Savitar

"You may serve the Speed Force, Flash, but I rule it. You are only a man, but I am a god. Your god. I am Savitar!"

- Savitar to the Flash

"Savitar" is an ancient and unimaginably powerful speedster with a metallic appearance, dubbing himself as the "God of Speed". He was also called the Dark Lord by an Acolyte of his cult, which he led himself through an avatar known as Alchemy, preparing worlds for his arrival. According to stories and myths learned by Jay Garrick, he was the first meta-human speedster in the multiverse.

Early life
According to Julian Albert and Jay Garrick, "Savitar" was the first ever speedster and the fastest of them all. He appeared to have been a normal man once before using the Philosopher's Stone that transformed him into a metallic creature, named after the Hindu god of motion. He dubbed himself the "God of Speed" and founded a cult. Over the centuries, Savitar travelled throughout the multiverse with the Philosopher's Stone in hand, seeking out the most powerful Speedsters who threatened his power to battle and then taking over their Earths. Before each encounter, he would possess a person and use them as a medium under the alias "Alchemy" to 'prepare' for his arrival by having "Alchemy" create metahuman armies for Savitar to command.

At one point Savitar was somehow defeated by a future Barry Allen, who somehow used his connection to the Philosopher's Stone to trap him "for an eternity" within a special box, to which Savitar swore revenge. After Barry undid Flashpoint, Savitar became aware of the Speedster's rising power and takes control of Julian Albert using him as the next Alchemy, and proceeds to restore powers to individuals that had abilities in the alternate timeline to "prepare the world" for his return.

Slaying his pawns
After the Rival failed to kill the Flash, Savitar scolded him and proceeded to enter 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, although they could only see him as a flying ball of light.

Savitar revealed
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 to allow the police and Team Flash to storm the hideout. Alchemy and his cohorts were subsequently 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. Realizing the blip of light was a speedster The Flash attempted to pursue it but it's speed was far beyond his, and Barry was brought down instead. As Wally West became trapped in a cocoon-like container, the mysterious speedster pinned a distracted Flash to a wall, though when Joe looked at them he could only see Barry. The new speedster was invisible to him. Finally able to see the enemy speedster, the Flash saw it as a heavily armored, very tall, robotic looking person, identifying itself as Savitar, the god of speed. Savitar then produced a long curved blade from his gauntlet and prepared to finish off the Flash.

Luckily, the Flash was saved at the last second by the timely intervention of Joe West who managed to shake off his attackers and opened fire on Savitar even though he couldn't actually see the speedster. The bullets however deflected harmlessly off Savitar. Ignoring the interruption, Savitar raced out of the lair with the Flash in hand and proceeded to drag, pummel and throw him all across Central City like a rag-doll by somehow using his speed to open up dimensional breaches to various locations around Central City, finally coming to a stop at the waterfront, whereupon Savitar began to savagely beat down his quarry. As the Flash lay broken and bleeding at his feet, Savitar declared the Flash to be beneath him and announced that he (Savitar) was the future while the Flash was the past. Having said this, he grabbed the Flash by the throat and prepared to once again skewer the speedster with his gauntlet-blade. Before he could do so however, the Flash was saved by the sudden arrival of Vibe and Caitlin Snow, who used her ice-powers to freeze Savitar in place and reveal him at the same time but inadvertently harming the Flash too. The ice, though, did not last long and Savitar soon burst out of his ice-prison and sped off.

Looking to reform his power-base, Savitar sought out his most loyal disciple Julian Albert, Earth One's Alchemy, and asked him to reaffirm his dedication to ensuring Savitar's successful return.

Battling the Flashes
With Julian once again mind controlled into taking on the Alchemy persona, Savitar prepared once again to target the Flash. He ordered Alchemy to use a specially-designed building in Central City to refract the energies from the Philosopher's Stone and bestow powers on all the meta-humans in Central City from the Flashpoint timeline at once. Their efforts were interrupted once again by the arrival of two Flashes; Barry having joined forces with the Earth Three veteran speedster Jay Garrick. Before they could do anything to Alchemy, Savitar appeared out of nowhere. While Barry dealt with Alchemy, Garrick squared off against Savitar but was completely outmatched by the metallic speedster, who viciously pummeled, threw around and beat down the elder speedster all across Central City, until finally coming to a stop in an alley. Savitar angrily told Garrick that this was not his fight and unsheathed his gauntlet blade to kill him. Garrick was saved however when Barry sealed the Philosopher's Stone back in its chest, causing Savitar to disappear into thin air.

