Starman

Starmen are a strange breed of peaceful energy-based individuals.

Physiology
The Starmen seem to be a species made up of energy, as their "true form" is simply a ball of light. They are a peaceful race who find interest in exploring other worlds and observing other life forms.

When a Starman arrives on a world, they can use a simple strand of DNA to create an "environmental suit" by cloning a human body with which they can physically interact with other species. When creating an enviromental suit, they alos create several 'silver spheres' that can be used for different tasks such as communicating telepathically, creating energy sheilds and healing/restoring life among other uses.

Starmen are also shown as been able to interact with technology, as the Starman on Earth was shown as been able to change a channel on a television simply by touching the screen and win cash on a gambling machine just by touching it.

Earth
Not much is known about the history of the Starmen. Whether they originated as energy beings or evolved into such through years of evolution is especially unclear. What is known, however, is that they have frequently explored Earth.

The launch of Voyager II unwittingly attracted on particular Starman to Earth. When his ship crashed, he travelled to a nearby house, and through a lock of hair cloned a body resembling that of a dead man named Scott Hayden. After sending a distress call, forced Scott's widow, Jenny to take him to Arizona where he could rendezvous with his ship.

Over the course of the journey, the Starman struggled to understand Earth's society - complicated by Jenny's intial attempts to escape from him. He slowly learned to speak English with some help from Jenny, and developed a particular fondness for Dutch Apple Pie - with Jenny deciding to help him after seeing him use one of his spheres to bring a dead deer back to life that a hunter had killed. Eventually the Starman began to experience what is known as love, shown as when he saved Jenny after she was fatally wounded and brought her back to life. As a gift for her, he gave Jenny a baby boy after making love to her (she was previously infertile and unable to give birth) - explaining the baby would be the son of her and her deceased husband but also his, with the baby having the starman's knowledge and growing up to become a teacher. Upon her request, he pointed out where his 'star' was so she could later tell her child where 'his father' came from.

With some help from a SETI scientist, Jenny and the Starman were finally able to make it to the rendezvous point in Arizona, where a large spaceship came to pick him up, presumably taking him back to his homeworld. Before leaving, he gave the last of his spheres to Jenny - stating her child would know what to do with it.
