Rakaar was a Starfleet veteran, originally from the planet Kazar. Purple-skinned Rakaar had previously served aboard a Constitution-class Federation starship. In 2267, terminally ill, Rakaar helped hijack the USS Enterprise at the command of a fellow Starfleet Veterans' Hospital patient named En-Lai, but Kirk suspected that Rakaar would be granted clemency for the crime. When En-Lai diverted the Enterprise to Calydon, Rakaar's illness was completely healed by the lady of Calydon. (TOS comic: "A Small Matter of Faith")
