Ice Warrior (The Rings of Akhaten)

Despite the great dishonour of being seen without its survival armour, (TV: Cold War) an Ice Warrior without any armour was present in the market (TV: The Rings of Akhaten) on Tiaanamat, (PROSE: Susan's Diary) which the Eleventh Doctor and Clara Oswald walked past, seemingly not noticing it. (TV: The Rings of Akhaten)

The Ice Warrior displayed the typical physcial attributes other Ice Warriors were recognisable for, including the large physical build and flattened faces complete with black eyes. (PROSE: Legacy, PROSE: The Medusa Effect, TV: Cold War, COMIC: Descendance) However, when the Doctor later met Skaldak, this Ice Warrior had a ridged face with red eyes, and the Doctor claimed that "[he'd] never seen one out of its armour before." (TV: Cold War) Another Ice Warrior was later present on Trap Street in London without its armour, under the protection of Mayor Me. (TV: Face the Raven)

Behind the scenes
This design of an Ice Warrior was intended to be used for Skaldak in TV: Cold War, but due to the physical prop being much smaller than they had wanted, the Skaldak was obscured in most shots, and when Skaldak's face was seen at the end, it was replaced entirely with CG, also changing various details from the prop as well as previous appearances of Ice Warriors in other media, such as changing the eye colour from black (as seen in COMIC: Descendance) to red. However, this design was used in the Cold War Time Zone Playset 1983 from Character Options, although the eyes on this figure were painted red to more closely resembled the design seen in Cold War. The prop was evidently reused in The Rings of Akhaten.
