- "Tell me. Where can I find Damien Darhk?."
- —Lonnie Machin to H.I.V.E. soldier after subduing him[src]
Lonnie Machin, nicknamed Anarky by Felicity Smoak, is the foster son of the late Crystal Olguin and the late Michael Olguin and a former part-time mob enforcer who was originally hired by H.I.V.E. to stop Jessica Danforth from running for mayor. However, after his disfigurement, he became an anarchist with the intentions of destroying both H.I.V.E. and Green Arrow; but he ultimately fails.
Lonnie worked for Rick Pinzolo, the Bertinelli crime family and the Chinese Triad; eventually Rick and many other criminal organizations fired him because they realized that Lonnie was not only too unstable and extreme, but he also lacks a moral compass and a sense of honor.
Stint with H.I.V.E.
Lonnie began working for H.I.V.E., where he made an attempt to stop Jessica Danforth from running for mayor. After Lonnie's set up attack, he escorted Jessica out. When a security guard noticed he wasn't in Danforth's detail, Lonnie attacked the guard with his electric baton. Before he could go after Danforth, Oliver threw him off a balcony. Lonnie was chased by Oliver through the building and over rooftops but managed to escape, though he left his fingerprints behind on a windshield.
Later, he was told by Damien Darhk all he did was for nothing and that he wasn't worthy of joining H.I.V.E.. Lonnie asked for a second chance and Damien told him he has one last chance, as his organization doesn't believe in third chances.
Lonnie later kidnapped Madison Danforth in an attempt to make Jessica Danforth drop out. Damien met with Lonnie once more demanding to know the whereabouts of Madison. Although Lonnie was quite pleased with his efforts, Damien was visibly shocked at Machin's 'sloppy' and extreme tactics, declaring that Machin had crossed a line. Damien scolded Machin, citing his (Damien's) preferences and respect for order, precision and discipline and telling Machin that all he (Machin) represented was anarchy. Darhk subsequently terminated his and HIVE's relationship with Machin and, before leaving, ordered Lonnie to once more clean up his mess. 
After he was rejected by Damien, Lonnie pretended to free Madison but broke her pinky, telling her he changed his mind. Shortly after, Team Arrow arrived. Lonnie used a flamethrower as a distraction and slipped away. After Green Arrow and Speedy went after him, Lonnie shocked Speedy with his baton. He battled Green Arrow and eventually overpowered him. He was then attacked by Speedy, who knocked him into chemicals as Speedy used the baton, setting Lonnie on fire, though he was extinguished by Green Arrow. While being transported to Starling General Hospital, Lonnie escaped and killed 2 paramedics, before leaving an anarchist symbol behind.
Hunting down Damien Darhk
Several months later Lonnie killed his foster parents. Now wearing a mask he went after Damien Darhk as revenge for his betrayal. He managed to find the lair of H.I.V.E. and killed all the guards present. However Darhk had anticipated his arrival and had fled. Lonnie stayed at his former home and placed a boobytrap as he expected a counterstrike from H.I.V.E. Instead Team Arrow showed up. He expressed joy to see them and then run off while planted rifles forced them to take cover. Thea chased him and he knocked her over with an explosive. He mentioned to Thea that he would not hurt her as she had helped him get to his true self. As Thea aimed her bow he asked her to kill him. The Canary interrupted and Lonnie attacked her. However he got surprised and knocked out by Oliver and Diggle.
Tied up to a pole he got questioned by the Green Arrow. Lonnie refused to answer any questions and told him there was nothing he could do to him that he had not enjoyed already. Thea told Oliver he had to leave. Lonnie talked to Thea and told her she had burned away his weaknesses and now he had transcended to something better. He teased her that he knew she wanted to kill him and that she could not control herself. He mentioned he noticed the hunger to inflict death in her eyes. She was about to impale an arrow to his throat but then the cops showed up and she was forced to flee.
As the cops drove him away The Green Arrow showed up and broke him free. Lonnie told him he would not tell him where Darhk was. The Green Arrow set him free and told him he had to kill Darhk.
Lonnie was able to quickly track down the house where the family of Darhk was living. He painted his anarchy symbols all over the place and took his wife and daughter hostage. Calling Darhk to come he then prepared to torture them both while waiting. Team Arrow bursted in and freed the family. Lonnie was surprised that they were trying to stop him again. He engaged Thea and Oliver in a fight and quickly subdued them before running off. Thea chased him and tied him to a tree with a trick arrow. Thea prepared to kill him however she stopped at the last moment. Disappointed that she would not kill him he broke free from his bonds. He quickly defeated her and then seemed to pause for a moment before he ran off.
