Savitar

"Savitar" is a speedster with a metallic appearance, affiliated with Dr. Alchemy, dubbing himself the "God of Speed".

Biography
After the Rival failed, Alchemy scolded him and then Savitar entered his cell at Iron Heights in the meta-human wing and attacked him. He was able to enter despite the cell being a meta-human power dampener and use his powers fully. Upon investigation, Barry, Joe and Julian discovered that Savitar killed the Rival the night he was incarcerated, but could only see him as a flying ball of light.

In an effort to lure Alchemy into a trap, Team Flash and a CCPD strike team followed secretly behind Wally West as he approached Alchemy about his visions of Flashpoint. Wally stalled Alchemy long enough for the police and Team Flash to storm the hideout and Alchemy and his cohorts were surrounded and shackled. Flash triumphantly stood before Alchemy and went to unmask him. Just as he was about to do so, an earthquake shook the hideout and suddenly a small blip of light began racing around the hideout, killing all of the cops and freeing Alchemy's followers, at which point Flash realized that it was a speedster. The being was pursued by the Flash, but its speed was far beyond his and eventually Barry was brought down instead. As Wally West was trapped in a cocoon-like container, the mysterious speedster pinned a distracted Flash to a wall, though when Joe looked at them, Savitar was invisible to him. As the Flash finally beheld his armoured foe, he asked him who he was, to which the speedster replied that his name was Savitar, the "god of speed." Savitar then produced a blade from his gauntlet and prepared to finish off the Flash.

Powers

 * Superhuman speed: Though it is unknown the nature of his speed, Savitar is unfathomably fast, so much so that he's totally invisible to the human eye while running. His stupefying speed appears to outpace all other speedsters who came before him. His speed allowed him to race around Alchemy's lair and instantly kill multiple cops in milliseconds. Only Barry was able to see anything. Barry was at a loss to keep up wit him. He was also able to get into Edward Clariss's prison cell, despite his cell containing a meta-human power dampener, and to fully use his powers once inside.
 * Superhuman agility: Savitar possesses inhuman bodily coordination, balance, equilibrium, and dexterity. He is able to change direction immediately, thus allows him to make sharp turns and easily manuever while moving at immense speed.
 * Electrokinesis: While moving, he emanates a blue-white lightning, which to normal humans, he can't be seen.
 * Geokinesis: Savitar seemingly can create earthquakes with his speed, as he caused a powerful tremor when he arrived at Alchemy's lair.
 * Invisibility: Savitar is so fast that only other speedsters can see him while he's running at super speed, while non-speedsters are not able to see him at all.
 * Superhuman stamina: Savitar's body can handle the stresses of superhuman racing without noticeable distress.
 * Superhuman momentum: Savitar can generate great amounts of physical force through the kinetic energy his immense speed generates.
 * Superhuman strength: Savitar possesses a level of increased strength, able to lift a full-grown man off the ground, holding them up by their throats, and pinning them to walls, all with a single hand.

Equipment

 * Armor: Savitar wears some form of armor, though it's unknown if it is something he's actually wearing or if he is made out of it. The armor is also able to produce a blade from it's left gauntlet.

Trivia

 * Since he generates electricity while running, he most likely gets his powers from the Speed Force.

Behind the scenes

 * In DC Comics, Savitar was an enemy of Wally West as the Flash, an ex-pilot obsessed with speed, who named himself after Savitr, the Hindu "god of motion", and dedicated his life to unlocking the secrets of the Speed Force. He made creative ways of using the Speed Force and tried to kill every other speedster on Earth, transferring their Speed Force connections onto himself.
