Brock Starsher/Legends
Brock Starsher was employed by Jabba the Hutt. He was a guard on the second skiff during the Battle of the Great Pit of Carkoon in 4 ABY, where he was killed by Luke Skywalker and fell into the sarlacc's mouth. He wore the same helmet as Sergeant Doallyn. His weapon of choice was the vibro-ax.
Behind the scenes

Starsher wears the same helmet as Sergeant Doallyn, which led to a long-standing confusion as to whether or not they were the same character. It was generally assumed that the character seen at the entrance to Jabba's throne room was the true Doallyn, as Tales from Jabba's Palace established him to be alive after Jabba's death. The confusion was finally solved with the publication of Star Wars Insider 143, which provided Brock Starsher a distinct name for the first time.
In 2014, Hasbro released an action figure of Brock Starsher in the Black Series 3.75" line. However, the figure was simply labeled as 'Jabba's Skiff Guard' on the packaging.
