Tommy Merlyn is introduced as part of DC's New 52 reboot in 2012 as the son of Merlyn. Tommy is best friends with billionaire playboy Oliver Queen. When Oliver's father had relegated him to clerical work on an oil rig on the Pacific Ocean, he turned the rig into a hub for wild parties. At one such party, Oliver had decided to demonstrate archery to Leena and Tommy. The group of friends were awaiting on a rock star hired by Oliver to play for them. Things got much worse when the helicopter meant to be carrying this rock star turned out to have been commandeered by oil-thieving terrorists. Tommy dragged Ollie to safety, leaving Leena outside on the platform. The two of them discovered a wounded crewman who blamed Oliver for the security breech, as the terrorists commandeered one of the helicopters that was not even supposed to have been there. These terrorists had fixed the platform and several of its occupants including Leena with explosives, holding them hostage until they could siphon millions of dollars worth of crude oil. Tommy and Oliver managed to get past some sentries, and despite his warnings, Oliver went up onto the platform alone, armed with only a longbow, in the hopes of saving Leena. Oliver had a plan: to take just one shot, through the terrorist leader's wrist, causing him to drop the detonator into the ocean. Unfortunately, on its way down, the detonator bounced against one of the platform's struts, and activated. Leena and everyone around her were obliterated by the explosion. Before Oliver could be caught in the explosion, Tommy leapt out, and thrust them both into the safety of the ocean. Badly burnt, Tommy warned that these would not be the only people that Oliver's recklessness would get killed, before passing out. One year later, a monastery on a pacific island has been caring for a badly burnt coma patient for years. Suddenly, Tommy wakes up. He is next seen in the 2014 Green Arrow storyline "Kingdom", in which he appears as the heavily burned "Dark Archer". Killing Mack Morgan before he could give critical intelligence to destroy the reputation of his employer, John King. King, a billionaire hired Merlyn with bringing Mia Dearden to him. Thanks to John Diggle's skillful driving, Oliver manages to catch up to Merlyn on top of a monorail train, where he learns that Tommy is nearly a match for him with a bow. When Tommy attempts to attack him at close range, though, he recognizes his opponent as his old friend just as they pass under a tunnel. When Oliver recovers from the quick duck, Tommy is gone. Fortunately, he left Mia behind.

Tommy Merlyn makes his live-action debut in the television series Arrow, portrayed by Colin Donnell, while the character's child depiction portrayed by Arien Boey in season three. A starring character in season one, he's the childhood best friend of Oliver Queen and the son of Malcolm Merlyn / Dark Archer. A spoiled playboy who lives off Malcolm's financial support, Tommy is in love with Laurel Lance and the pair date. When Malcolm cuts him off financially, Tommy starts the Verdant nightclub along with Oliver. Their friendship gets strained when Tommy learns that Oliver is a vigilante, seeing his friend as a killer. Tommy later breaks up with Laurel, as he fears Laurel is still in love with Oliver. During his father's Undertaking, Tommy rescues Laurel from a collapsing building and dies after making amends with Oliver. Subsequent seasons have Tommy occasionally seen in hallucinations or flashbacks, as well as also revealed to be Thea Queen's paternal half-brother in season two and a posthumous impersonation dressed as Green Arrow in season six. In the series finale, Tommy is alive with Earth-Prime's existence as its Laurel's widower and meets Earth-2 Laurel as well. Encountering his wife's doppelganger, even though is strange for Tommy, but he said that "there's something nice about it, too;" meeting Earth-2 Laurel provides Tommy the closure he needed from his wife's death. Tommy also attended Oliver's funeral.
Donnell then portrays his Earth-X doppelganger during the 2017 Arrowverse crossover Crisis on Earth-X as "Prometheus". A partner and friend of the Führer and an enforcer of Earth-X's New Reichmen of Earth-X, he assists in the Earth-1 invasion but is defeated by Sara Lance and Alex Danvers, and interrogated for his group's motives while offered redemption but cruelly taunts this notion and takes a suicide pill out of spite towards the Earth-1 superheroes.
Donnell next portrays his Earth-2 doppelganger in the final season's premiere as the Dark Archer. Upset over his half-sister's death from a Vertigo overdose, he is looking to destroy the Glades with his own Undertaking. In the end, he is talked out of his actions by Oliver. Tommy is later vaporized during Earth-2's destruction from anti-matter.
