Chronos (Arrowverse)

Chronos is a temporal bounty hunter who first appeared on the first episode of DC's Legends of Tomorrow. He works for the Time Master Council and is tasked with the mission of bringing Rip Hunter back to the council.

Pilot Part 1
Chronos appears in the episode searching for Rip Hunter and the Wave Rider having only just missed the Wave Rider time jump back into the past. However he gets caught by two civilians thinking he is cosplaying as Darth Vader, Chronos merely looks to his scanner and identifies that they don't make any difference to the timeline so he mercilessly kills both of them.

Later in the episode Chronos has time travelled to 1975 and has found Rip Hunter's ship. Even though the waverider is currently invisible, Chronos can still identify it most likely due to the time distortion that it has caused. Chronos begins shooting at it and soon the ship is in critical condition. Meanwhile Rip Hunter, Stein and Ray Palmer are trying to get to the ship as fast as they can. As Chronos continues to fire on the the Waverider, Hawkgirl comes in to attack Chronos. The two engage in close quarters combat which provides a distraction for Rip's team to take cover. Chronos soon best Hawkgirl but Hawkman comes and uppercuts Chronos. Rip Hunter takes out his own gun and begins to fire at Chronos. The two engage in a gun fight behind cover which provides Martin Stein and Ray Palmer a chance to get back to the ship to become Firestorm and The Atom. Chronos then throws a grenade at Rip Hunter which explodes. He soon approaches Rip and presses a detonator but is interrupted by Captain Cold slamming a car into him. Firestorm and The Atom emerge from the ship and begin firing on Chronos. With everyone attacking him Chronos starts firing wildly and is able to deal a fatal blow to Aldus Boardman. This blow will result in Aldus' death which Hawkgirl was attempting to prevent in the first place. The Legends of Tomorrow escape on the ship to treat Aldus' wound and Chronos is left behind in 1975.

Power and Skills
As a bounty hunter Chronos is extremely adept at both hand to hand combat and ranged combat. He is an excellent marksman almost always hitting his mark, even when his target is invisible. The only times he misses are when he is taking on multiple targets at once. However Chronos himself was able to make the Legends of Tomorrow flee from him. This implies that although they were able to hold him off, Rip Hunter believes that Chronos would be able to defeat the Legends of Tomorrow even as they worked as a team.

Chronos also has some kind of analyser which allows him to see who or what is integral to the timeline. This analyser was most likely what allowed him to see the Waverider in stealth mode. Chronos can also time travel to any part of time.
