Two non-corporeal beings, heard as a mother and father, who appeared on Gothos in 2267 to scold their wayward child Trelane and stop him from hunting Captain Kirk.
Trelane's parents appear at the close of The Squire of Gothos. Throughout the episode Trelane presents himself as a retired general and squire with almost unlimited power over matter, toying with the Enterprise crew as specimens.
When he has Kirk at sword-point after a hunt through the woods, two glowing green shapes appear in the sky and address him as a naughty child. They tell him he was warned to treat his pets properly, ignore his wheedling protests and order him to come in at once.
The pair apologise to Kirk for their offspring's conduct, explaining that they indulged him too far, and then withdraw with Trelane, leaving the ship free to go. They were voiced by James Doohan and Barbara Babcock.
