Macavity is the feared outlaw of the Jellicles. He was shunned for some reason and now he has no contact with the Jellicles. He had a relationship with Demeter and he must have been terrible to her because she fears him greatly. He also possibly had a relationship with Bombalruina but she doesn't seem as upset as Demeter, perhaps she's not so easily frightened. Macavity's arch nemesis would be Munkastrap for always foiling his evil plans. Macavity is one of the best criminals around, no one can seem to catch him. he's a conjuring cat like Mistoffelees helping him escape capture.

Macavity is red black and white. He's one of the less seen cats, and probably around the age of 24 human years.
