List of Mixtus inhabitants.

Mixtus II settler and his wife 

This wealthy male and his wife were the sole inhabitants of Mixtus II. 

During a meeting aboard the  in 2380, he voiced his outrage over this demolition of a moon that was falling out of orbit, claiming that it blocked pollution from Mixtus III from reaching "[his] people", claimed that they would perish without the moon.

He quickly became hysterical, to the point of jumping up and down on a tabletop, screaming at Captain Carol Freeman and Commander Jack Ransom, calling them "murderers", and claiming that if they destroyed the moon, they would "have blood on [their] hands". He even attempted to convince Freeman that what they were doing was in violation of the Prime Directive. When Freeman eventually discovered that his "civilization" consisted of only he and his wife, as they were rich, she immediately ordered the moon to be imploded. Her order led him to cry out that she and the other officers were maniacs, and that he and his wife "just redid the floors". ()

Mixtus III inhabitants 

These seven individuals inhabited Mixtus III when the planet was threatened by its fifth moon with a disintegrating orbit. They watched the disintegrating moon, then fled from its general direction, as its orbit had reached a critical altitude. ()

Pro-moon representatives 
In 2380, these eight individuals, who represented interests of those in favor of preserving the disintegrating moon orbiting Mixtus III, met with Captain Freeman and Commander Ransom of the  aboard the USS Vancouver to voice their individual protests regarding the demolition of one fifth moon:

The first male argued that the moon in question was "one of the most important" of all the moons to which he and others like him prayed. 

The second male, a farmer, revealed that the moon controlled the tides for their summer crop.

A female who inhabited the moon argued that her family, which consisted of herself and two other aliens present, had lived there "for generations", and were unwilling to leave it.

The seventh individual, another male, argued that "moons can't plummet," and that such a thing was "something the government made up to control [them]".

Two additional representatives were also present, but their interests were not addressed.

To appease the bickering aliens, Freeman offered to collect three tons of moon dust to be relocated for those the first alien represented for worship. She then offered to install gravity systems to control the tides for the farmers. Then for the family, Freeman offered to relocate three of the members ancestral homes to the current sixth moon. Her resolution pleased the group and they happily departed the ship. ()
