Hybrids are a main theme on WB sci-fi series Roswell.
Alien-human hybrids of the Royal Four were successfully created using DNA from both species. The process was aided by creatures known as the Gandarium. Two sets of hybrids were produced, one being a duplicate set. Hybrids physically resemble humans except for their blood cells.