Looking for a way back to resume the fight, Savitar bided his time while using his telepathic powers to manipulate Cisco Ramon. He used a mental projection of his dead brother Dante in order to convince him that the Stone could help him get Dante back. Entranced by the stone's power, Cisco opened the chest, releasing Savitar once again just as the Flash arrived in Cisco's lab. Savitar then seized the Flash and took him to the Star Labs speed lab whereupon he began to mercilessly beat up the Flash yet again. As he did so, he was stalled by the sudden arrival of the new speedster Wally West who went to attack him but was merely seized by the throat by the metallic speedster and thrown across the room into Barry. As the two speedsters lay defeated on the ground, Savitar unsheathed both of his wrist blades and moved to kill them both. He was however prevented from doing so at the last second when Caitlin Snow convinced Cisco to accept his brother's death and close the chest containing the Stone, sealing Savitar away again.

Fuming from his latest defeat and Alchemy's constant failures, Savitar suddenly felt Julian's consciousness connected to the Stone, established a psychic connection through him and found himself face-to-face with Team Flash. He berated them for not bowing to him, only to be derided for his claims to be a god. Seeking to rattle them, Savitar revealed intimate knowledge of each of the Team Flash members as well as a chilling warning about their future; one would betray them, one would die and one would suffer a fate worse than death. The Flash demanded to know who Savitar really was and what he wanted to which Savitar responded that he wanted to take back everything that the Flash had taken from him before he would destroy him. Confused, Barry angrily asked why Savitar didn't follow through with his threats right away before realizing that without the Stone, he literally couldn't. Enraged, Savitar revealed the reason for his vendetta; that it was in fact a future version of Barry who had trapped him "in eternity" and vowed that he would rise again and the whole world would feel his wrath. Disconcerted, Barry disconnected Julian from Savitar.

Possible future
In one potential future of May 2017, Savitar somehow breaks free from his prison and returns and kills Iris West in front of Barry, declaring to the Scarlet Speedster that he "lost".

Personality
The spitting image of an ego-maniac with a God complex, Savitar believes himself to be a god in every sense of the term. He claims to 'rule' the Speed Force instead of 'serving it' like Barry does and as such he looks down on all others including fellow speedsters with contempt and derision. He believes that he is meant to be worshiped and bowed to by all and has a loyal cult following that he seems to appreciate enough to aid in times of need.

Savitar is merciless and cruel toward his opponents as evidenced by his murder of the CCPD officers in his lair, his savage beat-down of the Flash all across Central City and his willingness to kill the Flash without a second's hesitation.

Savitar has a short temper and is obsessed with revenge on the Flash for imprisoning him.

