Gabriel Reyes, born into a family of private investigators, goes through rigorous training and one day is thrust into the Overwatch organization to investigate a strange plague called the Sylar. He takes on the mantle of Grim Reaper, the oldest Reaper who can still produce offspring even with his physical body.
This is a big loss for the Overwatch since he is the only one left to guard the children. But after a few years, he and another Reaper, D.Va, are awakened to their responsibilities. During this time, they learn how to communicate with each other by making body language as well as basic communication gestures. The two continue to work together and successfully evacuate the children in a helicopter when they are told to evacuate due to the Sylar’s impending attack.
During this time, D.Va learns that she has been paired with Soldier 76 as the two have various reasons to be together. She has also learned that Gabriel is actually the children’s father.
Death is the only thing that can bring back these children but when they meet, they develop a bond that allows them to help each other fight the impending Sylar threat. Death is angered when one of the children tells him that the other is his son and brings him an uncomfortable look.
She shares a lot of heavy connections with Soldier and her secret comes out. Death is certain that the children are not fake and is very upset at this revelation, but she still loves them.
She and Gabriel go on to investigate some rogue Reapers and discover that they are the work of the renegade government agency and they are trying to capture the survivors of the M.O.D. Annette’s attack and they are about to use the Infiltrator to stop it.
She helps her friend, by giving her some help from inside the agency which is being run by the highly trained Colonel Glenn Talbot, to defeat the renegade Reaper and rescue the children. Death is shot in the leg during the fight and stays at the hospital while the Reaper escapes.
Her leg injury is a grave accident, and the doctors want to remove it, but she refuses to allow it. She is being forced to leave and the doctors tell her that she will never walk again.
Death is devastated by this and she sets off to rescue the children herself. She rescues the four children and both her legs are replaced with artificial ones. She leaves the group of Reapers for good and meets D.Va and Team Widowmaker who wishes go with her.
She travels through Eastern Europe with Death, working with people she met in her own journey. One night, a team of Sombra freaks stop her and interrogate her, forcing her to reveal the location of the Sylar. They are willing to use her in a plan to take the child from Overwatch and keep him safe from the ruthless Reaper.
Death is surprised by this and warns her that she will be sent to die. Death agrees and takes her through a tunnel to a cave where the Sylar awaits. D.Va gives her a sniper rifle and tells her that Death has to kill the Reaper in order to save the child.
