Lyla Michaels, known under the code name Harbinger, is a high-ranking member of A.R.G.U.S. Lyla is the fiance of John Diggle, who she affectionaly called "Johnny" during his time in Afghanistan, they have since rekindled their relationship and had their first child, a daughter, Sara Diggle in the season 3 premiere.
Lyla and John met in Afghanistan, where both were serving as soldiers, and then got married. At the end of John's second tour, they rotated back Stateside where their marriage couldn't adapt to a civilian life and they divorced. John went back to Afghanistan for a third tour, while Lyla entered ARGUS.
In "Unfinished Business", John met with Lyla rather than helping Oliver, and gave her information on Deadshot. She was shocked, as they weren't even able to find his name, and he just explained that it was for something he was working on, a lie which she could easily see through.
In "Home Invasion", when John visited the main A.R.G.U.S. building, Lyla spotted him. She scolded him for trying to use her to hunt down Deadshot, and told him to do otherwise. Sometime later, Lyla was to meet with Floyd Lawton and bring him in. However, Floyd did not show and tried to snipe her from a distance. Lyla was saved by John, who attempted to follow Floyd but was knocked unconscious.
In "Crucible", she meets with John and flirts with him when she discovers he is single again. She gives him information about military-grade weapons being stolen. She then reveals that she is single as well to him. They part ways soon after.
In "Keep Your Enemies Closer", In the episode, Lyla is missing in Russia, having been captured during an intel operation in a Russian gulag. John is recruited to break her out, because A.R.G.U.S. does not have sufficient resources for the op, and the political masters already consider her disavowed and dead to them. John arranges to get arrested and sent to the prison, where he finds Deadshot, whom he teams with to break Lyla out of jail. Returning to the United States, John and Lyla rekindle their relationship.
In "Suicide Squad", Lyla and John are enjoying a romantic interlude when they are sent on a mission by A.R.G.U.S. to lead the Suicide Squad in capturing and destroying a nerve gas in the possession of Gholem Qadir. During the mission, Amanda Waller kills Shrapnel when he tries to flee. This causes a rift between Lyla, who accepts Waller's methods, and John, who objects to their brutality.
Later Lyla poses as John's bodyguard to infiltrate Qadir's party. She removes a tracking device from Deadshot in order to evade an A.R.G.U.S. drone, and she and John reconcile their differences.
In a flashback sequence, Lyla is shown serving as a soldier in Afghanistan. She captures Gholem Qadir and is seen meeting John for the first time.
In Unthinkable, Lyla freed the Suicide Squad to stop Amanda Waller from destroying Starling City. During this coup, Amanda revealed that Lyla is pregnant with John's child but kept it a secret from him.
In "The Calm",
- In "Corto Maltese",
In "Draw Back Your Bow",
Lyla was tracked down by Captain Boomerang. Boomerang attempted to kill Lyla for her failed attempt of detonating his bomb located in his neck during his time in Task Force X. Lyla is hit by a boomerang and The Flash took her to the hospital where John Diggle proposed.
Lyla is kind, caring, intelligent and calculating, and has good morals, she is more loyal to her principles and the people she cares about, than A.R.G.U.S.; if Amanda Waller had not called off the drone strike planned to bomb Starling City, Lyla most definitely would have gone through with killing her.
Even though Lyla has no known special abilities beyond that of a basic human being, her skills are apparently so great, even Amanda Waller with her tendency to treat her agents like expendable pawns, found Lyla very difficult to replace. Waller even went as far as to threaten Oliver Queen and John Diggle to rescue Lyla when her superiors wouldn't allow her to out of fear of causing an international incident.
Arrow: Season 2.5Edit
- Lyla used the codename "Harbinger" during an A.R.G.U.S. operation to capture Floyd Lawton. In the DC comics multiverse, Lyla operated as a superhero under this name and was a central figure of the massive DC Comic book event known as "Crisis on Infinite Earths".