Powers

 * Speed Force connection/Meta-human physiology: Due to the Philosopher's Stone, he went through a metamorphosis and gained superhuman abilities of inconceivable power. Savitar possesses a extraordinarily potent connection to the Speed Force and his control and power in its usage vastly exceeds all other known users to the point that his potency made him claim to be a god and the "ruler" of it. Even within Edward Clariss's prison cell with a meta-human power dampener, he could fully use his powers.
 * Accelerated healing factor: Savitar's powers of recovery are so strong that even after being frozen solid by Caitlin Snow, he showed no signs of slowing down. Even more, Savitar's healing powers keep him so vitalized, he also appears to be granted immense longevity, if not agelessness, having seemingly been around since ancient times.
 * Bodily vibration: He can vibrate his body at such rates that he becomes totally invisible to normal human eyes. When Savitar was encased in sub-zero ice, he was able to almost instantly break free from his confinement.
 * Electrokinesis: While moving, he emanates white lightning.
 * Possession: With his connection to the Philosopher's Stone, Savitar is able to manipulate others minds. He can telepathically communicate with them and project illusions that only they can see. Once establishing a strong enough connection to the person's mind, he is able to completely overshadow their actions, turning them into his unwitting pawn, as he did with Julian Albert to turn him into "Alchemy", and enabling them to wield the power of the Philosopher's Stone. This power can still be used even while sealed away in the box. However, it is considerably weakened, as he can only prey on a person's insecurities, such as creating illusions of their lost loved ones, to con them into releasing him.
 * 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 maneuver while moving at immense speed.
 * Superhuman reflexes: Savitar possesses superhuman reflexes, allowing him to easily react to other speedsters.
 * Superhuman speed: Savitar is unfathomably fast, greatly belying his massive size and built. His speed allowed him to race around Alchemy's lair and instantly kill multiple cops in milliseconds. Only other speedsters can see anything. Despite Barry's own speed exceeding his other speedster enemies, his own movements were still slow-motion in comparison to Savitar, who effortlessly countered and outmaneuvered the Flash. He later showed equal dominance against the veteran speedster Jay Garrick and simultaneously against Barry and Wally. Despite his seemingly unmatched power, Savitar was somehow defeated by a future Barry Allen and sealed away.
 * Dimensional travel: Savitar's speed is so intense, with a sudden movement he can open breaches, enabling him to shift and warp about and appear out of nowhere. Combined with his raw speed, the actions can appear as if he is at multiple places at once. He is also able to use this power to travel throughout the Multiverse. This is shown by the fact that he knows Jay Garrick.
 * Geokinesis: Savitar is somehow capable of generating earthquakes with his speed.
 * Superhuman momentum: Savitar can generate great amounts of physical force through the kinetic energy his immense speed generates. This allowed him to knock several cops into the air when running past and killing them when he first encountered Barry.
 * Superhuman perceptions: Savitar is easily capable of keeping up with and perceiving the movements and actions of speedsters.
 * Superhuman stamina: Savitar's body can handle the stresses of superhuman racing without noticeable distress.
 * Superhuman strength: Savitar possesses a level of increased strength, able to lift and drag a fully-grown man off the ground by their throat, all with a single hand. He was able to pummel and toss around the Flash, Wally West and Jay Garrick with one hand and, with one punch, he was able to send Jay Garrick flying over a building.

Abilities

 * Master manipulator: In his avatar as Alchemy, Savitar convinced Edward Clariss and other reborn meta-humans to become agents of his will. He was also able to advice and keep in line the rebellious Magenta. As Alchemy, he spoke to his cult members, leading them together to believe that he is a deity. Savitar himself manipulated Julian Albert and later Cisco Ramon to release him, using their own feelings against them.
 * Skilled hand-to-hand combatant: Savitar is a capable fighter as evidenced by his rapid victory over other speedsters like the Flash. His style is not as refined as Eobard Thawne's but is as savage as Zoom's; he uses his extraordinary speed to land powerful blows and throw his opponents around with lots of momentum.

Weaknesses

 * Extreme cold: Much like other speedsters, Savitar seems to be weakened or at least momentarily stunned when exposed to an extremely cold environment. This was proven when Caitlin Snow used her metahuman freezing powers on an invisible Savitar. However, his powers allowed him to shortly afterwards break free and recover enough to zip away.
 * Connection to the Philosopher's Stone: At some point, Savitar was defeated by the future Barry Allen and sealed away. Savitar can only maintain his presence in the world while the Philosopher's Stone is in contact with the world outside of its containment vessel.

Former equipment

 * Philosopher's Stone: Savitar himself possessed this artifact long ago, using it to hire new meta-humans. It is also the source of his power. He used this artifact until being defeated and trapped in it by a future Barry Allen.

Trivia

 * Savitar is the first speedster to be able to move so fast that he becomes invisible, though how he accomplishes this feat is still unknown. This in an ability in the comics, where conduits of the speed-force can move so fast that they are invisible to normal humans.
 * Savitar is the only speedster that generates white lightning, as opposed to yellow (Barry, Jay, Jesse, and Wally), red (Eobard and Edward) or blue (Hunter and Eliza).
 * Savitar is the only speedster so far who has demonstrated the ability to open dimensional breaches to different locations on the same Earth.
 * Despite his apparent and pathological drive to confront the most powerful speedsters who threaten his power-base, Savitar has never crossed paths with speedsters like Zoom or the Reverse-Flash.

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 discovered creative ways of using the Speed Force and tried to kill every other speedster on Earth, transferring their Speed Force connections onto himself.
 * Similarly to how it's depicted in The Flash TV series, Savitar was able to use the Speed Force to make himself invisible to non-speedsters in the comics.
