Macavity

Macavity is a character in Andrew Lloyd Webber's Cats. He is the 'villian' of the show. He captures Old Deuteronomy (who is later brought back by Mr. Mistoffelees.) He fights with Munkustrap and other male cats as he tries to steal Demeter from them (leading to speculation that he may have a romantic attachment to Demeter, or in some opinions is using her to get back at enemies of his within the Jellicle Tribe).

Appearance
Macavity is usually portrayed as a ginger colored tabby. He is usually dirty or unkempt, with wild, knotted hair.

Personality
Macavity, like Mistoffelees, has some magical powers as he can appear and disappear almost instantly. When he sets off the electric spark to get away, many fans speculate that he is killed by it. This has not been confirmed.

Relationships
Demeter: Some fans believe they may have been mates, other fans believe that Macavity may have kidnapped her and did unmentionable things to her.

Bombalurina: Some fans believe that Bombalurina may be Macavity's daughter with Demeter.

Old Deuteronomy: Many fans believe that he may be the son of Old Deuteronomy.

Munkustrap: Many fans believe that Munkustrap is the brother of Macavity, and if he is the child of Old Deuteronomy, it deepens their rinvalry.

Rum Tum Tugger: Many fans believe they may be brothers.

Mr. Mistoffelees: Many fans believe he may be the son of Macavity with Demeter, due them both having a magical ability (if Macavity is confirmed to have magical abilities). Other fans believe that they may be brothers.

However due to the mysterious nature of the show, and this particular character, nothing has been confirmed.
