zackly - As his direct superior, Pixis initially had a good deal of respect for Darius Zackly. Despite this, he always had an inkling that Zackly was motivated by a desire for vengeance, a prediction that was proven in the coup d'état. Pixis has stated that he does not understand Zackly, and would have fought against him if his revolution was against humanity's interest. After Zackly's assassination, Pixis makes the decision to disregard his murder to prevent further conflict with the Yeagerists. Considering the alternative, he calls this price "a cheap one to pay."
- Kitz Weilman - As a Captain of the Garrison, Pixis has some degree of respect for Kitz. However, he does note that Kitz is weak-minded and tends to act rashly in stressful situations.
- Nile Dok - Pixis and Nile Dok have not been seen interacting much, but it is believed they have a mutual respect for each other as heads of their respective branches of the military. They seem to cooperate well in the military government.
- Yelena - Over the course of three years, Pixis mentions that Yelena and her group have done so much to help Paradis with getting nothing in return, showing that he has some amount of respect for her. He also shares her wish that the Eldian people will have a bright future where they can all be reunited as one. Despite this, Pixis has his suspicions over Yelena, opting to have her placed under house arrest due to fears of a hidden motive. Still though, Pixis seems to like her on an individual basis, complimenting her on her actions and appearance; however, he begins to distrust her ultimate motives after she reveals that she went to see Eren without authorization from Paradis.
- The name "Pixis" may refer to the constellation "Pyxis Nautica" - Latin for "The Naval Compass."
- In 2010, Isayama posted a blog post admitting that Dot Pixis was modeled after General Yoshifuru Akiyama, a general in the Imperial Japanese Army, to whom Isayama said "I respect for leading such a simple and frugal life." This brought a large controversy and even death threats against the mangaka that lasted for years (and may still continue to this day) from sectors of the population where Yoshifuru is deeply hated. 
- In an issue of Bessatsu Magazine, Isayama revealed that Pixis is married and has children.
