Chronos is a supervillain who commits time-based crimes. Chronos became fixated with Batman and collected as much information as he could. Chronos came to the realization that the night Batman took down Carmine Falcone was an opportunity to kill him. One night, he broke into a Wayne Enterprises facility and stole an exotic power source. He fled the scene in an O Wheel Car with Batman and Blue Beetle in hot pursuit. He had no idea who Blue Beetle was. As the chase led to the docks, Chronos weaved around people and fired his Time Bombs to stop them in place and stall Batman. Chronos returned to his hideout in a rundown apartment building and quickly charged his Time Glove with the stolen energy. By the time Batman and Beetle arrived, they were too late. To make matters worse, Beetle impulsively fired his arm cannon and caused a small cave-in. Chronos activated his glove and generated a Time Portal to the past. Chronos entered the Falcone Family Warehouse and tried to warn Falcone that Batman would be coming for him.
Falcone was naturally skeptical but took precautions. Chronos watched from the rafters above. Batman and Beetle made sure not to run into anyone or risk creating a paradox and confronted Chronos. Blue Beetle was irritated with not being recognized and attacked. As a result, Chronos dropped his Time Bombs down below - creating a pocket in incredibly slowed down time. Chronos decided to assassinate Batman himself and hit an emergency release button. A crate nearly fell on the younger Batman but Batman tackled it away. Chronos jumped to a rope and fell on come crates then grabbed a piece of wood. He rushed the younger Batman but was shoved. He activated integrated hardware in his mask with the Time Glove and peered one second into the future. He was able to see Batman's next move before he made it and plan a suitable counter move. Eventually, Batman threw down some smoke bombs and circumvented Chronos' ability. He easily creeped up on Chronos and punched him out. Once it was certain the timeline was preserved, Batman and Beetle returned to the present with Chronos. He was turned over to the Gotham City Police Department. Batman, in a rare instance, told Beetle he did a good job.
