Miguel Robles is a corrupt former agent of Crows Security, the former head of the Crows Homicide Division, and a former officer of the Gotham City Police Department. He briefly took on the alias of the Detonator, which belonged to a known terrorist bomber that had died seven years prior, to try and cover up his murder of Lucius Fox.
GCPD and investigating the Detonator
Joining the Crows and killing Lucius Fox
In 2015, Robles was hired as an agent of Crows Security and put on Tommy Elliot's personal detail. At some point, Tommy paid him $10,000 to rough up Lucius Fox for a journal the latter wrote. Robles cornered Lucius in Sip&Dash and threatened him for the journal at gunpoint, but Lucius refused. Robles then warned that if Lucius didn't give up the journal to Tommy, he would go after his son, Luke Fox. This enraged Lucius so much that he charged at Robles, who reacted by shooting him in the chest.
Robles then killed a clerk who witnessed the crime and framed Reggie Harris, a small-time criminal who happened to be at Sip&Dash, for the murders by knocking him out, planting the gun on him, and drenching him in Lucius' blood. The store's owner, Alia Nazari, was bribed $51,000, covered as compensation for damages, to let Robles and a team of Crows agents steal and destroy the security footage from all of Sip&Dash's cameras.
Discovering Sophie's secret
In 2020, Robles watched a video manifesto Mouse sent to the Crows revealing that he had kidnapped the mayor and police commissioner's children. Mouse demanded Alice's release in exchange for the two boys.
Robles was on the Crows team hunting Nocturna and took a copy of the video footage from Curse, where she killed her latest victim. Robles learned from the footage that Sophie had freed Batwoman from Nocturna and let her escape. He decided to turn over the evidence to Commander Jacob Kane, stating that it was the right thing to do. Being the only one who knew about it, Robles told his superior that it was his choice whether he wanted to view the footage or destroy it.
Attempted coverup and arrest
A few days later, Robles was called into Jacob's office and questioned about the oddities in Reggie's case. Robles replied that the only thing he found strange in the case was that Lucius was a hero and the people were trying to free his killer.
Later that evening, Jacob approached Robles again, asking why he sent $51,000 to Sip&Dash' owner, Alia, after arresting Reggie. Robles claimed it was a refund for having destroyed the convenience store when arresting him. Jacob wondered if it was really for destroying evidence, to which Robles insisted that a Crow would never have done something like that.
A week later, after "Fisher's death, Robles took on the mantle of the Detonator to destroy any evidence that could link him to the assassin. He started by targeting various individuals deemed to the public as heroes to follow the previous Detonator modus operandi, while pursuing his own agenda; after Officer Wilcox chose to deactivate the bomb attached to him by detonating a second one, the old site of Gotham City Bank, which contained the account where Robles transferred money to "Fisher, was destroyed. Later after targeting Bobby Reeves, "Fisher"'s house was destroyed on Maple Street.
Robles then kidnapped Jacob, tying him to a chair in his office and attaching a bomb on him, which would deactivate if Jacob detonated another under Wayne Tower. Afterwards, Robles tried to leave the city but was ambushed by Batwoman on Rucka Avenue and brought to Wayne Tower. She demanded him to disarm the bomb, to which Robles explained he couldn't unless the other bomb detonates.
Luke then pointed a gun at Robles, demanding to know why he killed his father. Robles revealed he was acting on Tommy's orders to get Lucius' journal, but was only meant to interrogate him. Robles insisted that Lucius' murder was an accident, since the man attacked him when he threatened Luke. Luke was determined to kill Robles to avenge his father but Batwoman talked him out of it. The two knocked Robles out and the bomb was detonated securely inside a blinded room in Wayne Tower.
Robles was arrested and sent to Blackgate Penitentiary. He eventually gave up the names of the other people involved in the orchestration and cover-up of Lucius' murder in a bid to avoid the death penalty. This led the Crows and Bat Team to investigate Tommy and retrieve Lucius' journal.
Robles came off as an honorable and heroic individual, firmly loyal to the Crows and devoted to protecting Gotham. His sense of justice and deference to the law prompted him to report to Commander Jacob Kane that Sophie Moore was secretly working with Batwoman, believing this to be a betrayal of what the Crows stood for. Robles believed this was the right thing to do but left it up to to Jacob decide what he wanted to do next. He was among those who regarded Lucius Fox as a "hero" in Gotham and stated to be disgusted at the idea that his killer might be freed.
However, this was ultimately nothing more than a façade. In truth, Robles is a selfish, greedy, dishonorable and corrupt individual who would do anything for money. On the orders of Tommy Elliot, he tried to extort Lucius for a journal he wrote and after Lucius' murder, he was willing to kill an innocent civilian who was a witness and frame Reggie Harris. Robles went to great lengths to cover up the truth for the following five years, such as hiring a hitman and later posing as a terrorist to destroy many buildings and erase any evidence connecting him to his past crimes, not caring how many innocent people would be hurt or killed.
Robles is extremely arrogant and egotistical to the point of being delusional, as he believes that his status as a Crows made him untouchable, legally it doesn't, he also called Batwoman "trash" out of a sense of superiority. Underneath his arrogance, Robles proved to be quite cowardly, as he tried pleading for his life when cornered by Lucius' son, Luke Fox, and gave up the names of all of his accomplices in order to avoid the death penalty.
