Starman

The Starmen are an energy-based species. Its true name is unknown.

Biology
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.

They also seem to be immortal and do not need food to survive in their true form, as the Starman on Earth complained about hunting.

Powers and Abilities
When a Starman arrives on a world, they can perform a "symbiotic transformation": they scan a simple strand of DNA to create an "environmental suit", essentially transforming themselves into a cloned body, which can be used to interact with other species. The Starman on Earth scanned a human DNA to create the suit.

When creating an environmental suit, they also create several silver spheres that can be used for different tasks such as communicating with their kind, creating energy force shields 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 turning on a projector, change a channel on a television and win cash on a gambling machine just by touching them.

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, after his people brought Voyager II aboard their ship and analysed the contents inside their mothership. When he flew to Earth with an "observation ship", he was engaged by a pair of fighters and his ship shot down. Having survived the crash, he travelled to a nearby house, and through a lock of hair cloned and symbiotic-transformed into a body resembling that of a dead man named Scott Hayden. After sending an "emergency transmission", he forced Scott's terrified widow Jenny to take him to Arizona where he could rendezvous with his ship in where he referred to in the transmission as "Landing Area One" - which would have to be within 3 days or he would die.

Over the course of the journey, the Starman struggled to understand Earth's society - complicated by Jenny's initial 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. Although saying he would stop it if she didn't want the baby, Jenny accepted her gift from him and, upon her request, the Starman 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 - despite military helicopters trying to prevent them from reaching the centre of the crater, 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.
