Oscar's passion was stage acting, though he was working between roles as manager at Las Cadenas, a restaurant in Seville, owned by a friend of his. Oscar collected moths, expertly using cyanide to kill them. He had a Spanish girlfriend named Anita, whom he took moth hunting. In 1985, he met the Sixth Doctor outside the hacienda occupied by the Sontarans. Later, the Doctor used the cyanide left by Oscar to kill Shockeye, effectively giving Oscar his revenge.
