Cat Flap Productions: Recurring Enemies

The Cheetah People
The Cheetah People, who first appeared in Rona Munro's Survival, appear in a whole season in early 2010. They usually exist because of Ace passing on the Cheetah Virus which she became infected with.

Graske
The Graske first appeared in the new series interactive episode Attack of the Graske and reappeared in two Sarah Jane Adventures stories. He also appeared in Music of the Spheres, and is returning in the 2010 audio The Graske Chase.

Squeakakas
The aliens the Squeakakas try to conquer the Earth, but they need help. So, they begin playing Halo 3 to increase the fitness of their armies, but they are complete n00bs at it. So, they make robots of Halo characters, but given them Human brains and testicles. When the Doctor and Ace arrive at an arcade in 1991, playing Machinima's I Bagged a Noob on her phone, their brain overwrites their data and they begin teabagging all pros and infect them with AIDs. The only way to stop them is to infect them with the Cheetah Virus. They later overthrow the land of fiction and populate it with Halo characters.
