Tyler was an agent at Crows International, where he met Sophie Moore. They fell in love, though Tyler remained unaware of Sophie's true orientation and romantic past, eventually marrying at some point in 2015. Tyler was well-respected by his mother-in-law, Diane, who praised his decorated career and how he never forgot her birthday. Despite this, Tyler recognized that Diane was a very hard woman with Sophie.
Agent of Crows International
After Sophie was rescued by Batwoman from Alice and the Wonderland gang, Tyler returned to Gotham City to check up on her. After reuniting with Sophie, relieved she was okay, he met his wife's old friend, Kate Kane.
Weeks later, Tyler accompanied Sophie to a party thrown by Tommy Elliot. Sophie volunteered to be security for Mary Hamilton who was invited there. Tyler saw Kate and asked how she knew his wife since Sophie never mentioned Kate before. Kate, realizing that Tyler did not know his wife's past with her, replied that they were good friends at Point Rock Academy.
Later, when Jacob Kane called for "Moore" to collect Mary, both he and Sophie answered and got the girl. Together, the three were trapped inside a deactivated elevator when Tyler questioned Sophie about why Kate was never previously mentioned, even though she is the daughter of Sophie's boss. Mary stopped the argument by suggesting that the two agents should be trying to pry the doors open, which they did. Tyler went to see if he could help others.
Weeks later, Tyler watches the news report by Dana Dewitt on the death of Angus Stanton. When Jacob asks him why the news knew about this before the Crows, Tyler shows Jacob footage of the Bat-Signal being used by the GCPD instead of calling them for assistance. After listening to Jacob's speech degrading Batwoman, Tyler worked with him to try to identify the Executioner, but he was distracted by a report that the costumed killer was on Rucka Avenue.
The next night, Tyler helped to capture Chris Medlock. As the Crows escorted Medlock to a police vehicle, Tyler watched as Batwoman took the prisoner. Tyler took command of the Crows team to find the two.
Problems with the marriage
Though Sophie had disappeared for a while, Tyler was busy with Jacob.
One morning, Tyler and Sophie were at work when he accessed footage of Sophie having a conversation with Batwoman in an alley. Tyler questioned his wife about it because she had said that the vigilante fled before they could talk. Tyler, who felt that Sophie was hiding secrets, asked her if she knew the secret identity of Batwoman, to which Sophie said that she did not.
Later, Sophie returned from "running an errand" and told Tyler her past with Kate at Point Rock. Tyler did not like that she kept hidden such an important part of her past, to which she revealed that she had not even told her mother. However, when Tyler asked if her "thing" with Kate was over, Sophie hesitated, hurting Tyler.
The next day at work, Sophie kisses Tyler and tells him that he is her love and Kate is the past.
A couple of days later, Tyler and Sophie discuss taking a vacation from the Crows while in the office of Jacob; Tyler is aggravated. "Jacob" arrives and wants to plan the security for the gala honoring Catherine Hamilton-Kane. The two are tranquilized by the impostor. They awaken to find themselves tied up in the sound-proof room. As the two contemplate Alice's motives for not just killing them, the subject of Kate's love for Sophie is discussed. Tyler suggests that they free themselves and uses Sophie's engagement ring to cut their binds. Tyler continues to ask Sophie about her past, but, when she answers, he feels that she is being evasive about what he truly wants to hear.
Later that night, after Jacob's arrest, Tyler talks to Sophie and states he doesn't want to waste his life fighting for something he can't have. Tyler bluntly asks Sophie if she is in love with him, to which she finally admits she doesn't know. Tyler then leaves her to give Sophie time to figure out whether she wants the same future he envisions.
During the Anti-Monitor Crisis, Tyler as well as everyone in the multiverse except for the seven Paragons, was killed in an antimatter wave by the Anti-Monitor on December 10, 2019, only to be restored a month later, after the Paragons and the Spectre created a new universe.
Tyler and Sophie were still separated, which prompted Diane to visit her daughter and express disappointment at Sophie's marriage falling apart.
At some point, Tyler and Sophie officially divorced.
Tyler openly expressed love for his wife Sophie and was friendly towards others, including individuals who were acquainted with Sophie, however, after Sophie revealed her sexuality and past relationship with Kate Kane, Tyler was upset at Sophie for not informing him earlier on. Believing that Sophie only married him to please conventional society views, it caused their marriage and relationship to slowly fall apart. Tyler later told Sophie that he wanted a traditional family, like a simple house and a pet, but revealed he did not want to try to achieve those things due to Sophie's sexuality and being in love with someone else.
When Sophie did not give him a proper answer on whether she loved him or not, Tyler decided to end his marriage with her so she can figure out what she wants to do with herself and who she wants to be with for the rest of her life.
