"Guys, the manual mentions an obscure scientist who laid the foundation for all of time travel, a guy named Dr. Gwyn Davies. He's alive right now, in 1925, and he lives in New York."
Ava Sharpe on Gwyn Davies[src]

Dr. Gwyn Davies is a scientist known for laying the foundation of time travel.[1] He resided in New York City, until being recruited by the Legends to help them get back to the present.


Early life

At some point, Alun Thomas and Gwyn became best friends. Alun managed to light up a room with a smile and wrote Gwyn the most delightful poetry. During their friendship, Gwyn developed feelings for him.

A few years into World War I, Gwyn and Alun were tasked with delivering a letter to a unit, but along the way, Alun got killed. By the time Gwyn arrived at their destination, all the members of the unit had died. This prompted Gwyn to begin work on a functioning time machine.[2]

Assisting the Legends

Gwyn in the mental asylum's bed.

Gwyn was walking out of a building when Sara Lance started speaking to him, stating that she was intrigued by his work. He wasn't interested, but Sara made him fall so she could steal of of his plans for a time machine. Later, to distract him, Sara impersonated a secretary gave him many files to sort. However, Gwyn was caught by Thomas Edison, and was promptly sent to a mental asylum for insanity. He was broken out by Sara, and they both made a deal to assist each other.

Gwyn and the Legends use his time machine to escape a rogue Waverider.

Gwyn then attempted to use his time machine to time travel, but was averted by Astra Logue, who knew the attempt would result in failure, using magic to shut down the city's power grid. After acquiring the part needed for the time machine to successfully time travel from J. Edgar Hoover's robot, Gwyn activated the time machine with him and the Legends inside. They landed in an unknown time period, in what appeared to be a wild forest.[3]

The Legends and Gwyn arrived in 1986 with the time machine. Everyone started panicking, so Nate Heywood gave everyone orders and told Behrad Tarazi and Zari Tomaz to go with Gwyn. Gwyn ran away, so Tomaz and Behrad went to talk to him to convince him to fix the time machine, but Gwyn got frustrated and mad, so he dismissed the comments and left again. Tomaz followed him and wanted to talk, so Gwyn expressed what happened to him during the war and how he felt. While talking, some soldiers arrived, making Gwyn start panicking, so they took them in.

Gwyn and Zari talk about their past.

Once in the room, Gwyn continued talking to Tomaz about his best friend Alun Thomas and how he felt God forgave his past sins by giving him another chance at saving him. He told Tomaz, Behrad's attitude reminded him of Alun. Zari asked Gwyn if he loved Alun, and Gwyn confessed he did. Once Behrad arrived, he gave Gwyn the missing parts for the time machine and announced they were in 1986, and the Chernobyl explosion would happen today. They got out, but Gwyn said they needed to do something to save the people, so Tomaz agreed, and they announced to everyone to leave. They stole a car and reunited with the Legends. After arriving, they told the Legends of the events that happened. Once Tomaz, Behrad and Gwyn fixed the time machine, the Waverider that was hunting them appeared again, so the Legends hurried and used the time machine.[2]

Gwyn asking Ava Sharpe about John Constantine.

The Legends managed to escape the Waverider that was hunting them, but they didn't know where they were because Gwyn's time machine broke when Bishop crashed into the time machine on a toilet. Some military men were near the area, so the team distracted them and entered the pocket dimension. There, they questioned Bishop and learned about "evil Gideon". They sent Bishop to Constantine's room, making Gwyn curious on who he was. To fix Gwyn's time machine, Sara and Ava went to McDougle Jemison Factory, where they could get the missing parts.

When Ava and Sara got back, they revealed they were in the 1940s. After hearing the news, Gwyn saw how the Legends celebrated Tomaz and Nate's moving-in together announcement. Sara, Ava, Gideon, Astra, and Spooner joined the Rosies, so Gwyn could the needed parts to fix the time machine. After the ladies brought the missing parts, Gwyn asked Gary to help him out. While fixing the time machine, Bishop, Gideon and Behrad arrived and showed Gwyn a neural navigational system that Gideon could use to navigate the time machine, by reading her mind. Since the Legends accidentally changed the timeline, "evil Gideon" found them and sent robots after them. The Legends were able to escape when Bishop sacrificed himself.[4]

Gwyn talks with Spooner.

The Legends arrived in the pocket dimension since it felt like home to Gideon. Gwyn took a moment to process Bishop's death and asked if they could time-travel back, but Sara said Bishop sacrificed himself. Gwyn was using a candle when he heard voices thinking it was Alun. Gwyn opened the doors to Hell and fainted. Spooner and Astra found Gwyn and calmed him when the weird voices appeared again. The team told Gwyn to be careful with the doors next time, as something could have entered. They then heard Sara scream and found Gary and Gideon in bed. After asking them how long they had been together, Astra cast a spell and it revealed that the Legends were on a reality show controlled by a cursed film crew who were employed by Harris Ledes, making Gwyn faint once again.

Gideon talks to Gwyn about Alun.

Spooner and Gwyn talked about the Hell crew, and soon after, Spooner asked Gwyn if they allied but quickly decided not to since Gwyn was weird. Gwyn went with Sara again to speak about his secret mission to save Alun, and Sara made a post-it which she gave Gwyn to confirm she would keep her promise. When Gwyn was walking, Spooner came out naked, making him uncomfortable. When Gwyn was reading, Gideon arrived. The latter and Gwyn talked about Alun, giving Gwyn an idea. Ava summoned the Legends to dinner and they all expressed their emotions through a "personal interview". Everyone was awkward with each other. Gwyn started praying while Zari thanked Ava for the meal. Gwyn told everyone that he wanted to save Archduke Franz Ferdinand, since Sara promised him that he could save one life. Sara then got mad at him, calling him a liar.

The Legends hear Behrad's feelings.

Soon after, Gary told the Legends that Gideon was going to kill them and grabbed the neural navigational system that Bishop had made. They chased Gary but were too late since Gary ate the device. The film crew's curse got lifted because Behrad got "real", expressing his feelings over his deaths and how he felt about Astra and having cameras in his face early on in his life. Gary summoned a house meeting and told everyone to apologize to him and Gideon over what they said about their relationship. The Legends all apologized and asked Gideon where they should go. Gideon told them that her plan was to plot a course for the assassination of Archduke Franz Ferdinand in 1914 in Sarajevo in order to save him and stop World War I. The team laughed thinking she was joking, but freaked out when they realized that she was serious.[5]


"God forgive me, I loved Alun more than anything."
—Gwyn Davies[src]

Gwyn is a very vulnerable and neurotic man. He has passed through multiple traumas. He was a soldier, who lost his best friend Alun, prompting him to make a time machine. Although Alun was his best friend, Gwyn had feelings for him and was hurt when he died. When he made a deal with Sara Lance, he was shocked to know she was married to a woman.[3] Since working with the Legends, Gwyn has had a new enviroment, with a more accepting group. Gwyn has bonded with Zari Tomaz, talking about the death of his late friend, Alun.[2] Gwyn has trust issues as seen when he was talking to Sara, and kept asking about the deal they made to save Alun.[5]
