Thasus

Thasus is a fictional planet featured in the Star Trek multimedia franchise. It is referenced in the second episode of season one of the original Star Trek series, "Charlie X".

Description
Thasus is the fourth planet located in the Thasus star system. According to official Starfleet sensor logs, it is incapable of sustaining human life. Thasus is the homeworld of a powerful race of beings known as the Thasians. Little is known about these creatures save that they can assume human form if need be, they can project their consciousness across vast distances and they possess strong psionic abilities such as mind control and telekinesis.

In 2252, a civilian transport shuttle carrying the Evans' family crash landed on Thasus. The only passenger to survive was three-year-old Charlie Evans. The Thasians monitored Charlie and when food supplies ran low, they imbued him with a portion of their power, enabling him to survive Thasos' rough terrain.

Fourteen years later on Stardate 1533.6, a Federation cargo freighter, the USS Antares discovered Charlie Evans on Thasus and took him off world. They found that his closest living relatives were on Colony Alpha V. They contacted the USS Enterprise, which was en route to that sector and Captain James T. Kirk agreed to pick Charlie up and bring him to Colony Alpha V.

A hormonally imbalanced and socially inept young boy, Charlie used his powers to take control of the Enterprise, threatening the lives of everyone on board. When the Thasians discovered this, they made contact with Captain Kirk and explained to him how Charlie got his power. They teleported him off of the ship and brought him back to Thasus.
