- ―Lieutenant Ryler Dorant
In 3643 BBY, Ryler served as Havoc Squad's medic, in which he was primarily focused into synthesizing combat stimulants. He was stationed on Ord Mantell until he decided to join the Sith Empire with his team. Needles eventually traveled to Taris and weaponized the rakghoul plague, make it fast acting, testing it on newly defected Republic troops. The new Havoc Squad managed to stop and kill Needles, ending his experiments. His position in Havoc Squad was later filled by Elara Dorne.
