David Singh, nicknamed Mirror-Singh by Nash Wells, was an entity who is the mirrored doppelgänger and a cloned counterpart to David Singh. He was created by the Mirrorverse and shares the same memories as the original David although a few other traits are in opposition to his Earth-Prime counterpart. He manipulated Team Flash while secretly working with Eva McCulloch, Mirror-Iris West-Allen and Mirror-Kamilla Hwang towards an ulterior motive. Ultimately, he sacrificed himself to help Eva infiltrate McCulloch Tech and kill her husband.
Building the R.I.C.O. case
Captain Joe West of the Central City Police Department confided in David that he felt that there was a mole in the organization; Joe did not know that he was talking to a duplicate who worked for Eva McCulloch.
When agents of A.R.G.U.S. came to the police car garage, Sunshine attacked; David watched as she killed the agents. David and Joe stood back-to-back preparing for the assassin's attack when Barry distracted her and she pursued him.
David was with Cecile Horton, Barry Allen, and "Iris" at an ambulance; Joe was almost killed when his brakes failed to work. David insisted that Joe should go into witness protection. Joe declined; David told all assembled that he would never forgive himself if something else happened to Joe.
Later, David calls "Iris" and tells her that Joe is in witness protection before Barry can. 
The three went to an A.R.G.U.S. facility where Ramsey Rosso was being held. The three could visit Ramsey unguarded because of the real David's position with the police department; he merely pretended he was bringing the press for an interview. David helped to explain to Ramsey that Eva needed a sample of his blood to exit the Mirrorverse. After "Kamilla" sacrificed herself to deactivate the restraining field, Ramsey suddenly attacked "David" and "Iris", knocking him unconscious. When "David" awakened, "Iris" had the blood sample and Ramsey had opted not to escape with them.
Siding with mother
David called his lover and told him that they were no longer together as he needed to be with Eva. Then he and Eva decided to destroy everything Joseph Carver had. The first step was to burn his warehouse where he kept weapons; David killed the five guards that manned the place. As he was pouring gasoline throughout the place, Flash and Elongated Man arrived and tried to stop him. David was adamant and set the warehouse ablaze.
A memo passed by David's desk that Carver was going into A.R.G.U.S. custody; David went to the police station to intercept him. When David exited the elevator, he saw Team Flash there, so David told Barry that he would like to trade Iris for Carver. Suddenly, Nash pushed David away from Carver and Barry and teleported Team Flash away.
David was in the McCulloch Tech building when he saw Barry Allen attempting to protect Carver. He told Barry that he only lived for the will of his mother before he disintegrated into a weaponized Eva who blasted Barry unconscious.
David had no personality outside the will of his creator; this fact is so apparent that Ramsey Rosso was disgusted to be around such an unliving thing. However, David's impersonating skill was incredible, as no one, including Barry Allen or Joe West, who have worked with the real David for years, noticed the difference.
He was staunchly loyal to Eva, since he refused to listen to Barry's pleads to stop cooperating on Eva's plans by appealing on the David Singh Barry worked for. He constantly called her a mother and kept attempting to convince Barry to let Carver die.
