The Flash Wiki

"Any time you need me, I'll be there for you. I couldn't run like your dad, but I'll be there in a flash."
—Barry Allen to Shawn Allen

Bartholomew "Barry" Patrick Allen is a forensic scientist for the Central City Police Department. After his lab was struck by lightning and he was doused with chemicals, he gains the ability to move at superhuman speeds. Originally intending on using his abilities to bring his brother's murderer to justice, he later becomes the hero of Central City known as The Flash.


Early life

"Crime Lab. Want to film us pouring plaster into tire tracks?"
—Barry Allen to Linda Park

Barry Allen was born to Henry and Nora Allen. He had a brother, Jay. Both he and Jay decided to join the CCPD, following their father's footsteps, however Barry joined the crime lab while Jay became a commander.

Becoming the Flash

While celebrating his brother, Jay Allen's birthday with the rest of his family, Barry was summoned to the crime scene at West Ridge after the aftermath of recent bombings by the Dark Riders. Later, Barry and Julio Mendez both work in the lab, examining soil samples they took from the crime scene. Eventually, Julio begins to fall asleep and is sent home by Barry. While he's working, lightning strikes Barry's lab, dousing him with chemicals from a nearby shelf. Barry is then found by Julio on the floor, and taken to the hospital. He leaves the hospital the next morning as all the tests the doctor ran tested negative, going to Hudson Diner with Iris West. After the two get into an argument over marriage, Barry leaves back to the lab, and while there receives a call from Dr. Lawrence, who informs him that there was cell damage from Barry's accident, and not knowing what to make of it, sent the results to S.T.A.R. Labs. Barry angrily informs Julio of this and refuses to have anything to do with S.T.A.R. Labs, as one of their employees died last year in one of their experiments.[1]

Despite this, Barry still showed up at S.T.A.R. Labs, meeting Dr. Tina McGee and learning that the employee who died was her husband, David. Barry then agreed to take the tests, and found out that after the accident, he now had super speed.

"I think I'm starting to like this."
—Barry Allen

Barry, with the help of Tina, learns how to control his abilities at a S.T.A.R. Labs Testing Facility using a prototype suit. However, he soon finds his brother Jay Allen dead at the hands of notorious criminal Nicholas Pike. After Jay's funeral, Barry decides to use his abilities to stop Pike and his men, donning a new suit made by Tina. He stops Pike's men and fought Pike himself. Despite Pike initially having the upper hand, Barry manages to knock out Pike with electricity and left him for the police. He then decided to continue fighting crime as the Flash.

Later, he investigates the murders of several homeless people along with Julio, and manages to link this to Tina's old friend, Dr. Carl Tanner. When Barry confronts him as the Flash, he injects himself with a serum and turns into a monster, the Nuge, and knocks out Barry. Barry wakes up in time to save Tina, and chased after the escaping Nuge, trapping him with a metal fence.

A private investigator named Megan Lockhart manages to discover Barry's identity as the Flash. Barry is blackmailed by her employer, Thomas Castillo, to comply with him. Barry, however, secretly collects evidence about Castillo's crimes. When Castillo is killed by his associate, Lockhart gives all her evidence to Barry to protect his secret, having grown fond of him.
