Dark Moon Clan were originally from the future? Well we shall simply have the same concept. A time loop caused the family from nemesis to be transferred to earth in 2011. (Prince Diamond, Saphir, and Rubeus) all brothers with a cousin from their adopted father's second wife, (Esmeraude). Now, they have grown up on earth and quite successfully.
This male has grown from being an orphan in one of the dirtiest orphanages to one of the strongest men in New York. (You can choose his successful profession) He is creative in schemes and planning, which are two of his strengths.
Second male of the family he isn't quite as successful as his older brother. He is incredibly loyal to his brother, though he isn't always sure what his brother has up his sleeves. He is slightly more laid back than his brother.
The youngest and he's very impulsive and wanting to prove himself though he isn't sure how. He is loyal is unwavering to his brothers, even if he is a bit of a womanizer.
Older than (Rubeus) but younger than (Saphir), she is wanting to hang with the guys. She has had a crush on (Diamond) and might still have one now that caused her to dress and act a lot more feminine in order to show that she could be the woman of his dreams.
