Prometheus's powers and abilities
Peak Human Condition
Adrian was in incredible physical form after training for four years to defeat Oliver Queen, with his physical conditioning allowing him to fight the extremely seasoned and trained vigilante on equal footing and even at times outmaneuver him. He is strong enough to easily pin down the likes of the large and physically imposing Tobias Church and Earth-2 Laurel Lance, both with one arm, and kick Oliver through a wooden wall with one leg. Adrian also withstood a severe beat down from Oliver which left his face bloody and swollen, and barely seemed fazed by it.
Acrobatics
Adrian was able to move and scale down walls with great dexterity and grace, even while simultaneously dodging bullets and throwing his shuriken.
Honed Senses
Adrian had sharp senses, easily able to pick up danger and read the atmosphere around him. For example, he quickly sensed the arrival of Green Arrow at a crime scene and immediately deduced when the US marshals guarding him learned his identity by their silent reactions without turning around.
Master Combatant/Martial Artist
Adrian, like Oliver, was an incredibly skilled fighter trained by Talia al Ghul, with a fighting style incorporating several moves that Oliver knew. Adrian was able to single-handedly and quickly defeat Evelyn Sharp and Curtis Holt with ease, as well as overpower Vigilante. During all his battles with Oliver, Adrian proved capable of fighting on equal terms with and even sometimes gaining the upper hand over him. Adrian managed to defeat Oliver in their first and second altercations, although it should be noted that in the latter fight, Oliver was caught off-guard due to Felicity Smoak being in danger. In their third confrontation, Oliver dealt a more severe beating to Adrian and the two fought to a draw in their fourth confrontation. Ultimately, Adrian was overpowered by Oliver in their final duel. Nonetheless, Adrian's skill marked him as one of the deadliest fighters in the multiverse.
Expert Swordsman
Adrian was well-trained and accomplished in the art of swordsmanship, often using his sword fighting skills in conjunction with his melee skills. He was capable of using his sword to trade blows with Oliver whilst the latter used his bow.
Expert Archer
Like Oliver, Adrian was a trained archer, although he seems to prefer throwing weapons. Adrian is skilled enough to either wound or kill his targets with arrows. While torturing Oliver, Adrian fired three arrows in his shoulder in a tight pattern at point-blank range.
Master Knife Wielder
Adrian was highly proficient in throwing weapons such as knives, battle axes, flechettes and his weapon of choice, shurikens. He was able to use shurikens to disarm police lieutenant Sam Conahan of his gun while jumping of a ledge and perfectly split an arrow shot at him by Oliver in half by throwing a shuriken. He even precisely threw a pen into a marshal's eye from across a room. Adrian was also a capable knife wielder in close combat, as shown during a confrontation with Oliver.
High-Level Intellect/Master Tactician/Expert Investigator
Adrian was a highly effective tactician, with his tactics against Oliver being at a psychological level. He was successful in tricking Oliver into killing Billy Malone, knowing that Oliver came with the intent on killing the former. Adrian one of the few people to ever tactically outsmart Oliver, who is a master tactician in his own right. Adrian positioned Oliver in a scenario where the latter was forced to proclaim his "Green Arrow" identity as a police killer, making it nearly impossible for him to take Prometheus down with his alter-ego. Adrian had proven himself to be a highly skilled investigator and tracker, having learned much about Oliver and all those close to him, becoming aware of their secret identities, The List, the S.T.A.R. Labs pipeline, the Legends, and the multiverse. He was very skilled at locating people, as he was able to track down the elusive Talia al Ghul and William Clayton, despite Samantha Clayton's best efforts to keep him hidden and safe.
Computer Specialist
Adrian had demonstrated a high degree of computer skills, as he was able to build and use several theatrical traps which he used against Oliver and Team Arrow. Oliver also mentioned that Adrian has managed to erase all traces of his birth identity, "Simon Morrison", from the internet.
Explosives Expert
Adrian had a good knowledge of explosives, quickly placing a bomb on a train before escaping, placing bombs in many rooms of a building and later having a network of C4s all over Lian Yu, linked to himself to be triggered through a dead man's switch. Adrian also successfully set off an EMP strong enough to shut down the entire Arrowcave.
Master lawyer
As the former district attorney of Star City, Adrian was a highly capable lawyer, having prosecuted a number of criminals, including Derek Sampson. He was able to use his legal knowledge to successfully prevent John Diggle's prison transfer. Considering the fact that he only became the district attorney to get close to Oliver, it is possible that Adrian did not even possess a legitimate law degree, making his knowledge potentially even more impressive.
Master Deceiver/Manipulator
Adrian was a master at deception, letting Oliver believe he was a man with a normal life as a lawyer as they often saw each other at work, as Oliver only found out who Adrian really was through Talia. Adrian was also very manipulative, able to use Evelyn Sharp's increasing resentment with Oliver in order to convince her to betray him.
Master Interrogator/Torturer
Adrian was a highly skilled interrogator, trained in both verbal and physical extraction techniques. As a lawyer, Adrian was successfully able to flip one of Eric Dunn's men to find him. While torturing Oliver, Adrian used the same methods of Oliver used to hurt his enemies, including water-boarding and shooting him with arrows, all while not killing him. At the same time, Adrian psychologically tortured Oliver by threatening his loved ones and seemingly killing Evelyn in front of him. Adrian was eventually successful in breaking Oliver, a feat that no other villain except for Slade Wilson has accomplished, and even convinced Oliver to temporarily end his crusade until Diggle snapped him out of it.
Skilled Metalsmith
Adrian has stolen several of Oliver's arrows that he left behind during his vigilante career and melted them down to be reforged as his own weapons, mainly his shurikens, showing he was a skilled crafter. Adrian's shurikens were shown to be quite sharp, as they could split Oliver's arrows in half.
Indomitable Will/High Pain Tolerance
Adrian had a high tolerance for pain, as he could keep fighting without slowing down after Evelyn cut his arm and barely flinched after being shot in the shoulder with a bullet. Adrian was still able to move his arm normally even when the bullet wound reopened. Adrian also had a high tolerance to drugs, as he was able to quickly shrug off the effect of the diazepam-ridden dart that Oliver threw at him.
Stealth/Infiltration/Escape Artist
Adrian is highly skilled in the art of stealth, as he is able to ambush his targets fairly quickly without them noticing, whether it was day or night. He was able to sneak into Gay Eked's home, a moving subway train and S.T.A.R. Labs without triggering any alarms, an act that went unknown to Team Flash for 3 days.
Intimidation
Adrian possessed an intimidating presence due to his ruthlessness, with Church, Evelyn, and even Laurel, a meta-human, showing signs of fear towards him. Adrian's killings as the "Throwing Star Killer", combined with media rumors and his presence, was enough to cause a city-wide panic. Even Darren Coffman stated Adrian was "terrifying".
