In the episode "The Impossible Planet", they were controlled by the Beast. After the beast was defeated they were absorbed by a black hole.
They returned in the episodes "Planet of the Odd", where they redeemed themselfes completely by telling the protagonists that they are actually only controlled by the Humans who torture them to use them as slaves. After they had established their own city 100 years later, one of them reappeared in the end of "Waters of Mars" to tell the Doctor to visits them again in "The End of Time", where they predicted the return of the Master.
