Kor
Commander Kor was one of the "smooth-foreheaded" Klingons from the original series of Star Trek before they had the money to give aliens descent makeup jobs for their regularly occurring aliens as opposed to the ones who appeared only once.
Kor led a batallion of Klingons to occupy the neutral, but strategically located planet Organia in the TOS episode "Errand of Mercy" and appointed himself military govenor over the planet. Unknown to Kor, Kirk and Spock were among the population subjugated and they proceeded to launch a guerilla raid on the Klingon holdings on the planet. The Organians refused to let harm to come to either side. They refuse to fight the Klingons but they also prevent the Klingons from harming Kirk and Spock. Kor attempted to persuade them by killing hundreds of their citizens but they remained unconcerned.
It turns out that the Organians have "evolved" into energy beings and they put an end to the hostilities between the two space powers. Kor laments not being able to see the "glorious" war between the Klingons and the Federation. And thus we see the early stages of two sci-fi idiotic brain bugs.
