My Hero Academia: World Heroes' Mission (2021)

A cult of villains known as Humarise believes that Quirks will eventually become so powerful that they will bring about the extinction of humanity. Because of this, they have planted bombs all over the world filled with "Trigger" gas which kills Quirk users by driving their Quirks out of control. Their leader, Flect Turn, plans to use these bombs to save humanity by killing the Quirk population. After Humarise detonates its first Trigger Bomb, the World Heroes Association dispatches Pro Heroes and U.A. High Hero Course students to Humarise's targets in hopes of disarming the remaining bombs. Izuku Midoriya, Katsuki Bakugo, and Shoto Todoroki are among those sent to the country of Otheon, the supposed main headquarters. None of the Heroes find any trace of Humarise and they are put on standby.
During an outing, Midoriya, Bakugo, and Todoroki encounter a jewel robbery in progress. Todoroki and Bakugo pursue the Villains while Midoriya gives chase to the Villains' courier, Rody Soul, a street urchin who took the job to provide for his younger siblings. Meanwhile, Allan Kay, a Humarise scientist, flees with an important briefcase but is attacked by a Humarise agent, Beros, leading to a car crash near Midoriya and Rody's chase. Rody accidentally grabs Kay's briefcase, and nearly gives Midoriya the slip, but he catches up. They are soon attacked by the police, but Midoriya escapes with Rody using Blackwhip.
Midoriya is publicly accused of mass murder and goes off the grid per Todoroki's advice. Midoriya and Rody make their way to the neighboring country of Klayd as the Otheon police won't have jurisdiction there. Midoriya sends a coded message about his new destination to Todoroki, who heads off with Bakugo to join him there. That night, Rody becomes homesick and secretly reports the briefcase to the police. The officers that arrive turn out to be Humarise agents, who attack him. Midoriya, having been woken up by Rody's bird companion, Pino, saves him, but is wounded by Beros during the fight. Rody apologizes to Midoriya while patching him up, explaining that his father abandoned the family to join Humarise, and that he and his siblings were ostracized as a result.
The two are attacked at the Klayd border by Beros, but are saved by Bakugo and Todoroki. Beros jumps to her death to evade capture. In the aftermath, Midoriya discovers a hidden compartment in the briefcase containing a puzzle which Rody played with as a kid. Rody solves it and finds a USB device and a data disk inside. The disk contains a message from Kay, who reveals that he and Eddy Soul, Rody's father, were forced by Humarise to create the Trigger bombs. The device contains a kill code for the bombs created by Kay and Eddy. Humarise announces that they will detonate their remaining bombs in two hours, forcing the deployed Heroes to work through the ensuing global panic to find them.
Midoriya and the others head to Humarise's home base with the device on a plane piloted by Rody. Bakugo and Todoroki deal with high-ranking Humarise goons, while Midoriya faces Flect Turn, whose Quirk reflects whatever comes into contact with him. Midoriya is overwhelmed by Flect Turn's natural defenses, as well as his laser barrage. Rody arrives and seemingly betrays Midoriya by handing over the device in exchange for his siblings' safety. However, thanks to Pino, whom Rody had revealed to him earlier is actually his Quirk, which expresses his true feelings and intentions, Midoriya realizes it's a feint and catches Flect Turn off guard. Realizing that Flect Turn's Quirk has a limit to how much damage it can take, Midoriya pushes himself to One for All 100%, and defeats Flect Turn with a barrage of punches. Meanwhile, Rody heads for the Trigger Bombs' control system, and despite being wounded by the laser defense system, he and Pino barely manage to insert the device in time.
In the aftermath, Humarise's surviving members are arrested, while the Heroes are healed at the hospital. As Midoriya heads back to Japan, he and Rody bid a tearful goodbye to each other. Class 1-A reunites back at U.A., while Rody gets a job as a bartender and pursues his dream as a pilot.
