Thirteen's physical appearance is unknown because his entire body is hidden underneath his hero costume. The costume consists of a white space suit, a black helmet with white eyes and a pair of yellow boots.
Thirteen is a wise, well-mannered person that knows very much about the concept of how Quirks are an irrefutable part of the world and how they can be used for both saving and killing people. As a rescue hero, Thirteen has displayed how passionate he is about saving people through his teachings. He even developed his own training facility in the U.S.J to train future heroes in search and rescue tactics.
Thirteen has also shown himself to be very brave. Despite not being a combat type, he does not hesitate to use his Quirk to fight against Kurogiri in order to protect his students.
A year prior to starting his teaching career, Aizawa was called into a meeting with Best Jeanist, Manual, Desutegoro, Snipe, Thirteen, Endeavor, Air Jet, Midnight, Ingenium, and Gunhead. He was there with an unnamed police officer to speak about the unwilling civilians injected with Trigger. The officer explained that the people in question were more of victims than villains. Endeavor argued that any public use of a quirk is illegal and that they should treat them as villains and let the police investigate the backgrounds of future captures. He said this is the only way to protect the innocent while not risking themselves through hesitating every time they see a new enemy. All Might, who was not present, had his reply to the problem delivered by Naomasa. He stated that he would assess the situation at the scene more carefully because as heroes they must not bring harm to innocent citizens. This was in direct opposition to Endeavor's answer greatly angering him.
When Class 1-A is brought to the Unforeseen Simulation Joint, Thirteen explains that they will train there because the facility simulates all kinds of disasters and accidents. Class 1-A's homeroom teacher, Shota Aizawa asks Thirteen where All Might is, and he replies that he was doing too much hero work to make it on time. Before rescue training begins, Thirteen speaks to the students about the dangers of Quirks and why they need to be regulated as well as how the students will now be training to use their Quirks to save people. Thirteen concludes his speech by saying he hopes everyone will understand how to wield their Quirks in rescue situations by the end of the exercise and thanks to the class for listening.
However, before the training exercise begins, villains appear through a Warp Gate. Shota tells Thirteen to protect the students and leaps into action. While trying to lead the evacuation for the students, Thirteen is confronted by Kurogiri, who asks where All Might is.
Thirteen tries to sneakily use his Quirk while he is talking, but he is unable to when two of the students attack Kurogiri. Katsuki Bakugo and Eijiro Kirishima seem to land an attack, but Kurogiri remains unphased. Thirteen pleads for the tandem to move out of his way, but Kurogiri capitalizes and uses his Quirk to separate the class by teleporting the students to several different places within the facility. Thirteen remains at the entrace plaza along with Tenya Iida, Ochaco Uraraka, Hanta Sero, Rikido Sato, Mina Ashido, and Mezo Shoji.
Thirteen commands Tenya to use his Quirk to run to the school and alert the faculty of the attack because one of the villains is jamming his communications. Kurogiri overhears his plan and prepares to stop them, but Thirteen uses his Quirk to suck his mist body into a black hole.
Kurogiri commends Thirteen on his powerful Quirk, but also comments that he has little fighting prowess before he opens a warp-gate behind them and in front of him so that Thirteen ends up using his Quirk on themselves. Half of Thirteen's suit ends up disintegrated by Black Hole and he is incapacitated.
Eventually, All Might arrives, as well as the U.A. High School faculty members called by Tenya. They repel most of the villains, forcing Kurogiri and Tomura Shigaraki to try and escape. Thirteen is helped to his feet and he tries to stop them from using his Quirk, but they teleport away. Afterwards, Thirteen is brought to Chiyo Shuzenji to be healed. Detective Naomasa Tsukauchi confirms that he has recovered from his injuries when he informs the students of his condition.
During the U.A. Sports Festival, Thirteen spectates the events in the faculty section of the stands. As the battle between Izuku Midoriya and Shoto Todoroki begins, Thirteen asks All Might if Izuku and Shoto are the ones that jumped in to save him at the U.S.J, which he confirms.
Prior to Final Exams at the end of the first years' first term, Thirteen meets with his fellow faculty members. They discuss changing the finals format from facing robotic villains to fighting against the teachers. Thirteen comments that this may be too difficult for the students, but they all ultimately agree on the change. Thirteen joins the teachers at the Final Exams practical portion test site to meet Class 1-A. Thirteen is placed against Ochaco and Yuga Aoyama.
In their battle, Ochaco and Yuga reach the escape gate but before they can go through it, Thirteen stops them with his Quirk. The duo holds onto a guardrail to avoid being sucked in. Yuga fires his Navel Laser from his knees (thanks to his hero costume) at Thirteen, but the attempt fails as Thirteen easily sucks in the laser. Ochaco randomly lets go of the guardrail (as the conversation between the two is unknown to Thirteen) and Thirteen stops using his Quirk to protect Ochaco from being turned to dust. Facing Thirteen directly, Ochaco uses the combat skills learned from interning with Gunhead and manages to pin down and handcuff Thirteen. Thirteen questions where her skills came from and the two students pass the practical test.
