Percy Jackson and the Olympians: Legends

Alex is a teenage einherji, and shares a lot of physical traits with her mother Loki. She is petite, with sharp and beautiful facial features and the same sly grin as the god of lies. She has heterochromia, with one dark brown and one pale amber eye, and her hair is dark at the roots but dyed green. She also has a tiny symbol of Loki tattooed on her nape. Magnus noted that Alex's physical appearance did not change when she was a boy, except for her hair, which actually seemed to be longer. Alex dresses rather flashily and flamboyantly, in primarily pink and green. She wears a pink-and-green argyle sweater-vest over a white tee, skinny lime green jeans, and battered rose high-tops. Tied around her waist like a kilt is a cashmere sweater, which conceals a garrote wire and a hunting knife tucked behind a belt. Her appearance has been compared to both a jester's motley and a venomous animal giving off warning signs.

Alex Fierro is, as a character and a person, one who refuses to be put in any box. People often assume things about her based on her gender identity and parentage, and are often scared to get close to her or trust her as a result. Her transgender identity shaped her personality in particular, specifically the way she was treated because of it. She was bullied, abused, and kicked out of homeless shelters. However, she is very proud of her trans identity and is very happy when people like Magnus and her Abuelo respect it. She is actually very open minded, not expecting people to understand or even demanding it, just wanting respect. Alex Fierro, under everything, is a very friendly person. Though people are often scared of her, she makes a point that she is not fragile and not contagious. She has a very sarcastic and snarky sense of humor with her friends, and though Magnus is insecure about it, Alex really does mean well and cares for her friends a great deal.

Alex Fierro is the Norse demigod child of Loki and Mr. Fierro. Alex is a genderfluid, formerly homeless teenager from Boston, Massachusetts. Due to Alex‘s gender identity and being the child of a Norse deity, she was constantly berated, harassed, and assaulted by others and eventually disowned by her own family. Alex is currently in a relationship with Magnus Chase.
