In the Sailor Moon S movie, Luna was briefly transformed into a human to be with a human she fell in love with a human named Kakeru.

Artemis- Artemis is the second guardian cat on the show. He is white with a crescent moon on his forehead. He is the guardian of Sailor Venus. Artemis is usually picked on by Luna and the others, being the only male in the group. He was also the voice of central control that Luna was going to for advice, until Luna discovered his plot.

Diana-Diana is the last kitty guardian to appear on the show. She is the daughter of Artemis and Luna, though Artemis didn't know that at first, and Luna was furious about it. She appeared in the Supers series and went back to the future with Chibiusa in the Sailor Stars series. Diana is a light grey, with a tint of pink. Diana is the kitty guardian of Chibiusa after the Luna-P ball.
