In Star Wars: The Clone Wars, Clone Trooper Jesse was killed during the Siege of Mandalore. He was killed by Darth Maul during Order 66, when the clones turned against the Jedi following the secret activation of the inhibitor chips implanted in their brains. Jesse unfortunately did not survive this tragic turn of events.
How did he become an arc tropper
In the Star Wars: The Clone Wars series, Jesse did not become an ARC trooper. He remained a regular clone trooper throughout the series, serving as part of the 501st Legion under the command of Captain Rex. ARC troopers are elite clone troopers who undergo advanced training and possess additional skills and abilities compared to regular clone troopers. While Jesse was a skilled and loyal trooper, he did not undergo the specialized training required to become an ARC trooper.
