He duelled with the newly-regenerated Tenth Doctor and cut off his hand which, owing to the after-effects of regeneration, grew back. This allowed the Doctor to defeat him. When the Doctor's back was turned, the leader tried to kill him again, but the Doctor used a satsuma from his borrowed dressing gown to hit a button which sent the leader falling to his death. The Doctor justified his action by stating, "No second chances. I'm that sort of man." (TV: The Christmas Invasion)
The Great Intelligence mentioned, among others, the death of "the leader of the Sycorax" at the hands of the Doctor to dispute Madame Vastra's claim that the Doctor was never "blood-soaked". (TV: The Name of the Doctor)
