Chantho
From Tardis Wiki, the free Doctor Who reference
Chantho was a female Malmooth, and the last of her kind. She left her dead city and worked with Professor Yana of the Utopia Project. When Yana discovered that he was in fact the Master in Human form, he fatally wounded Chantho with a live electric cable.
Her final action was to shoot the Master, triggering his regeneration.
