Male and Female
The parents of Thatch remain nameless through the series. They were never seen but can be heard whenever Thatch calls them.
It can be implied that they are nice and care for Thatch but they also pressure him to be the best as shown in the movie, where his mother wanted to know if he was popular and in "Sweet Dreams", where Thatch tells his father that he will make him proud by winning the Grimly Award (through cheating), although his father didn't sound convincted he still wished his son good luck before hanging up.
- His father has a Romanian accent.
