Zoom

"Zoom" is a speedster from Earth-2. Jay Garrick describes him as a demon with a "face of death." He is in some way, the product of the Earth-2 Harrison Wells.

Early life
Almost nothing is known of Zoom's history except that he is somehow the product of the Harrison Wells from Earth-2. 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 and went on to become the prime enemy of Flash, killing hundreds of people. Flash spent 2 years of his career tracking Zoom with little success and Zoom in turn became obssessed 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 The 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. Before Zoom could finish off Flash however, a huge portal in the sky opened and The Flash was sucked into it and brought to Earth-1 while Zoom, still on Earth-2, believed The Flash had been eliminated and raced away.

Targeting Flashes
Upon gaining access to 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, according to Jay Garrick, 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 The Flash. Atom-Smasher accepted the offer but was eventually defeated by Barry and his team.

In the wake of Atom-Smasher's defeat, Zoom decided to try again and briefly returned to Earth-2. He then soon came back to Earth-1, this time with the metahuman Eddie Slick/Sand-Demon whom he forcibly brought with him. Zoom then extorted the terrified metahuman by promising to return him to Earth-2 in exchange for killing The Flash. Sand-Demon consented but was defeated by the combined efforts of Barry Allen, his team and Jay Garrick.

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

Some time in spring 2016, Zoom had an encounter with Barry that caused him to miss the funeral of a person close to himself and Oliver Queen.

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 speeds, something neither Barry Allen nor Eobard Thawne have yet demonstrated. While at superspeed, the Speed-Force lightning that radiates off him is sapphire blue as opposed to the normal yellow or red lightning exhibited by previously-seen speedsters like Barry Allen or Eobard Thawne.
 * 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. Similar, he can vibrate his cells fast enough to forcibly expel any toxins that do manage to affect him. His vibrations are more powerful than other speedsters, causing the electricity on his body to constantly show when he is disguising himself.
 * 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 Force absorption: 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 of his speed.

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.

Equipment

 * Speedster-suit: Zoom wears a pitch-black variation of Barry Allen's Flash suit with a black, inverted lightning-bolt on the center-chest and lightning-bolt shaped ear-pieces. The suit does not have a slot on the face that allows the mouth to be seen and limits the view of the eyes. The suit's material composition is currently unknown, though it is clearly made of friction-proof material.
