History
In a meeting with other Pro Heroes to discuss the unwilling civilians injected with Trigger and a member of the police force. The member police officer explains that the people in question were more of victims than villains. Endeavor argues 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, has his reply to the problem delivered by Naomasa Tsukauchi. He states that he would assess the situation at the scene more carefully because as heroes, they must not bring harm to innocent citizens.

Entrance Exam Arc
Death Arms guides civilians out of the area while other heroes are fighting a villain.

Later on, he is among the heroes who are trying to stop the mud villain who is controlling Katsuki Bakugo; but Desutegoro cannot do anything since the villain is too fluid. None of the heroes who are present can do something against the villain and Desutegoro clenches his fist in anger. As Desutegoro and the other heroes wait for a hero who is able to hurt the villain, Izuku Midoriya tries to help Katsuki. Desutegoro tries to stop him but Izuku does not listen to him. All of the Heroes then try to help him, but before they can do anything, All Might defeats the villain with one attack. Desutegoro and the other heroes then clean the area. He later scolds Izuku for his actions since he could have been killed.

U.A. Sports Festival Arc
Having been assigned as security, Death Arms, Kamui Woods, and Mt. Lady are seen outside U.A. High School's Sports Festival Stadium. Shinrin Kamui and Desutegoro originally wanted to scout for talented individuals but they are not able to do that because of the guard duty.

During the obstacle course of the festival, Death Arms spots Izuku Midoriya, the young man who purposely got himself involved with a villain and was amazed by his progress.

Later, after the rules of the Cavalry Battle have been explained, Death Arms, Kamui Woods, and Mt. Lady are in the break room and start discussing the U.A. Sports Festival. Death Arms says that the Sports Festival is all about preparing the young heroes for the real world of heroes and that the Obstacle Race was a way of showing that you need to kick down others to show what you are able to do. Mt. Lady, after mentioning that she feels bad about having done that to Kamui Woods, mentions that Heroes need to work together in order to accomplish a goal and the Cavalry Battle is a good representation of that.

Quirk
Death Arms' Quirk is described to be a straight-forward Strength Enhancement Quirk, that gives Death Arms a level of superhuman strength. This Quirk has not been shown to need to be activated, though he has been seen to bump his fists together before using his strength. Death Arms is capable of holding large objects that are heavy and made of metal, such as telegraph poles.

Death Arms' Quirk allows him to carry things that are far beyond the normal human limits. However, his Quirk has not been displayed to provide him with incredible speed, like One For All does, being focused in his arms along (hence his hero name). Nor has he been shown to be able to jump long distances, or have particularly high reflexes. Despite this, it can be assumed that his Quirk is very useful against most villains in close-combat.

However, this Quirk is shown to be totally ineffective against the Sludge Villain. It is also shown to not even come close to the power that One For All has.

Trivia
