Citizen Steel's powers and abilities
Organic Steel Transformation
As a result of Eobard Thawne's biomolecular enhancer that Ray altered and injected into Nate, he gained the ability to transform his entire body into steel, though Ray claims that it is actually an organic form of alloy. In this state, his body increases somewhat in height and build. Despite being entirely constituted of steel in his altered state, Nate appears to retain his normal level of mobility, leaving his agility unhindered.
Accelerated Healing Factor
A bonus effect of the biomolecular enhancer cured Nate's hemophilia. To which, Nate's enhanced body is able to recover from injuries much faster than a normal person. Even a direct hit to his chest by the A.T.O.M. Exosuit's blasters only knocked him out for a minute before he somewhat recovered shortly afterwards. Upon transforming, any injuries his body has sustained fully heal immediately.
Superhuman Durability
While transformed, Nate is far more durable than any normal human, approximately 100 times stronger than steel, according to Ray. This makes him extremely resistant to injury from low to high-caliber bullets, landmines, knives and even ion blasts from Ray's A.T.O.M. Exosuit and super-accelerated hits from the Reverse-Flash. He could also survive falls from great heights, such as when he fell from the Temporal zone, through the skies, and eventually crashed into solid ground in Feudal Japan while showing no physical injury. Nate's durability is not without limits as he can be affected by bullets or any weapons molded from Dwarf star alloy and possibly any metal/steel strong enough to penetrate his body.
Superhuman Strength
Nate is far stronger than any normal human, with his physical at least quintupled from it's normal level as stated by Ray. He was able to overpower Vixen, who was channeling the spiritual might of a gorilla, with ease and go toe-to-toe against Ray and his A.T.O.M. Exosuit. He is strong enough to lift and fling a full-grown man and even a Dominator like a rag doll, also knocking one out with a single punch (whereas Supergirl had difficulty doing so). His strength was further tested when he tried to stop a train carrying eight boxcars of Dwarf star alloy, which was moving at full speed, and was able to slow its momentum until it completely stopped in its tracks, equaling to 320 tons total including the locomotive.
Timeline Change/Reality Alteration Awareness
Nate seems to be able to sense changes in the timeline or reality itself, as shown when he detected changes to the past, such as New York City being nuked by Nazis in 1942, causing World War Two to last until 1947, and when the Legion of Doom changed reality using the Spear of Destiny, he knew someone had "operated" on reality.
Abilities
Genius-Level Intellect/Master historian/Expert Detective
Nate is a very intelligent individual, being an accomplished and resourceful historian, priding himself on deduction. With his deduction skills and extensive work with sources, Nate deduced the identities of Green Arrow and Rip Hunter's Legends, as well as the locations of time-scattered members of the Legends throughout history. Nate is very observant and sharp-witted, able to recognize that the timeline was starting to change due to aberrations, despite previously not being acquainted with the mechanics of time travel. He immediately thought to bring his findings to Oliver, the Green Arrow and mayor of Star City, requesting assistance with saving the them. Nate's talents for deductive reasoning and analysis proved their worth even in the Legion of Doom's rewritten reality, where he soon realized how the world had been unnaturally altered.
Expert Engineer
Nate has been proven to be very adept with machinery. After learning about how time travel works, he was able to design an alarm system to detect aberrations in the timeline.
Multilingualism
Nate is fluent in English, German, French, Japanese, Italian, and Latin.
Hand-to-Hand Combatant
Since joining the Legends, Nate has begun sparring with his companions (especially with Ray) to better his combat skills. Despite not being as skilled as the other Legends, especially compared to Sara, Mick, or Amaya, Nate can hold his own in a fistfight, partly because of his powers. Nate's style of fighting is mostly that of a brawler mixed with basic boxing, which he most likely learned from Ray.
Marksmanship
Nate fought decently with a rifle while undercover in the Vietnam War with Mick Rory.
Swordsmanship
Nate has proven decent at fighting with blades, as he used the blade of a paper cutter to fight and defeat a magical plant creature that Gary had accidentally brought to the Time Bureau.
