Bart West-Allen (Earth-Prime)

"Sometimes you have to take a risk. Sometimes you have to go with your gut, and is it impulsive? Maybe. But sometimes it’s right."

- Bart West-Allen

Bart West-Allen is the son of Barry Allen and Iris West-Allen, the younger brother of Nora West-Allen and the vigilante known as Impulse.

Early Life
In 2030, Bart West-Allen was born to Barry Allen and Iris West-Allen. His parentage means that he inherited a natural connection to the Speed Force, which gives him various superhuman abilities, including the ability to run at superhuman speeds. At some point, West-Allen met the Speed Force, who appeared as Nora Allen. West-Allen then named her "SFN", short for "Speed Force Nana".

Impulsive Actions
"He was the first person that saw my impulsiveness as a strength and not as a weakness, and he would literally tell me."

West-Allen was then trained by his father and Wally West, who taught him how to run and meditate respectively. However, only only Jay Garrick understood his impulsive behavior and taught him how to use it as a strength. Eventually, West-Allen stated fighting Godspeed, who he considered to be his "Thawne". Godspeed captured Garrick and murdered him in front of West-Allen, traumatizing him and pushing him to fight Godspeed.

Back in Time
While fighting Godspeed in the city, Nora held Godspeed with a lasso as West-Allen "phased" through his body, knocking him unconscious. Nora scolded West-Allen for his impulsive and irresponsible behavior until Godspeed woke up. They chased him across the city and found him at Flash Museum. Godspeed opened a portal using the Cosmic Treadmill and went to 2021. Despite hesitating for several seconds, West-Allen ran into the portal anyway and travelled from 2049 to 2021 alongside his sister, during the Godspeed War. Once there, he met his father in the Speed Lab and asked him if he could call him "pops" as he liked the nickname in their time.

The Godspeed Imperative
In 2021, West-Allen and Nora were informed by their father that August Heart has no memory and kept in S.T.A.R. Labs. They then met Cecile and Caitlin, who they greeted. Chester then expressed his admiration on West-Allen's battle against Godspeed. West-Allen then told him that they met in the future and Runk helped him on his differentials of mathematics homework multiple times, which West-Allen reminded him to do so in the future. West-Allen and Nora then had lunch at the lounge and saw their father looking at them. As they talked to each other about the timeline changes, they were interrupted by an alarm about Godspeed fighting near City Hall.

The Flash family then ran to the site of conflict, with West-Allen telling his father that they should wait until the Godspeed clones kill each other, and they should clean up the mess afterwards. Barry was surprised by West-Allen's violent intentions and ordered both Nora and West-Allen to run in different directions. However, the clones did not follow Barry nor Nora, but rather followed "The Adversary", West-Allen himself. Luckily, the clones had to recharge in the Speed Force and West-Allen survived the battle. Returned to S.T.A.R. Labs, Barry refused to let West-Allen return to the field until he tells him the truth of being "The Adversary" to Godspeed. West-Allen then ran to the West House out of rage.

Nora then found him in the living room and talked to him about their past. West-Allen became emotional as he talked about Jay Garrick, who was the only person that understood his impulsiveness and died before West-Allen went to 2021. The two then returned to S.T.A.R. Labs, only to be benched together when Barry and Nora were defeated. When the Godspeed clones threatened to kill Garrick unless they have West-Allen, West-Allen disobeyed Barry's orders and confronted an army of Godspeeds. He was then overwhelmed and captured by the clones. Barry and Nora then arrived and see West-Allen being tortured by the lead Godspeed, and quickly rescued him from the pain. West-Allen then fell into a coma as Cisco Ramon rescued the speedsters from danger.

All Hands on Deck
Thankfully, West-Allen was awakened when the Speed Force boosted his connection. West-Allen then saw his family and the Speed Force, telling them that he nicknamed Speed Force's form as Nora Allen as "SFN", short for "Speed Force Nana". The family of speedsters then joined forces, fighting against the Godspeed Army. West-Allen threw a series of lightning shurikens and defeated a group of Godspeeds. However, the Godspeeds soon took the upper hand and recharged from the Speed Force, who was in close proximity with them and had a strong connection with them. The family then retreated back to S.T.A.R. Labs.

Hours later, West-Allen and the rest of the team witnessed the return of Reverse-Flash, who agreed to fight Godspeed in exchange for a physical body. A week after the defeat of Godspeed, West-Allen attended the vow renewal ceremony of his parents, where he sang "1949" to them.
