Savitar's History
Created by Barry Allen/The Flash to battle Savitar after the creation of Flashpoint, Barry's time remnants were all killed by the armored villain, except for one. This remaining remnant, shunned by Team Flash due to not being their Barry despite knowing everything that he does and feeling everything that he once felt, was left broken and alone until he decided to take revenge on "the real Barry" by any means necessary. To this end, he created his own futuristic armor and became Savitar, the very villain that indirectly created himself. After several battles with Barry, Savitar was imprisoned in the Speed Force by Tracy Brand, a scientist who developed a "Speed Force bazooka". However, before his imprisonment, Savitar manages to split up Team Flash and kill Iris West, thus making him a more personal foe to Barry than some of his other foes.
Savitar returns to Central City in 2016 to take revenge on Barry and the entire Team Flash, whom he holds responsible for his banishment. Savitar also intends to stop Barry before he can imprison him in the future, while also recreating the circumstances that led to his creation. As his imprisonment prevents him from arriving on Earth-1 in the flesh, Savitar uses the Philosopher's Stone, to which he is bound, to take control over Julian Albert, creating the split personality Alchemy in the man.
Through Albert, Savitar sets in motion an elaborate plan to escape the Speed Force. After Barry Allen, the Flash, has reset the Flashpoint timeline, Savitar starts handing meta-human powers to those who had it during Flashpoint. One of the recipients is Wally West who, by taking Savitar's gift, creates a special connection to Savitar.
Although Albert is eventually cured, severing Savitar from his proxy and thus his influence on Earth, Savitar starts appearing to Wally through the connection between the two. Furthermore, Barry and his team manage to contact Savitar in the Speed Force using Julian as a medium. From Savitar, they learn that he deeply despises all of them for what they will do to him in the future. He makes a prophecy regarding the fate of the team, claiming that in the events that lead up to the future creation of Savitar and Savitar's imprisonment, one team member will betray the team, one will fall, one will suffer a fate worse than death. In addition to Savitar's prophecy, Barry has to fight off the impending danger of Iris West's death, because he saw Savitar murder her when he accidentally raced to the future.
From his Speed Force banishment, Savitar uses Wally's youth and ego to his own advantage, eventually manipulating the young Wally into opening a breach into the Speed Force under the pretext to throw the Philosopher's Stone into it. Although Wally believes that this prevents Savitar from returning, it in truth gives Savitar everything he needs to leave the Speed Force. Savitar emerges on Earth-1 and, in return, Wally is dragged into the Speed Force to take Savitar's place. Free at last, Savitar is now able to shape the events to lead to the future he foresaw, including the death of Iris and Savitar's creation. He claims to have big plans for Jesse Quick and has managed to convince Killer Frost to side with him. After Barry figures out who Savitar is, he confronts him, thus leading to Savitar taking his armor off and explaining who he is and how he came to be.
Eventually, the time came that he would kill Iris in front of Barry; however, he discovers that he actually killed H.R. (Earth-19 Harrison Wells) using light-refraction technology to disguise himself. Knowing that he would be erased from existence any minute, he initiated his plan to spread himself across time and rule the world as a god. After a battle with Barry, Wally and Jay, Savitar's armor is destroyed. Just as he is defeated, Savitar runs at Barry, ready to kill him, only to be shot in the back by Iris, killing him and allowing the paradox to erase him from existence.
