Nathan Goss was a child prodigy who worked at the Pharos Institute. He was killed by Korst Gogg Thek Lutiven-Day Slitheen, who took his skin as a disguise. He created 'MITRE'.

When Korst Gogg Thek Lutiven-Day Slitheen was disguised as him, he came across as being (in the words of Sarah-Jane Smith) 'an obnoxious brat'.
