I've mentioned before that Toei tends to revisit the themes and character types it really likes, and it's pretty obvious that for Toei, and especially Kamen Rider, creepy children rank up there. They rank so high that though this list was originally meant to include both Kamen Rider and Super Sentai, by the time I'd finished counting all the creepy children populating Kamen Rider I'd completely run out of space for, well, Kibaranger.
"Children", in this sense, means any character under the age of eighteen, albeit with a focus on characters towards the lower age range. With that aside, let's view the nanny's nightmare gallery!
