- You may be looking for the bus driver seen in the K9 television series.
The bus driver was the driver of Bus 200 when it travelled through a wormhole. Upon getting out of the bus he saw that the bus was not badly damaged. Whilst there, however, the driver heard that they had come through the wormhole that was connected to Earth so he headed into it. The Doctor attempted to stop him, saying, "The bus came through, but we can't." However, it was too late; the driver had already tried to run through. As he did, his body caught fire and when he reached Earth, all that was left of him was a burning skeleton. (TV: Planet of the Dead)
