Alien invasion is what happens when aliens come to your world to jack your stuff! It sucks.
In television Edit
In the year 2013, seven alien races collectively known as the Votans came to Earth and began terraforming it. In addition to wreaking geological upheaval, the terraforming also caused hundreds of species of animal to go instinct, while causing a forced evolution in others. In some cases, entirely new breeds of animal were coming into being. This incursion resulted in a human resistance which led to a series of revolts known as the Pale Wars. In 2031, an armistice was declared and the Pale Wars ended.
