Lotta Blackwood has dark brown locks, and one blue eye and one brown. She has sharp face features and a light skin. She's 152cm tall and has normal weight. She often wears her hair in high ponytails, braided or down. When she's not wearing the uniform, she likes to wear skirts and tights with blouses and Sleeveless sweaters, mostly in black or a forest green or simple tops. Her parents always tell her that she fits into all colors but they want her to wear elegant clothes, she likes both. Also she wears sometimes gold and sometimes silver jewelry.

Lotta Blackwood loves magizoology and magical creatures overall. Her favorite color has always been a deep forest green and her favorite creature, the Kelpie. Lotta often writes journal to let things out because she's not the best at expressing emotions, she either cries very quickly or gets aggressive. Her favorite subjects are care for magical creatures and potions. She admires quidditch and her dream is it to become a seeker one day.

Lotta comes from a rich family that provides everything, still she didn't come out as spoiled brat but as a loving little girl that always has to help every creature in need. She doesn't have too many friends but a few right ones. She's loyal to the core and would protect her friends without a doubt. She loves both her parents and her home but they aren't really happy about her dreams and her liking to magizoology, they'd rather have her do something "real". (Their words)

When Lotta was mad as a little child at the age of three, she accidentally made a faucet "explode", splashing water into her father's face after he angered her.
