Wally West

Wallace "Wally" West is the son of Joe and the late Francine West, and the younger brother of Iris West. He is a champion drag-racer under the alias "Taillights".

Biography
Francine West gave birth to Wally 8 months after leaving her family. Francine and Wally lived in Keystone City, where Wally started participating in street races and gained a reputation as a winner. Other racers stopped wanting to face him, so he started racing in Central City in order to pay for his mother's medical bills due to her being sick.

Visiting his father and sister
During a Christmas party in 2015, Wally stopped by to visit Joe and Iris. He realized they had company and apologized for the timing but was invited into their home.

Iris and Joe showed Wally around the Central City Police Department earlier before their plans to have dinner that night, where it became evident that Wally held bitter resentment towards Joe for not being in his life. However, Wally stood Joe up and was later found by Joe participating in a street race, which he won. Wally told him that he has been doing street races in order to pay for his mother's medical bills, as he had had to be the man of his household all of his life due to Joe's absence. Joe offered to dip into his bank account to help Wally but he angrily rebuffed the offer. Later that day, he visited Joe and reassured him that an apology wasn't coming, before letting him know he was returning to Keystone City. Joe apologized for trying to push the "father-son" thing so hard before they sat down to a meal of Chinese food.

When Francine's state worsened and she was about to die, she told Iris she would like Wally to visit her so she could see the whole family together. Iris went to see Wally to talk about her and he said he was angry because his mother never told him he had a father and a sister. Iris mentioned she never had the opportunity to say goodbye to her fiancé before he died and told Wally he should go see his mother while he still could. Wally decided to follow her advice and asked Iris to go see Francine with him.

Francine died soon after and Wally grew closer to Joe and Iris. Iris started to worry about the dangers of Wally's street races and complained that Joe was acting more like a "buddy" than like a father to Wally though Joe explained that he wanted to give Wally some space and not be strict with him to avoid jeopardizing their relationship. Iris tried to talk some sense into Wally and even threatened to publish an article about street racing. She and Joe were at one of the races when a metahuman able to merge with asphalt attacked one of the racers. Wally was saved by The Flash, but Iris got injured by a glass shard and had to be taken to the hospital. Wally visited her there and Joe had a serious conversation with him, saying they were worried about him because they were his family and that he should have treated Wally as a son instead of as a friend. Wally decided to stay with Iris at the hospital and told her he liked street racing because it reminded him of the times when his mother would take him for a drive, which is why he did not want to stop racing.

Joe attempted to help Wally and Barry bond by having him help Wally on a technical project to enter college. Wally became annoyed with Barry's revisions to his project and after being questioned by Barry if he had a problem with him, Wally revealed his jealousy over Barry's perfect life, getting to be raised up in Joe's home and being bragged about so much by Iris and Joe but they are interrupted by King Shark ripping the roof of the West home open in search of The Flash. When Barry stumbles back down the stairs after fighting King Shark and to cover his tracks as The Flash, Wally calls him a coward for hiding during the attack and leaves when Joe stops the altercation. While at CC Jitters, Joe tells Wally about Barry's mother being murdered when he was eleven and his father being wrongfully accused of her murder and that he had given Barry all the love and care he deserved and that while Barry is flawed, the reason they brag on him so much is because it could have been worse and that he is loved just as much as Wally and is also his son too.

Moving in
At a later night, Wally came over to see Joe and watch Formula 1, and to do some laundry. He told Joe and Barry that he had moved out of him campus because the rent became too expensive. Joe offered to pay for some of it but Wally claimed it was fine. Later when watching the formula 1, Harry came over and wanted to speak to Joe, Wally claimed he looked like Harrison Wells, but Harry denied being him and Wally left. The next day Wally came back and Joe offered him a place in his house, which Wally quickly accepted. Later, Zoom raided the house and took Wally to his base on Earth-2, who claimed the only person able to help him, is The Flash. After The Flash struck a deal with Zoom, Wally was taken back to Earth-1, and taken away from Zoom.

After being saved by the Flash, when the Flash traded his powers for Wally's life, Wally was inspired by the Flash's sacrifice and figured out that Joe had a way to contact the flash from what Zoom told him while he was in captivity. Wally asked Joe if he could arrange a meeting with the Flash so that he could thank him. Later on during a night, Joe brought Wally to the rooftop so that Wally could thank the Flash for saving him in person.

When Zoom reappeared on Earth-1 to instill fear into the CCPD, Joe and Harry had both of their children (Wally West and Jesse Quick) kept safe in the Time Vault at Star Labs since they were both kidnapped by Zoom before. Wally and Jesse quickly bonded during their time in the vault. While Wally was trying to break out of the Time Vault, Jesse stated the improbability of the wall just opening for him. Wally said that they should be outside trying to help the team rather than just hiding. Jesse, feeling hopeless, saw no way that they could actually be of use. Wally rekindled that hope by saying that she was smart enough to solve an unsolvable problem. Convinced, Jesse said that she will try to see what she could do. Later on, they were able to break out of the Time Vault just in time for an earthquake caused by the experiment to restore Barry's powers. Seeking the cause, Wally and Jesse went into the halls to investigate only to be blasted by a wave of Dark Matter energy from Barry's apparent death when he seemingly exploded by the attempt to restore his powers. They were both knocked out by the wave of energy.

Personality
At first Wally came off as a rather apprehensive and unsure young man when first exposed to his father and sister, but his full personality came to light in time; he is an eager, reckless, competitive, and somewhat angry young man. His anger came from having grown up with no father, having to be the man of the house from the very beginning, and taking on far more responsibility than he might have had to if he'd been raised by both parents. Despite his rage, Wally deeply loved his mom, being afraid to see her pass away and working constantly to both pay her medical expenses and to keep his mind off the pain of his impending loss and grief. Only once Iris talked him into it could he face his demons in the form of saying goodbye to his mother. His competitive side is seen not only in his racing career, but also in his initial interactions with Barry, feeling jealous of the constant praise Barry received from Joe and Iris and envying Barry having been raised by Joe. This one-sided rivalry came to a halt after Joe revealed why Barry came to live with him and Iris and that Barry's tragedies are why Joe tried to hard to defend him from any criticism. After this, Wally made the decision to try to see Barry less like a rival for his father's affection and more like a brother.

Abilities

 * Skilled engineer: Recently it is revealed that Wally is currently working on a turbine supercar that that would run on shit, and has a well-lit background with certain fields and branches of engineering and mechanics that he could hold an on par debate concerning both his project and the field in general with his foster brother Barry Allen.
 * Drag racing: As a method to pay his late mother's medical bills and a solution to cope with his grief Wally took up the sub-hobby of participating in drag races and was well regarded and known to the field to the point where no resident residing in Keystone would challenge him to races any longer, and became rather popular and well known in Central City. He is referred to by the alias of "Taillights", most likely because his opponents see a lot of his taillights during drag races.
