Some time before 1815 he became a soldier. As a soldier he stood with the Duke of Wellington at the Battle of Waterloo. It changed Blazington. He felt the need to hunt that was why he became an animal hunter.
Later Blazington was captured by the Nadurni. They used their gene manipulator on Blazington. Blazington turned into a big creature, part human, jaguar, caiman and tarantula. He had needle shap teeth, was over 8 feet tall and powerfully built. His head and body was covered with patchy fur. However he was still human enough to saved Rory and Amy from the Nadurni. He also helped them to find the Doctor.
The Doctor was also captured by the Nadurni. They wanted to turn the Doctor into a mutated monster that would fight for them, like the animals. Oliver Blazington saved the Doctor from the gene manipulator but got stuck in it. Blazington turned into an ultimate warrior, who's only mission was to hunt.
After this Blazington started to chase three Nadurni. He smashed everything in his way and advised the Doctor and his friends to flee before he would start to hunt them. Oliver Blazington died in an explosion together with the three Nadurni. (AUDIO: The Eye of the Jungle)