Rampage in Tevat Noah
Lonnie was able to find the underground H.I.V.E. facility Tevat Noah and infiltrated the place. He killed multiple guards and questioned some to learn more about the facility and where Damien Darhk is. Machin then took control of a house which controlled the CO2 scrubbers of the facility and threatened to stop the life support system. Machin mocked some captured guards about living underground like parasites and then prepared to shut down the life support system. Thea Queen showed up and told him to stop. Machin told her to leave but she identified herself as the one who burned him. Thea tried to talk him down but as Machin did not responded Malcolm Merlyn hit him in the shoulder with an arrow. Machin fired his gun at Malcolm and then escaped the scene.
Machin tracked down Alex Davis and knocked him unconscious. As Thea found him he told her he was not pleased that she stopped his plan to take vengeance on Darhk. As he now had to wait for Darhk he had time to kill. He told Thea her problem was that she was at the mercy of some guy. He told her she was able to make her own decisions and that she was not a pawn but a queen. Thea attacked him and the two engaged in a fierce fight. As Alex got back to his senses Machin quickly knocked Thea down and told her he would liberate her from this guy clouding her mind. As Thea screamed for Alex to run Machin gave him an electric shock with his baton and killed him. Enraged Thea attacked him and was able to knock him out.
As Malcolm Merlyn showed up with multiple soldiers Machin quickly vanished from the scene. Wandering around the facility he infiltrated the building where Ruvé Adams was and eavesdropped on her as she scolded Malcolm Merlyn for his inability to take down Machin. He then managed to kidnap her and her daughter Nora and took them hostage in the power supply. He tempered with the engineering which made the energy supply highly unstable. Using a video he called out Damien to pay for his betrayal. If Damien would not show up he would kill his wife or daughter in 20 minutes and blow the entire facility up in 21 minutes.
He told Ruvé this was quite like before as she and her daughter where the bait again and he was again trying to kill her husband. As Ruvé told him Tevat Noah was the last safe place on earth and he was about to destroy it he mentioned that he was not a rational guy. Machin got shot in his leg with an arrow by Oliver Queen as he John Diggle and Thea Queen came in and demanded him to let Ruvé and her daughter go. He told them that shooting him would be unwise as the place was highly unstable and could explode with a missed shot. As Oliver told him he would not escape he tried to stab Ruvé with the arrow from his leg but got stopped by Oliver who shot him in the shoulder with an arrow. However a missed shot from Thea made the place go unstable and Machin quickly yanked the arrow from his shoulder and stabbed Ruvé in her heart. As the place started to blow Machin fought Diggle, Oliver and Thea simultaneously and was able to knock them down. He then said goodbye to Thea and fled the scene.
Against Star City
Using a bomb, Machin planned to destroy at least half of Star City in the explosion. However he was confronted by the Green Arrow. Seeing the vigilante, Machin used a pair of Kamas to engage Green Arrow. After a brutal fight, the Green Arrow was finally able to impale Machin's hand with an arrow against the wall. Machin expressed disappointment that Green Arrow would not kill him, after which the emerald archer knocked him out, leaving Lonnie for the SCPD to arrest.
Lonnie is a sadistic murderer and a psychopath, taking deep pleasure in making his victims suffer, as he was planning to torture Madison Danforth for hours. He killed cops and paramedics even while horribly injured himself. He enjoys playing mind games with his victims, feigning mercy before resuming his torture. He believes that the natural order of things is chaos, reveling in the randomness of things. Lonnie is shown to be confident and ambitious. He was barely fazed when Team Arrow burst in.
As an enforcer, he had worked for different factions but was assumed by many to be too unstable and extreme; because of this, he has been fired by many criminal organizations. When Damien Darhk rejected him he nearly crossed the line against him by grabbing his arm while protesting.
Lonnie has no guilt or remorse for killing innocent people, and does nothing to try to avoid it; he has no sense of honor or morals. He mentioned things find their way through the chaos and are not guided by rules, this philosophy of anarchy seems to be his code as he himself does not obey to any laws or even logic.
After he was burned he somehow considered himself to be more complete and mentioned his weaknesses were gone. During this period he also started painting anarchy symbols when committing crimes. He became totally obsessed with Thea and considered her burning him a baptism by fire. When he met Thea again he recognized pieces of himself in her and wanted her to kill him. He seemed highly disappointed and angry that Thea did not wanted to kill him. He has developed a weird sort of affection for Thea, calling her "mommy" for "creating him" by burning his body. He's been shown to care for her in his own strange way, commenting on his "mommy's" strength and good looks, as well as trying to "liberate her" from influence of other men on her life by killing Alex Davis.
After Damien sold him out, Lonnie became focused on taking him out. Obsessed with having revenge on Damien he even wanted to destroy Tevat Noah and kill hundreds of innocents in the process just to hurt Damien. He went after Damien's wife and daughter again and was even willing to die himself to cause damage to Damien, planning to blow up Tevat; killing Ruvé Adams Damien's wife, himself, hundreds of citizens and H.I.V.E. operatives in the process. He is completely aware that his rage has overwhelmed his judgement; when Ruvé told him that destroying Tevat Noah would doom humanity, he only responded “Did I leave you with the impression that I was a rational guy?”.
