Boolio was a minor character from Star Wars Episode IX: The Rise of Skywalker. He was a male Ovissian who worked as a miner on the Sinta Glacier Colony. He was voiced by Mark Hamill, best known for portraying Luke Skywalker throughout the Star Wars franchise, who was credited under the pseudonym Patrick Williams.
During the war between the First Order and the Resistance, Boolio aided the Resistance by providing them information. In 35 ABY, he had recieved a data-packet from an anonymous source concerning the return of the former Emperor, Darth Sidious. After authenticating the message, Boolio contacted the Resistance, requesting that they send someone to pick up the datafile as it was too sensitive to risk transmitting. Poe Dameron and Finn later arrived aboard the Millennium Falcon to retrieve the packet and Boolio informed them that it had been sent from a spy inside the First Order, though he didn't know the spy's identity. When Finn asked Boolio how he wished to be repaid, Boolio simply said "Win the war."
Death[]
Despite his precautions, Boolio was discovered by the First Order and was executed for treachery. When Kylo Ren met with his command staff aboard his Star Destroyer, he placed Boolio's severed head on the meeting table as a means of intimidating the spy whom he suspected was one of the commanders.
