Dr. Nathaniel "Nate" Heywood is a historian, specializing in deductive historical reconstruction. Due to his skills, he was able to deduce that an aberration-created reality, one in which the Nazis bombed New York City in 1942, due to the machinations of Damien Darhk and Eobard Thawne, and World War II continued until 1947, was starting to cement in the timeline, supplanting the previous reality. With the help of Oliver Queen, he was able to locate the submerged Waverider in 2016, waking Mick Rory from time stasis. Together with Mick, Nate traveled through time, using his skills as a historian to find the locations and time periods in which different members of the Legends team were stranded.
For his support, Nate was made a new member of the team. After being injected with a biomolecular enhancer created by Eobard Thawne and modified by Ray Palmer, Nate gained the ability to transform his skin into steel, making him extremely strong and resilient. After learning to use his abilities he was given the codename "Steel" by Ray, after his grandfather Henry Heywood/Commander Steel. Among the other nicknames he suggested himself were Corporal Steel, Mr. Steel and Citizen Steel.
