Tucker Family
About
These characters are all members of the Tucker family. While Craig Tucker dates back to the early first season, the rest of the family was mostly introduced in season 3's "Tweek vs. Craig". They seem to be on welfare according to "Here Comes the Neighborhood" and share a habit of flipping the bird, but can be caring and loving when times call for it.
It has been speculated extensively by fans that due to to their initially similar voices, mannerisms, and reddish hair, Thomas Tucker and Skeeter might be related, which would make Skeeter and his daughter, Red, also members of the Tucker clan.
