In *Avengers: Endgame* (2019), several major characters meet their ends through sacrifice, execution, or the power of the Infinity Stones. Below are the specific details of who dies and how they meet their end:
### 1. Thanos (Original Version)
* **How he dies:** Decapitation.
* **Specific Details:** Early in the film, the surviving Avengers track Thanos to a remote planet called "The Garden." After discovering that Thanos has used the Infinity Stones to destroy the stones themselves—making it seemingly impossible to undo "The Snap"—an enraged **Thor** uses his axe, Stormbreaker, to decapitate Thanos. This version of Thanos dies roughly 20 minutes into the film.
### 2. Natasha Romanoff (Black Widow)
* **How she dies:** Sacrifice / Falling.
* **Specific Details:** During the "Time Heist," Natasha and Clint Barton (Hawkeye) travel to Vormir in 2014 to retrieve the Soul Stone. They learn from the Red Skull that the stone requires the sacrifice of someone the seeker loves ("a soul for a soul"). After a physical struggle where both attempt to sacrifice themselves to save the other, Natasha ultimately throws herself off the cliff. Her death is permanent and cannot be undone by the Infinity Stones because it was a ritual sacrifice.
### 3. Nebula (2014 Version)
* **How she dies:** Shot by her future self.
* **Specific Details:** The 2014 version of Nebula (who is still loyal to Thanos) travels to the present (2023) to facilitate Thanos’s invasion of Earth. During the final battle, she is confronted by the "Good" present-day Nebula and the 2014 version of Gamora. When the 2014 Nebula refuses to change her ways and attempts to kill Gamora, the **present-day Nebula** shoots and kills her past self.
### 4. Tony Stark (Iron Man)
* **How he dies:** Successive exposure to Infinity Stone energy.
* **Specific Details:** In the climax of the final battle, Tony Stark manages to steal the Infinity Stones from Thanos's gauntlet and transfers them to his own Mark 85 armor. He utters the iconic line, "I am Iron Man," and snaps his fingers to turn 2014 Thanos and his entire army into dust. Because Stark is a mortal human, the sheer power and gamma radiation released by the six stones are too much for his body to handle. He dies shortly after the snap from catastrophic internal injuries and radiation burns, surrounded by Pepper Potts, Peter Parker, and James Rhodes.
### 5. 2014 Thanos and His Army
* **How they die:** Disintegration (Dusted).
* **Specific Details:** The version of Thanos who traveled from 2014 to the present, along with his entire military force—including the **Black Order** (Ebony Maw, Corvus Glaive, Proxima Midnight, and Cull Obsidian), the Outriders, and the Chitauri—are erased from existence when **Tony Stark** snaps his fingers. Like the victims of the original "Snap" in *Infinity War*, they crumble into ash.
### Note on Other Characters
While many characters were "dead" at the start of the film due to the events of *Infinity War* (such as Peter Parker, T'Challa, and Wanda Maximoff), they are resurrected by **Bruce Banner (Hulk)** using the Nano Gauntlet midway through the movie. Characters who died **before** the original snap in *Infinity War*—such as the original **Vision**, **Heimdall**, and the original **Loki**—remain dead throughout the events of *Endgame*.
