Triskaidekaphobe
From Tardis Wiki, the free Doctor Who reference
The Triskaidekaphobes were a group of thirteen individudals who feared the number 13 yet included 13 in their number (including Brothers Anguish and Melancholy, Sisters Misery and Misfortune) and who were led by Father Tragedy. They were clones, the unluckiest people in the galaxy, whom Bob Kreesus fed on all their luck and good fortune. They dressed in black Cowls of Gloom and lived in the Castle of Despair on the 13th moon of the 13th planet in the 13th galaxy, trapped until the the Doctor and Rose Tyler arrived and changed their luck.
