The planet from which Pxldt originates is a mountainous and arid place with no moon. The distance from the planet to its sun is closer than that of Earth to Sol. The gravity is slightly greater than Earth's gravity.
There was a dictator taking advantage of his people. Pxldt was among those who rebelled against this injustice. Word came to the rebels that an alien technology had been discovered. Both the dictator and the rebels sent teams to find this technology. The rebels wanted to find it before the dictator did, just to keep him from using it for selfish purposes.
The teams met and clashed, and a long, tiresome battle ensued. The rebels were losing, and Pxldt attempted to turn the tide of battle by going closer to the alien technology. The battle seemed to awaken the device, and suddenly, Pxldt was sent into darkness.... and landed on a world full of strange things.
Personality
Pxldt has an extreme dislike for injustice, as one already can tell. Here on Earth, she will defend others against whatever she feels is injustice -- regardless of the human moral view of the situation.
Humans have many things that Pxldt did not, and vice versa. There are some ways she feels humans are inferior and other ways superior.
Powers/Abilities
Pxldt's abilities come from features all her people have. She has wings that do not propel but glide, retractable claws used for climbing the mountainous slopes of her home planet, and strong limb and back muscles used for scaling said slopes.
Also, her people have hollow bones in order to make them light enough to float on their wings.
