She was killed on the Bridge by one of V'ger's probes, but her appearance was later given to another V'ger probe, which was put aboard theEnterpriseand assigned to learn about the human "infestation". However, this "Ilia probe" was constructed so perfectly by V'ger that it even contained the real Ilia's memories, which were deeply suppressed. Decker, however, was able to access those memories and establish a personal rapport with the probe. Later, when he learned that V'ger needed a "human element" to reveal its data – and, in so doing, stop its attack on Earth – he input the final code sequence manually, and, together with the Ilia probe, merged with V'ger.

Legendary Klingon warrior andDaharMaster whose exploits assured him a place in the Hall of Heroes, as told in G'Trok's poem "The Fall of Kang", an epic so important it is required reading at Starfleet Academy. Commander Kang once faced James Kirk in 2269, but later joined him to defeat their true enemy, an energy life form living off their shared hatred when trapped aboard theEnterpriseas undying fodder. Captain Kang later squared off against Captain Sulu's USSExcelsiorduring the tensions preceding the Khitomer Conference in 2293. Kang had already met Curzon Dax by then on the Klingon colony Korvat, when Dax intentionally angered Kang to foster a bond—a calculated risk as he walked out during a long diatribe by the shocked Klingon. The Trill envoy became such a trusted family friend that Kang's firstborn, a boy, was made his godson and named "Dax" in his honor. The boy was among those later killed in revenge by the marauding Albino and fostered a blood oath of revenge in turn among Kor, Koloth, and Dax that was finally carried out in 2370 and led toDaharMaster Kang's death as he struck the death blow on his enemy. He also had defeated T'nag and his army with only colleagues Kor and Koloth, according to Kor's tale in 2372, and later feasted on the leader's heart.
Rayna Kapec	Louise Sorel	Requiem for Methuselah(TOS)

Kargan	Christopher Collins	A Matter of Honor(TNG)
Klingoncaptain of theIKS Paghin 2365. He was short, heavyset, and demanded strict adherence to his authority. When he learned of the space organism eating away at a small section of thePagh's hull, and that theEnterprise-D had directed an intense scanning beam at that specific area for two minutes, Kargan believed the Federation starship had landed a first strike against his vessel, so he vowed to attack and destroy theEnterprise-D. He suspected that CommanderWilliam Riker,his acting first officer, was complicit in theEnterprise-D's attack, so, to test his loyalty, Kargan demanded to know the surest method of attack against the Federation starship. When Riker refused to break his oath toStarfleet,Kargan relented, knowing at least that Riker wasn't a traitor or a coward. When Riker activated an emergency transponder given to him byWorf,Kargan, believing it was a weapon, demanded that Riker give it to him. Kargan was then beamed aboard theEnterprise-D, and Riker was able to assume command of thePaghand defuse the brewing battle. Later, when Kargan was returned to thePagh,Riker refused to resume his station, so Kargan slugged him and ordered him removed from the ship. That action allowed Kargan to save face and regain honor in the eyes of his officers, and likely averted an assassination attempt by LieutenantKlag.

In the altered timeline, Keeler, a passionate believer in peace, founded a movement which delayed the entry of the United States into World War II, thus paving the way for an Axis victory. Subsequently, Starfleet, the Federation, and the USSEnterprisewere gone, but the proximity to the Guardian of Forever by the landing party allowed Captain James T.
