The Overseer

"'I've never been sick, I've never been injured...what do I do now?'- David Dunn"David Dunn is the overall main protagonist of the Eastrail 177 film trilogy, serving as the main protagonist of the 2000 film Unbreakable, a cameo character in Split and the main protagonist of Glass.

He was once an ordinary man who wanted a normal life with his wife and son but that all changed after he was involved in a horrific train crash, resulting in him being the sole survivor. After persistent badgering from Elijah Price, he learns that he has super-powers. At first, he was very reluctant to even accept he had superhuman abilities. David eventually comes to terms with it starts to use his abilities for good.

Years later, he took up the name of a superhero called The Overseer and his actions were reported more frequently in the news before he was sent to Raven Hill Memorial after a brief standoff with Kevin Wendell Crumb, a man with DID and a malevolent personality called "The Beast".

Early Life
When David was a young child, he nearly drowned in a swimming pool. This left him traumatized as well as a weakness and fear of water.

In college, David was dating his future wife Audrey. He seemed to have everything as he was also a star athlete for his school's football team. Unfortunately, this all came to an end. David and Audrey ended up in a near fatal car accident, well near fatal for Audrey. Due to David's powers, he was left unharmed. He ended up saving Audrey's life using his superhuman strength to rip a door off a car and pull her out of the wreckage. David blamed the accident for why he stopped playing football. After a horrific train crash, David Dunn wakes up in the hospital being the only survivor.

Events in Split
Shortly after the events of Split, David watches the news report on The Horde in a diner. The name "The Horde" reminded a lady sitting next to David of a speculation of a wheelchair bound terrorist who was incarcerated 15 years prior and asks what his name was. David replies "Mr. Glass", before taking a sip of his coffee.

Events in Glass
Three weeks after the Horde's manifestation, Dunn is seen working along with his son, Joseph in fighting crime. One day, he learns from Joseph that Crumb has held a group a group of cheerleaders hostage in a warehouse. He arrives at the nick of time to save them but is confronted by the Horde personality, and the fight turns onto the streets. They are eventually stopped by the PPD and sent to a mental institution where Elijah Price is held.

Dunn, along with Price and Crumb, is examined by Dr. Ellie Staple, the head doctor of the institution. She believes that there are no such thing as having superpowers and thus concludes that they have a mental illness. However, after Price and Crumb then work together to unleash the Horde's personality to the world so that they are aware of superpower existence, Dunn breaks out of the institution and confronts Crumb in a fight.

Soon after, Staple arrives with armed troopers and explains that she has spent the majority of her career preventing superheroes from exposing themselves to the world and it turns out both Ellie and the armed men are part of a secret anti-superhuman society. The men capture David and kill him by drowning, while Kevin kills Price and is shot to death by the troops thereafter.

Legacy
Unbeknownst to Staple, the security cameras were hacked by Price prior to his death, and the footage is sent to a private site, allowing Casey, Joseph, and Mrs. Price to expose the existence of those with superhuman abilities. Afterwards, Staple is shocked and furious that the public is now aware of superhuman abilities, which she fought to hide, and her plans and that of the secret society are destroyed. At a train station, Joseph, Casey, and Mrs. Price grieve over the deaths of their respective loved ones and join hands as a family while the footage from Raven Hill goes live.

Personality
David Dunn was once an ordinary man and wanted to keep it that way. He, at first, was not interested in the ideas of superheroes existing. In fact, he downright refused to believe he could have such incredible powers. Despite not wanting to be a superhero he takes on roles that involve protection. At a stadium, he worked as a security guard. When he begins to train his powers, he makes sure his son, Joseph, stands back so he doesn't get hurt.

He doesn't let emotions cloud his sense of wrong or right. When he finds out that Elijah Price (now calling himself Mr. Glass) orchestrated the train crash and other terrorist incidents, he alerts the authorities. Despite this, he was clearly traumatized by the idea of his mentor being the villain all along.

Powers and Abilities

 * Invulnerability: David Dunn's main power is the ability to withstand incredible physical abuse leaving him with no markings at all. It was first revealed to him at the beginning of the film when he was able to be the sole survivor of a train crash without a single scratch on him.
 * Superhuman Strength: Along with an unbreakable body, David also possesses super strength. He is shown to be able to bench press around 350 pounds. In a deleted scene he is shown to be able to press 490 pounds. The true limit of his strength is yet unknown.
 * Enhanced leap: The strength in David's legs may allow him to leap/jump further and higher than a average person.
 * Enhanced Speed: The strength in David's legs may allow him to run faster than a average person due to his Career as a Star college Football Player.


 * Superhuman Stamina: Before the car crash, David was a star college football player. This was likely due to his superhuman stamina.

 * Extrasensory Perception: By touching or focusing on someone, David is able to see if someone has done something wrong and what it is. He is also able to sense it.

Weaknesses

 * Water: Elijah Price explains to David that all superheroes have a weakness, just like how Superman's weakness is Kryptonite. David's weakness is water after he almost drowned as a child. The traumatic event does not only bring him anxiety whenever he is submerged in water but he also never learned how to swim or properly float.
 * Other Superhumans: While David Dunn is stronger than normal humans, it can be proven a challenge when fighting other superhumans. When going up against the Horde, they were shown to be equally matched in strength.

 * Joseph Dunn - Son

Enemies

 * Elijah Price/Mr. Glass - Former ally turned enemy

Trivia:

 * David's weakness to water could be interpreted as his unbreakable body might weigh so much that he cannot float in water as a result.
