10 Star Trek Characters You Didn't Realise Died Horrible Deaths
4. George Samuel Kirk
Newer fans may not know that Kirk's brother George Samuel Kirk had actually appeared (and been brought up in conversation) in The Original Series before showing up as a recurring character in Strange New Worlds. Unfortunately, Sam Kirk is destined to meet a horrible fate in his future.
In the Original Series episode Operation - Annihilate!, the Enterprise was called to investigate an outbreak of mass insanity travelling through the galaxy in a straight line. The next planet in its path was the Deneva colony. Sam Kirk and his wife Aurelan had been on the previously infected planet Ingraham B and had recently arrived on Deneva, carrying the parasites responsible for the outbreak. The parasites caused them to lose control of their minds, lashing out erratically and working in tandem with the other infected to spread the parasites as much as possible.
In the end, the Enterprise was able to defeat the parasites using ultraviolet light generators, but both Sam and his wife Aurelan were killed.
