Mar-Vell and Phyla-Vell were law enforcement officers who crash landed on Earth while pursuing a criminal. Their ship crashed in what would be Guatemala. With their spaceship damaged beyond repair, the couple adopted Earth as their new home. Using their advanced technologies, the couple made the barren land thrive. In gratitude, the people worshiped them as gods and declared them King and Queen. As the rulers of that region, the couple set about bringing the benefits of Kree rule to mankind; building a strong empire and military presence that provided stability to the region.
