Perpetual Pete

Perpetual Pete was non-human, around seven hundred years old. He worked as the 'Health & Safety' man for the 'Death Ride', making sure some tunnels were Off-Limits. However, he was actually protecting a chamber called the Perpetuity Chamber, which kept horrible beasts inside.

After many questions from the Doctor, he was forced to explain that he was the guardian of this chamber after they captured the Drexxon who had become quite vicious and violent and were destroying planets. When hearing about a Drexxon in the faiground he became quite shocked and decided that they would have to take action. A musical lock opened the chamber and Garvo was the key. (NSA:  Death Riders)
