Impulse src
Bart Allen, also known as Impulse, is a speedster who was somehow trapped in the Speed Force and forgotten to all until the Force Barrier was broken by Barry Allen and Wally West, which finally allowed him to escape.[1]

Missing Years

Bart Allen as Impulse, was fighting Mirror Master, when suddenly he was hit by his mirror gun. The gun sent Impulse to another dimension, where his physical form began to disintegrate. When Impulse escaped the dimension, he found that he was in the future. A future where Arrowette, Wonder Girl, Kid Flash, and Robin are dead. When Bart passed out from stress, he awoke in Arkham Asylum with a psychiatrist Harley Quinn. Harley explains that Bart Allen mysteriously disappeared years earlier, and that "it was the Bermuda triangle of superheroes." After Bart escapes Arkham he runs fast and returns home. [2] However when he returns home, due to a mysterious force messing with the universe timeline, ten years of history were removed from existence, but, because Bart was outside of time, his memories of these formerly true events remained with him.

In these ten years, Wally West would have witnessed Barry Allen sacrifice himself to save the Multiverse. Without his mentor, Wally would have filled the role and become the next Flash and would take on Bart Allen as his sidekick.

However, because of the timeline interference, none of these events actually happened, and Bart was the only one who remembered certain people and teams, such as Conner Kent, and Young Justice.

Flash War

While Barry and Wally battled Zoom in the Timestream, Bart attempted to call out for Wally from inside the Speed Force, although Wally was unable to hear him.[1]

Impulse battles Godspeed

Impulse battles Godspeed

Sometime after the Flashes failed to stop Zoom, Bart discovered that the Force Barrier had been broken, allowing him to finally escape the Speed Force.[1]

Bart attempted to seek out the Flash Family members and his old Titans teammates, but couldn't find anyone. He later fought Godspeed and made him retreat.[3]

Young Justice

Bart showed up when Metropolis was invaded by inhabitants of Gemworld and was re-united with Robin and Wonder Girl. With this, Bart claimed that Young Justice was back. Shortly after this, Bart and his friends were pulled into Gemworld and he woke up without them, only to find Conner Kent instead.[4]. After the rest of the team united, they were all confronted by Lord Opal. Impulse stole Opal's piece of Kryptonite, which allowed Conner to defeat Opal. When the team was believed to be sent home, they were banished into the Multiverse, by the council of Gems. While traveling throughout the multiverse, Impulse harassed the residents of all the worlds that they traveled to.

There's something missing here. This section of the article is incomplete, and contains information, but requires more before it can be considered complete. You can help DC Database by editing this page, providing additional information to bring this article to a higher standard of quality.


  • Speed Force Conduit: Bart possesses a connection to the Speed Force, a mysterious cosmic force that pushes time and space itself forward. As a conduit of the Speed Force, all aspects of Bart's physiology are accelerated and enhanced.[1]
    • Superhuman Speed: Bart is capable of moving at incredible superhuman speeds.[1] He was fast enough to hit Godspeed multiple times before he could even react, as well as stay a step ahead of him in a fight.[3] He could have also surpassed the Kryptonian speed as his grandfather did.[2]
    • Superhuman Reflexes: Bart possesses reflexes far greater than a normal human being. This allows him to easily react to danger and events, and perceive the world in slow motion.
    • Superhuman Agility: Bart's agility, balance, and bodily coordination are enhanced to superhuman levels. This allows him to easily maneuver while moving at superhuman speed.[1]
    • Superhuman Strength: The Speed Force enhances Bart's strength to levels greater than any normal human, allowing him to easily carry multiple people while running at super speed.[4]
    • Superhuman Stamina: Bart's body can handle the stress of moving at superhuman speeds for long periods of time without out getting tired or weak.
    • Speed Force Aura: Bart's body is surrounded by a "friction cushion", a field of kinetic absorbent energy that protects him and anyone who is running with or carried by him from the rigorous effects of using his speed. Including friction, airborne particulate matter, heavy impacts, G-Force and the like.
      • Superhuman Durability: Thanks to his protective Speed Force aura, Bart is capable of resisting tremendous kinetic impact forces that could easily crush or kill a human, without suffering any serious external or internal injuries.
    • Accelerated Healing: Like all conduits of the Speed Force, Bart is capable of regenerating from injuries much faster than any normal human. However, Bart has "hyper-metabolism", meaning his body's metabolism is much faster than even that of other speedsters. Side effects of this include accelerating aging, as Bart revealed he had physically looked like a teenager at the age of 2.[2]
      • Toxic Immunity: Bart's hyper-metabolism provides him with a enhanced immunity to toxins. When exposed to a drug that would negate his super speed, Bart's metabolism quickly pushed out the drug and its effects.[2]
    • Dimensional Travel: After the Force Barrier had been broken, Bart was able to use his speed to escape the Speed Force and travel back to Earth.[1]
    • Electrokinesis: As a conduit of the Speed Force, Bart's body generates large amounts of the electrical energy that he draws from the Speed Force. This Speed Force lightning emanates off of him, especially when moving at superhuman speed.[1]
    • Enhanced Senses: The Speed Force grants Bart enhanced senses that allow him to perceive the world at a rate attuned to his reaction speed. He can also mentally tap into the Speed Force at will for various purposes.[5]
      • Cosmic Awareness: Bart learned to use the Speed Force to fill in the gaps of his forgotten memories about the universe. While doing this, Bart learned of the various time shifts, reality bends, and reboots that have occurred within the universe.[5]
    • Molecular Acceleration: Bart can vibrate his own molecular structure at varying degrees for a number of purposes, by adjusting to different frequencies.[2]
      • Intangibility: Bart can vibrate his molecular structure to an intangible state, allowing objects to pass through him.[2]
      • Phasing: By vibrating his molecules on an atomic level, and by doing so at just the right frequency, Bart can phase through objects such as walls without damaging them.[2]
    • Retrocognition: After escaping the Speed Force, Bart stated that the world he had returned to was not the one he had left behind. He remembers the Pre-Flashpoint world, similar to the way Wally West does.[3]
    • Time Travel: By running fast enough, Bart is able to jump into the timestream and travel throughout it, without the aid of a Cosmic Treadmill.[2]
    • Vortex Creations: By rotating his arms at super speed or running in a circular motion, Bart can manipulate the airflow around him to create strong vortexes of wind.[3]


  • Acrobatics: Due to his superhuman agility, Bart is capable of performing acrobatic maneuvers with ease while moving at super speed.[4]
  • Hand-to-Hand Combat (Advanced): Bart is a skilled fighter and has mastered using his super speed to his advantage during combat. Using his powers combined with his fighting skill, Bart was able to easily outmatch Godspeed, to the point of forcing him to retreat.[3]
