Agent Brains (a.k.a. Braianna Robeaux) is a main character of Lucky Fred. Brains is the perhaps the most intelligent character of the series, though smart, in order to protect her secret identity, she does not do her best at school and acts average. Despite being only fifteen-years-old, she attends High School with her closest friends, Fred and Friday.
Her hair color is Big Stone-Cinder and her eyes (like her father's) are Magenta (dye). When in school and at home Fred has her hair tied and wearing a Blue (Munsell) shirt, Vivid cerise sneakers and Hacienda pants. While on missions, she uses her Amaranth suit with a logo of a P (because she works for "The Protectors"), Black sneakers and has hair loose and not wearing glasses.
Agent Brains is amazing. She's academically brilliant, humble, cultivated and totally in control. She is agile and strong like an Olympic gymnast with a black belt in every single martial art throughout the Galaxy, having been taught at the Protectors' Academy, where she was trained, and taught everything except how to be a normal girl. Now that she has been assigned to be on the Earth, she has to make an effort in order to pass for 'Braianna Robeaux', a nerdy awkward almost invisible girl, with bad attendance and bad grades. All the teachers think that Braianna doesn't try hard enough. When Brains is on duty, she radiates self-confidence and proves to be a real expert in engineering and robotic science. However, while at school, she feels insecure and incapable of understanding the nuances of the enigmatic human relations. Deep inside, Brains would like to be like every other girl.
