Zoom

"Look at your hero, this man is no god, he is nothing. The days of The Flash protecting this city are over. Now what will you do without your precious hero?"

- Zoom declaring himself victorious.

"Zoom" is a "speed demon" from Earth-2 and the archenemy of Jay Garrick/The Flash. After the singularity caused by Reverse-Flash's "demise" 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 and began extorting meta-humans from Earth-2 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, Jesse Wells, and is currently holding her hostage. At one point after Wells' departure, he confronted her again demanding to know why Wells had traveled to Earth-1. Jesse professed not to know and Zoom complimented her loyalty before subjecting her to torture.

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.

To find out what Harry knows, Cisco "vibes" him by touching him, and sees Zoom interrogating Jesse. Zoom's metahuman plans took an unexpected turn when he was contacted by the Earth-1 Linda Park posing as her evil Earth-2 counterpart Dr. Light, claiming that she had killed Barry and threw in his emblem as proof in order to lure Zoom into a trap orchestrated by Barry and his team. Zoom however was saw through the deception easily and did not take the bait, choosing instead to bide his time. Once he was sure The Flash and his team had let their guards down, Zoom really did come through the breach and kidnapped Linda, bringing her to the top of the Star Labs building. There he was confronted by Flash, who begged him not to hurt Linda. Zoom scoffed at Flash's request and dropped Linda off the edge of the roof but Flash raced to the bottom and used a wind-funnel to save Linda before turning to face down Zoom head-on. Flash then turned and sped around Star Labs, building up his speed electricity before throwing a lightning bolt at Zoom who, to Flash's horror, jumped into the air, grabbed Flash's lightning bolt and hurled it right back at him with even greater force, scoring a direct hit. In desperation, Flash tried to outsmart Zoom by forcing him into a freefall from high up in the air but Zoom reversed the move and landed on top of Flash. Zoom then proceeded to brutally and mercilessly pulverize Flash at high speed before ending with a devastating blow to Flash's spine, effectively paralyzing him. Wells attempted to sneak up on Zoom and shoot him with a speed dampening dart but Zoom caught the missile and instead jammed it, along with Flash's, into Flash's chest while declaring to Wells that he was next.

Victorious, Zoom dragged Flash's limp and battered body across Central City at superspeed to the newspaper and the police to showcase his triumph, declaring that the days of Flash were over. Finally, Zoom returned to Star Labs with Barry in his hand to confront Wells and the team, Zoom bade farewell to Barry before draining him of his speed. Drunk with victory and in the midst of gloating to Wells, Cisco managed to shoot Zoom in the neck with a dart filled with the speed dampening serum. Bellowing in agony, Zoom temporarily collapsed on the floor before racing away.

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. Finally, he carried Barry's body back to STAR Labs, showcasing him to Caitlin, Cisco and Harry (Harrison Wells Earth-2).

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

He has also clearly been shown to be psychotic, as he shows absolutely no remorse or regret in his use of other people, metahumans or otherwise, treating them as disposable pawns to further his goals. His manic personality is a reflection of his obsession with speed, and possibly an effect of his tremendous powers on his cognitive faculties.

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 near-light speed. While running, the speed-force noise that he emits has a very pronounced thunderous yet strangely sharp and high-pitched quality. Unlike previously seen speedsters like Barry Allen, Jay Garrick or Eobard Thawne, the Speed-Force lightning that radiates off Zoom is sapphire blue as opposed to yellow (Barry and Jay) or red (Eobard).
 * Superhuman reflexes: Because of Zoom's immense speed, his reaction time is augmented, allowing him to react to danger and events far faster than a normal human. He easily saw and countered a bolt of lightning hurled at him by Barry and likewise caught every single bullet launched at him by the entire police force with ease.
 * Superhuman durability: Zoom has the ability to have large amounts of damage inflicted on him, and be hurt at a rate lower than regular humans, sometimes suffering no injuries. During his fight with Barry, he fell to the ground from hundreds of meters in the air with no noticeable injuries, and quickly resumed viciously pummeling Barry.
 * 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. It's unknown as of yet what he really sounds like without using his powers to change 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: As a speedster, Zoom can produce powerful electricity from his body, that always emanates off of him, whether he is moving at super speed or not. He could also manipulate this electricity by touching it, as when Barry tried hurling lightning at Zoom, he managed to grab and hold the lightning as if it were a tangible object and hurl it back at him.
 * Interdimensional travel: Zoom is able to travel between Earth-1 and Earth-2 at will. He does so by using the "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 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.
 * Extreme force generation: Zoom is capable of inflicting massive amounts of physical damage on his opponents by packing speed into his blows. He was able to reduce Barry Allen/The Flash to a bloody mess in seconds with his deadly strikes, and even break his spine, causing paralysis. Even with Barry's rapid healing, the damage inflicted on him was noticeably prolonged.
 * Enhanced strength: Presumably due to his great amount of Speed Force energy, Zoom showed the ability to effortlessly exert great strength and force, enough to lift fully grown humans over his head with only one arm, without any strain or effort. Combined with his efficient fighting skills, Zoom is able to deal severe bodily harm with only a few blows.
 * Rapid cellular regeneration: Zoom's powers also afford him a heightened healing capacities. This is caused by his body's molecules moving at accelerated rates, causing the chemical reactions responsible for metabolism to mend and even restore any damages much quicker and efficiently than regular humans. Despite being shot by Cisco Ramon with a serum to dampen his speed, Zoom almost instantly recovered and ran off, showing no signs of having been slowed down by the serum.
 * Accelerated Perception: Zoom is easily capable of keeping up with and clearly perceiving the movements of other speedsters while they are at superspeed themselves even when he himself is not. He was able to carefully and methodically track Barry Allen's exact movements during Barry's efforts to build up electricity for his Speed-Force lightning attack outside Star Labs

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 meta-humans, 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, even adjusting the strategy based on knowledge on Barry's personal life he somehow attained. 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 every way, leaving Barry near death, a testament to his strategic fighting and planning.
 * Intimidation: Due to his incredible power and demon-like appearance, Zoom commands an extremely intimidating presence, able to instill terror in the most powerful of metahumans, even in Jay Garrick. Nearly all of the metahumans from Earth-2 fearfully 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.
 * Hand-to-hand combatant: Complementing his ferocious appearance and personality, Zoom's unpredictable yet efficient style uses his tremendous speed and powers. His style is more precise than Barry Allen's yet not quite as tactical as Eobard Thawne's. Instead, Zoom uses powerful punches to accompanied by his claws for savage slashing movements, overall causing great blunt-force trauma. He also uses his great reflexes to redirect attacks from his opponent.
 * Acrobatics: Zoom showed the capability to flip in midair when throwing the Flash's lighting back at him, as well as fight confidently while free falling.

Weaknesses

 * Speed dampening serum: When Zoom was about to kill Barry, Cisco used his powers and was able to shoot him with a dart containing a speed dampening serum, which was shown to work somewhat. However, his healing capacities slowed the serum down to allow Zoom to run away before the serum took full effect in order to avoid being captured.

Equipment

 * Zoom suit: He wears a protective suit as his supervillain alter-ego, Zoom, to hide his true identity from his victims. It is unknown what materials it's made out of. Zoom's suit is unique in that unlike Barry who wears a mask that just covers half his face, Zoom has his whole face covered with only slits for a mouth that give him a somewhat demonic appearance, and gloves that end in pointed claws that he uses in combat. The suit itself is pitch black and boasts an inverted lightning-bolt shaped crest and lightning-bolt shaped earpieces.

Trivia
