Sebastiene

Sebastiene was an expert sportsman who hunted sentient life. He collected rare creatures, including Mmtefl Beasts, Zargregs, Moogs, Daleks, a Raston Warrior Robot and even an Eternal. On one occasion he set his sights on the Tenth Doctor, the last Time Lord. Sebastiene lived on Planet 1 in a very snowy area, where he occupied an eighteenth century, Earth style castle. He was fond of things from the eighteenth century and dressed in eighteenth century clothes. It was said that he made all his servants grow moustaches in the style of the era.

However, when he attempted to hunt and kill the Tenth Doctor, using the Society of Endangered Species to help, most of them turned on each other and Sebastiene killed the rest himself. He was last seen after his own Planet (Planet 1) decided it didn't need him anymore and he promptly with the help of the Doctor, Donna and Baris, destroyed a large part of its northern continent using explosive decoy robots. He tried to hold the Doctor hostage on the condition that he take him from Planet 1, but the Doctor refused. Sebastiene was then attacked by the last remaining hunter, the Carpalian Witch, and was last seen fighting it off with his sword alongside Baris.(PROSE: The Doctor Trap)
