Zoom

"Never forget, I am the fastest man alive."

- Enter Zoom

"Zoom" is a speedster from Earth-2 and the archenemy of Jay Garrick/The Flash. After the singularity caused by Reverse-Flash's "death" on Earth-1 opened in Earth-2, Zoom traveled to Earth-1. After arriving he learned of the existence of Barry Allen/The Flash and came to despise him too, and now extorts metahumans from Earth-2 stuck on Earth-1 into killing Barry in exchange for a way home.

Early life
Almost nothing is known of Zoom's history except that he was supposedly affected by Earth-2 Harrison Wells' particle-accelerator when it exploded underground, which is what gave him his powers. No one knows what he really looks like or even what his real name is, but what is known is he first appeared on the Earth-2 radar around the same time that Jay Garrick/The Flash acquired his Speed-Force powers, rampaging around Central City and killing hundreds of people. The Flash spent the next 2 years of his career tracking Zoom with little success and Zoom in turn became obsessed with destroying The Flash, desiring to be the only speedster in any world.

One night, the two had their biggest battle yet, where they raced throughout Central City as Flash fought hard to keep up with his incredibly fast demonic foe. Eventually, Zoom gained the upper-hand atop a tall skyscraper and began phasing his hand through the Flash, somehow managing to drain Flash of his speed. Before Zoom could finish off Flash however, a huge portal in the sky opened and Flash was sucked into it and brought to Earth-1 while Zoom, still on Earth-2, believed Flash had been eliminated and raced away.

At some point during his reign of terror on Earth-2, he kidnapped Earth-2 Harrison Wells' daughter, and is currently holding her hostage.

Targeting the Flash
Upon gaining access to Earth-1 through his advanced Speed powers and the interdimensional breaches, Zoom learned of the existence of Barry Allen/The Flash and grew to despise him too for having speed powers also and vowed to kill him as he desires to be the only speedster in any world. Through his efforts, Zoom came into contact with Al Rothstein/Atom-Smasher from his world, who'd also come through one of the breaches, and offered him the chance to return home if he killed Flash. Atom-Smasher accepted the offer but was eventually defeated by Flash and his team.

In the wake of Atom-Smasher's defeat, Zoom decided to try again and briefly returned to Earth-2 to retrieve the metahuman Eddie Slick/Sand-Demon, and forcibly brought with him to Earth-1. Zoom extorted the terrified metahuman by promising to return him to Earth-2 in exchange for killing Flash. Slick consented but was defeated by the combined efforts of both Flashes.

Undaunted by yet another failure, Zoom enlisted the services of another meta-human, King Shark. Unfortunately for Zoom, he was defeated by Harrison Wells of Earth-2.

Following his failures Zoom adjusted his strategy. Somehow gathering details about Barry's personal life including his previous romantic attachment to Central City sports-reporter Linda Park. Zoom then sought out her Earth-2 counterpart Linda Park/Dr. Light and brought her to Earth-1 and forced her to seek out and kill The Flash, even though Earth-2 Linda was just a small-time thief and had never taken a life before. Zoom believed that Flash would be unable and/or unwilling to use lethal force against her due to his previous attachment to her Earth-1 counterpart. His plan was however thwarted once more by Barry Allen and his team with guidance from the Earth-2 Harrison Wells and resulted in Dr. Light's capture and imprisonment in the Pipeline. Zoom later visited Wells' daughter and told her that her father had abandoned her but she stood her ground, saying that he would find her and kill Zoom. However Zoom scoffed at the idea and reminded her that the fates of her and her father were still in debate and sped off.

Some time in 2016, Zoom had an encounter with Flash that caused him to miss the funeral of a person significant to Oliver Queen.

Personality
Zoom is obsessed with speed to the point of being unstable, as noted by his creator, he has set a mission of eradicating anything else with super speed, enthralling meta-humans to go out and kill speedsters, namely Barry Allen at the moment. According to Earth-2 Harrison Wells, those under the enthrallment of Zoom are bound to do things out of character, such as turning a thief into a killer. Zoom instills a tremendous amount of terror in almost everyone he encounters, including Jay Garrick himself who describes Zoom as being a "demon with a face of death". Jay even admits he didn't confront Zoom sometimes when he should have out of fear.

