"Space Hero" Thirteen (スペースヒーロー・13号) is a Pro Hero.

Appearance
Thirteen is a large person with an unknown physical appearance due to the fact that their whole body is hidden.

Their hero Costume consists of a space suit, a helmet, and yellow boots.

Despite their thick clothes and large hands, their legs are visibly thin, suggesting that they are actually thin and it is their clothes that are large.

Personality
Thirteen is a well mannered person that knows very well about the concept of how Quirks are an irrefutable part of their world and how they can be used for both saving and killing people, but they are very passionate on saying that Quirks are meant to be used to save people.

History
A year prior to starting his teaching career Aizawa was called into a meeting with Best Jeanist, Manual, Deathtegoro, Snipe, Thirteen, Endeavor, Buster Hero, Midnight, Ingenium, and Gunhead, They were 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 Endeavors answer greatly angering him.

Unforeseen Simulation Joint Arc
Thirteen makes their debut at the Unforeseen Simulation Joint, an area which they said they created to simulate all kinds of disasters and accidents. Shota asks where All Might is and Thirteen replies that All Might was doing his job as a hero and that he could not make it as he was taking a nap. Before the rescue trial could begin, Thirteen makes a speech about the dangers of Quirks being used to accidentally kill people and how Quirks have been regulated and their requirements for usage strictly enforced by the society of superhumans humans. They tell the students to be wary of their Quirks and then tell them that their lesson will be about wielding their Quirks for the sake of human life.

Thirteen ends their speech by saying they hope that everyone will fully understand that their Quirks exist to help people at the end of the exercise and then thanks everyone for listening with Izuku, Ochaco and Tenya applauding them. However, before the exercise could begin, villains show up, causing Shota to command Thirteen to protect the students.

Thirteen begins to lead the evacuation of the U.A. students, but Kurogiri stops them. When Eijiro and Katsuki try to attack Kurogiri, Thirteen tells them to stop and run away instead. Thirteen then tells Tenya to dash back to U.A. to inform the school of their troubled situation. After Tenya shows reluctance to do so (not wanting to abandon his classmates), Thirteen encourages him to use his Quirk to save them.

Thirteen fights Kurogiri, using their Black Hole Quirk to suck in the amorphous villain. However, Kurogiri is able to counter with his own Warp Gate Quirk, causing Thirteen's Quirk to backfire on themself. Kurogiri notes that, despite their powerful Quirk, Thirteen is inexperienced in combat, which led to their demise. Thirteen ends up having half of their suit disintegrated, being incapacitated to keep fighting.

After All Might defeats Nomu and the Heroes which Tenya called arrived, Thirteen is shown to still be alive (their arms and back injured) and uses their Quirk to suck Kurogiri and Shigaraki into a Black Hole, seemingly turning them to dust and ending the League of Villains's attack on the U.S.J.

U.A. Sports Festival Arc
Thirteen is seen watching the Sports Festival along with All Might. As the battle between Izuku and Shoto begins, Thirteen asks All Might if Izuku and Shoto are the ones that jumped in to save him before, to which All Might replies that they are.

End of Term Test Arc
On the day of Class 1-A's test exercise, Thirteen is one of the teachers that Class 1-A will face in their end of term test exercise. Thirteen will face Ochaco and Yuga in their test exercise.

Ochaco, Yuga and Thirteen arrive in an uninhabited city where Class 1-A's test exercise will take place. In the city, Thirteen explains the 30-minute test; Ochaco and Yuga must either handcuff them or one of them must escape the battlefield within 30 minutes in order to win and pass the test. The test begins.

Ochaco and Yuga reach the escape gate but before they can go through it, Thirteen creates a Black Hole, causing the duo to hold onto a guardrail to prevent themselves from 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 away the lasers. After Yuga asks an embarrassing question, Ochaco lets go of the guardrail and as a result, Ochaco gets drawn towards Thirteen. Facing Thirteen directly, Ochaco uses her combat skills learned from Gunhead and manages to handcuff Thirteen, allowing her and Yuga to pass the practical test.

Quirk and Abilities
Black Hole (ブラックホール Burakku Hōru): Thirteen's Quirk creates a vortex that turns anything it sucks in into dust. Thirteen uses their Black Hole through the use of a gadget on their right hand.
