Legend of the Sea Devils (TV story)

Legend of the Sea Devils was the 2022 Doctor Who Easter Special. This episode introduced the Sea Devils into the BBC Wales revival series, last seen on television in 1984's Warriors of the Deep.

Unlike the 2010 redesign of the Sea Devils' sister species, the Silurians, in TV: The Hungry Earth, these returning enemies remained largely faithful to their original designs, with CGI augmentations mostly allowing for a greater variety of expressions.