Zoom has been shown to be extremely egotistical, as after his victory against The Flash in the episode, "Enter Zoom," he proceeded to parade Flash's body to Central City News, where he displayed it to the media like a hunting trophy, proclaiming himself to be "The fastest man alive." He then hauled the unconscious Flash to the Central City Police Department, gloating to the assembled officers, and reveling in their helplessness as he caught dozens of bullets with his speed.

Zoom is also horribly sadistic, enjoying the fear and terror in his helpless prey with obvious and somewhat animalistic satisfaction.

Powers

 * Superhuman speed: Zoom can move unimaginably fast and might be the fastest speedster in all of existence according to Jay Garrick, who himself, is capable of moving at the speed of light. While running at superspeed, the speed-force noise that he emits has a very pronounced thunderous and concussive quality akin to that of a storm. When Barry tried hurling lightning at Zoom, he managed to move at a speed that permitted him to grab the lightning and hurl it back at him. He proceeded to dragging Barry all over Central City at incredible speed and was easily able to catch every bullet fired at him with one hand when he went to the police station.
 * Bodily vibration: Zoom has the ability to vibrate some or all of his cells and overall parts of his body on command for various effects. His bodily control can vibrate his entire body to mask his form from others clearly perceiving it and distort his vocal cords to disguise his voice. His vibrations are more powerful than other speedsters, causing the electricity on his body to constantly show when he is disguising himself.
 * Electrokinesis: Like all speedsters, Zoom generates a powerful electricity from his body and can use it in any way he chooses. While using his super-speed, the electricity that radiates off him is sapphire blue as opposed to the normal yellow or red exhibited by previously-seen speedsters like Barry, Jay or Eobard. He has even been shown to grab and redirect lightning bolts hurled at him, such as his first fight with Barry, during which he snatched a bolt of electricity and threw it back like a javelin.
 * Interdimensional travel: Zoom is able to travel between Earth-1 and Earth-2 at will. He does so by using the so-called breaches between worlds; his stupendous speed allowing him to temporarily stabilize the interdimensional 'corridors' that link any one breach on Earth-2 with a corresponding breach on Earth-1, letting him and those he brings along pass through them.
 * Speed steal: Zoom can absorb the speed of other speedsters, further amplifying his own speed. He appears to do this by stabbing another speedster with his claws and draining the power from their body, as shown when he sapped Jay Garrick and Barry Allen of his speed. The more speed he absorbs, the more powerful he gets, and Earth-2 Harrison Wells is concerned that if Barry doesn't fight Zoom soon, he will not be able to stop him.

Abilities

 * High-Level intellect/Master tactician/Manipulator: According to Jay Garrick, Zoom is extremely intelligent. He outsmarted Jay, who possesses an equally sharp mind, multiple times for over 2 years and the latter claims that he always seems to be one step ahead. Zoom is also able to manipulate powerful metahumans, either through simple bargaining or fear-extortion, such as Atom Smasher or Sand Demon to do his bidding, under the promise of returning them to their world afterwards. Zoom managed to evade the trap that the Flash and Harrison Wells from Earth-2 had set to capture Zoom. Zoom was able to easily out maneuver and out-fight Barry in everyway, leaving Barry near death, a testament to his strategic fighting and planning.
 * Intimidation: Due to his incredible power and demon-like appearance, Zoom possesses a very intimidating presence, able to cause terror in the most powerful metahumans and even in Jay Garrick. Nearly all of the metahumans from Earth-2 speak of Zoom as a monster or demon, and consider him unbeatable, like when Atom Smasher considered Central City from Earth-1 and Barry Allen "unworthy" of him.
 * Fighting Skills: Complementing his ferocious appearance, Zoom's combat style utilizes his obvious speed and powers, while accenting it with his almost feral personality. His combat style is not as raw and unrefined as Barry's, who tends to use basic punches and kicks, yet not as neat and efficient as Eobard's, which emphasizes attacking vital points to overwhelm his opponents with minimal effort. Instead, Zoom uses his claws for savage slashing movements meant to tear apart his opponents like a beast, and uses his electrical powers to redirect attacks from the likes of Barry and, presumably, Jay Garrick.
