The monsters made their debut in the 1967 story The Ice Warriors where they faced Partick Toroughton's Doctor. They returned to the show in The Seeds of Death which was broadcast in 1969. They made two further appearances alongside Jon Pertwee. The first was in the 1972's The Curse of Peladon and the second in the 1974 story The Monster of Peladon.
The Ice Warriors are reptilian humanoids who originate from Mars.
The Daleks will also be making an appearance in episode one of the new series which is written by Steven Moffat. A shot of a Dalek's eyestalk was shown in the trailer which will be available on the BBC website from 9.00am tomorrow.
The TARDIS set has also been given a slight makeover, including a new wall.
