Nate Heywood (Earth-Prime)/Android

"We have one job, and that's to protect the timeline. And kill anyone who messes with it. So I guess we have two jobs."

- Nate Heywood

Nathaniel "Nate" Heywood, better known as Citizen Steel, is the robot replica of Nate Heywood. Nate initially served as a member of the "real" Legends of Tomorrow and was programmed to be the "muscle" of the team, trying to hunt down their android counterparts according to Gideon's orders. He was then revealed to the truth that his team was in fact the true android Legends, though continued to serve under Gideon as the Captain of the Waverider and the leader of the Legends.

After facing the true Legends in Sarajevo, Nate was stuck in the 1914 time loop, replacing Eobard Thawne's position as the guardian of the Fixed Point.

Creation
In hopes of creating a robot army against the Legends of Tomorrow, Gideon created a replica of Nate Heywood, alongside other Legends.

Strong as Steel
With no knowledge of his identity as a robot, Nate and the Legends traveled to Seattle and ambushed the "robot" Legends after they held a party. Nate then expressed frustration over his inability to kill them before they escaped on Gwyn Davies' time machine.

Afterwards, the Android Legends returned to the Waverider and discovered that the Legends' actions in Chernobyl led to severe aberrations. Nate and the field team then abducted Kalashnik from his convoy. They threatened him and forced him to issue a broadcast to tell people not to panic over the upcoming Chernobyl Incident, as they are hoping to ensure the number of casualties remain the same as the original timeline.

Eventually, the Legends were able to fix the aberration and returned to the Waverider waiting to witness Sara's assassination of Irina Petrov. However, Nate was frustrated that he was unable to see the actual murder on the live video, though was unaware that Sara did not murder Petrov. Hours later, Sara held Dr. Sharpe with a knife and revealed that the Legends are in fact robots. Nate initially thought that it was merely a test and soon faced the facts. Unfortunately, Nate remained stubborn and continued to work for Gideon, replacing Sara as the captain of the Waverider.

Captain of the Waverider
As the captain, Nate's first mission is to lead the Legends to 1914 after detecting the assassination of Franz Ferdinand was prevented. They were then faced by countless time travelers whose charged at the team. Nate and the Legends then massacred the group, only for the real Legends to step out and distract them. Nate and Sara pursued their human counterparts, though allowed them to escape as Gideon ordered.

Nate and Sara soon pursued Eobard Thawne in a building, following Gideon's orders to kill all time travelers. Sara then murdered Thawne as she confused him with her human counterpart. With no way to escape, the real Legends offered to talk, though Nate did not listen to the real Sara's proposals and decided to attack them. He was unsuccessful while Gwyn Davies brought Sara to safety.

In the end, Nate and Sara returned to the tavern and confronted the Legends before he was ordered to remove his CPU by an imposter Gideon. His CPU was then inserted back to his body with his human counterpart bragging about his supposed role as the guardian of the Fixed Point, making android Nate jealous and taking the Time Manipulator for himself. As a wormhole opened, Nate realized that he had made a mistake before being sucked into a time loop, replacing Thawne's position as the guardian of the 1914 Fixed Point.
