Zygon McGillop
From Tardis Wiki, the free Doctor Who reference
A Zygon was part of the group stuck on Earth. Their ship landed in 1562, but the group retreated into a stasis cube and stayed there until the 21st century, where this Zygon took McGillop's form.
Later, three of the [[The Doctor|Doctors[[ erased the memories of both the humans and their Zygon counterparts, and peace was restored. (TV: The Day of the Doctor)
