Shockeye's fellow Androgum, Chessene of the Franzine Grig, had had her intelligence artificially increased by Dastari, the commander of Camera. The trio called in a legion of Sontarans including Group Marshal Stike and Major Varl to kill all aboard but them. They travelled to 20th century Spain and devised a plan to use the research from Camera to uncover the secret of time travel.
When the Second Doctor was temporarily transformed into an Androgum, Shockeye killed a lorry driver to acquire his vehicle and brought the Doctor to Las Cadenas, a restaurant managed by Oscar Botcherby and his girlfriend Anita in Seville. After eating an enormous meal and running up a bill of 81,600 pesetas, Shockeye promised to pay with a twenty-narg note, but Oscar refused. Enraged, Shockeye stabbed him to death with a meat knife.
Back at the house, Chessene and Dastari captured both the Second and the Sixth Doctor and chained them up with their companions. Chessene allowed Shockeye to take Jamie to be eaten. When the sixth incarnation escaped, Shockeye was commanded to postpone the killing and chase him down. The Doctor used some cyanide left by Oscar when he was hunting moths to smother Shockeye and kill him. (TV: The Two Doctors)
