Ekelarc was a Y-Wing pilot for the Rebel Alliance, and fought in the Battle Of Endor. His designation was Grey Four. He was a big Batman fan. He dressed up as the Joker for the Rebel Halloween party, but was frustrated because several other members chose the same costume. They didn't even like Batman that much, and their costumes weren't nearly as accurate as his.
Ekelarc is sometimes called Harb Nafgan. By jerks.
