Saphir

Saphir is a character from Pretty Guardian Sailor Moon and is a minor character in the Knights of the Multiverse Mini-Series. He's a member of the Black Moon Clan (and subsequently the Heralds of Unicron) and is the younger brother of Prince Dimande.

Personality
Unlike the other members of the Black Moon Clan, he doesn't fight against the Sailor Senshi and only follows out his elder brother's orders like a butler of some sort.

Megatron
Saphir never trusted Megatron from the moment he arrived on Nemesis, believing that he had some ulterior motive.
