Score card
From Tardis Wiki, the free Doctor Who reference
The Sixth Doctor kept a score card of all the monsters he had successfully and conclusively defeated, which included the Daleks, the Cybermen, the Ice Warriors, the Yeti, the Ogrons, Davros, the Silurians, the Snipes, the Sontarans, the Axons, Azal, Bok, Omega, the giant maggots, Roberta Tovey, the Wirrn, the Zygons and Sil. Thanks to said card, he eventually realised he had defeated every monster and evildoer in the universe for good, sending him into an existential crisis. (NOTVALID: The Final Script)
