the new season of doctor who is starting this week.  in the previews, they have a line where amy asks the doctor “who killed all the daleks?”, and the doctor responded, “who do you think?” 

so, in honor of that, i want to note all of the genocides that have been featured during the reboot of the show:

9th doctor:
rose disintegrated the daleks in the first season finale (bad wolf, parting of the ways)

10th doctor:
torchwood 3 blew up an alien spaceship in “the christmas invasion” in season 2
in season 3, the cult of skaro created a new species—dalek-humans—and they were all killed before the end of the episode (daleks in manhattan, evolution of the daleks)
the doctor-donna clone killed all of the daleks with a reality bomb in the 4th series finale (the stolen earth, journey’s end)
in “the end of time” special, a main focus was on the doctor’s sealing his species within a time lock.

11th doctor:
the doctor wiped the weeping angels out of existence in the “flesh and stone” and “the time of angels”
i believe he also wiped out the vampire arachnids in “the vampires of venice”
