Irey West, also known as Impulse, is the daughter of the third Flash Wally West and Linda Park. She was erased from history and lost for years in the Dark Multiverse before finally coming home.


An instant before the Flashpoint altered reality, Irey and her twin brother Jai were sucked into the Dark Multiverse by a tide of dark matter. Wally attempted to save them but was too late. Ten years were removed from history, which included Jai and Irey’s birth, and all memory of them was erased. Wally himself was lost in the Speed Force immediately after and Linda forgot both him and her children.[1]

Dark Multiverse

Irey and Jai were trapped on a planet in the Dark Multiverse created from their father’s fear that he would never see his family again. Wally eventually found his children, only to learn that he couldn't destroy the planet on his own. He agreed to join with the Mobius Chair to save the Multiverse in exchange for Tempus Fuginaut to take Irey and Jai to Earth 0. He integrated them into Earth 0's history and they were reunited with Linda, who had her memories of her family restored.[2]

Legion of Zoom

She and her brother later answered Max Mercury's call from the Speed Force to help him and the Flash Family battle the Legion of Zoom. Irey had a brief exchange with Bart Allen, who accused the other of stealing the Impulse identity. The younger members of the Flash Family figured out that if they disrupt the time-displaced villains' frequencies, they would return to their proper times without any memories of their time among the Legion.[3]

Death Metal

Linda, Jai and Irey took refuge in the Speed Force alongside the rest of the Flash Family when The Batman Who Laughs remade the world in his image. They briefly reunited with Wally when he took the Mobius Chair into the Speed Force to keep it out of The Batman Who Laughs’ clutches.[4]

Infinite Frontier

After the events of Dark Nights: Death Metal, the Park-West family began to rebuild their lives. Jai and Irey were traumatised by their experiences and had recurring nightmares, but these subsided as the family gradually returned to normal.[5] Wally began to teach Jai and Irey about being a superhero, although he was reluctant to let them in the field, even confiscating Irey's Impulse costume.

Wally took Irey to Terrifictech's Daddy-Daughter Dance, but they arrived to find all the other attendees unconscious. A disgruntled former employee called "Doctor Nightmare" had attacked the dance with sleeping gas and a helmet which allowed him to make nightmares real. He used the attendee's nightmares to rob the vault where Mister Terrific kept the research he considered too dangerous to release. Due to their super-accelerated metabolism, Wally and Irey were not put to sleep by the gas but were unable to use their powers. Wally told Irey to stay in the car while he stopped Doctor Nightmare but she convinced him to let her help and stole the helmet while Wally was still deciding what to do. Nightmare noticed what she was doing and they were forced to flee and hide in a storage closet from the nightmares. Irey suggested she could use the helmet to bring her dreams to life and fight them. Wally sang her a lullaby and she fell asleep, bringing her dreams to life: a human-sized soldier girl action figure, a two-headed bunny, a robot lion, a panda with a mirror in its torso and a gummy dog. They fought off the nightmares and Wally knocked out Doctor Nightmare. Wally took her home as it was late but with their powers restored they stopped off in Paris to dance in front of the Eiffel Tower.[6]


Irey West as an adult

In a possible future glimpsed by Doctor Manhattan, Irey joined the Flash Family and became a full fledged superhero as the new Kid Flash.[7] Following an adventure where he became a disembodied consciousness within the Force and began jumping into the bodies of other speedsters across time and alternate realities, Wally West informed his children that he would one day hop into Jai's body. Twenty years after the adventure, Wally fulfilled his prophecy and became Jai, where Irey was waiting for him. She told Wally that his family were safe and happy in the future and that she was happily married. Iris also revealed that she and Jai had grown up to be superheroes themselves.[8]
