Juan Sánchez-Villalobos Ramírez is a fictional character in the Highlander franchise, which covers multiple timelines. Born under the name Tak-Ne, he is generally depicted as an Egyptian swordsman who is immortal, unable to die unless beheaded, due to an energy called the Quickening. Ramírez is notable for being the mentor and friend of Connor MacLeod, the main protagonist of the first three Highlander films. The film Highlander II: The Quickening gave the character an alternative origin as a sorcerer from the planet Zeist who becomes immortal when exiled to Earth, while the director's cut of the same film said he was still an immortal native to Earth but one born during a lost age of advanced technology that existed before recorded history.

The Kurgan is a fictional character from the first Highlander film. He is portrayed by Clancy Brown. He is an Immortal, the main antagonist to Connor MacLeod in Highlander, and the latter's ultimate opponent in the Gathering.
