Oscar Botcherby

Oscar Botcherby was a resident of 20th century Spain.

Biography
Oscar collected Moths, using Cyanide to kill them even though it could harm him, and had a good friend named Anita, whom he took moth hunting. He met the Sixth Doctor outside the house occupied by the Sontarans.

Later, while looking after a restaurant for a friend of his, Shockeye and the Second Doctor (who had been temporarily transformed into an Androgum) entered his restaurant. After eating a huge meal, they refused to pay, and when Oscar demanded payment, Shockeye stabbed and killed him with a meat knife. In his dying words he told Anita to look after his moth collection.

Later, the Doctor used the cyanide left by Oscar to kill Shockeye, effectively giving Oscar his revenge. (DW: The Two Doctors)
