Cathrine Honeywater is twenty-two, but feels ancient. She is the Orange Alchemist. She enjoys other people's pain, and is down-to-earth. She worked as an assassin, but retired two years ago when she became the Orange Alchemist and started working for good.
The Yellow Alchemist, Daisy Clearwater, is nineteen. She acts thirteen, and is the only immature Rainbow Alchemist. She works in a small café, but always wanted to be a singer, so she can be caught singing in her private time.
Karina Ren Suzuki is the Green Alchemist. She is thirteen, and feels and acts thirteen as well. She goes to a public school, but skips most days to hang out with Strawberry and Terios.
"Dark" Angel Jones, the Blue Alchemist, is the only boy Rainbow Alchemist. He is eighteen and just joined the military but is already climbing the ranks. Dark feels forty-six, and is good friends with Riza Hawkeye and Jean Havoc. His dyed dark blue hair and natural red eyes make many people stop and stare. On his trans-muted outfit is a pair of fake angel wings that are sky-blue and actually work when he moves a piece of his soul into them.
Violet Thompson is the Purple Alchemist. She is the youngest Rainbow Alchemist, going on thirteen, but she acts eighteen. She is a better student than Karina, but helps out anyone who needs her help. She is a space-case, a day-dreamer, and a worry-wart. When something goes wrong, she punishes herself, often by hitting herself on the head. In school, she is often yelled at to stop day-dreaming and do a hard question on the board, but always gets it right. Her teachers think she ought to be put in a higher class. She has poor fighting skills, saying that she doesn't want to hurt anyone and always dodges the attacks.
The White Alchemist, Lyn Simmons, is twenty-five, but acts five years older than her age. She works in her uncle's library and book store, where she studies psychology books, because she wants to be a children's psychiatrist. She is independent and calm, but tends to lose her cool when under pressure.
"Black Cat" Catherine Bridges was appropriately made the Black Alchemist. She is just barely twenty-one, but acts and feels thirty-five. She works as a bartender and accepts no nonsense from her customers. She doesn't show intense emotions very often, will go along with just about anything, and is very practical and extremely blunt.
Terios is a were-cat Alchemist. He is fourteen in human years, fifty-two in cat years, but feels almost seven-hundred years old. He is of Xingese origins, and very shy. He often hides behind the Rainbow Alchemists. Terios was once a close friend of Mustang's before he was turned into a were-cat by a rabid cat-Chimera. Terios lives as a cat with Strawberry, and often accompanies her on her dates with Mustang.
