“Star Wars: Resistance” was a short-lived animated series that aired from 2018 to 2020 (via IMDb). The series chronicled the days of the Resistance before Star Wars: The Force Awakens, with most of the action revolving around a young pilot named Kazuda Xioni (Christopher Sean).
Elijah Wood voiced Jace Rucklin, a human racer who ended up on the wrong side of the track. He and Kazuda knew each other from before, but eventually found themselves on opposite sides of the war. Unlike Frodo, Jace was an arrogant and deceitful character who held a grudge, and his piloting skills led to his being recruited by the First Order as a TIE fighter pilot.
Of course, it’s possible that Jace was simply misunderstood. During an interview with the Star Wars YouTube channel, Wood described the experience as a lot of “fun,” but he insisted Jace wasn’t a villain. “He just wants to be better than everyone else,” noted Wood.
