Dodo Chaplet

Dorotea "Dodo" Chaplet (born in 1949) was an Huguenot teenage girl and descendant of Anne Chaplet and paradoxically Steven Taylor.

She is a companion and adoptive granddaughter of the First Doctor but only for a short while.

She changes her voice a lot and often wears wacky clothing, such as men's tabards in the far future, but then again 24th century Steven was wearing 1960s clothes in the same adventure, so.
