Brianna

Brianna is an engineering student and prospective astronaut. She is a very intelligent student, and was Astro's first romantic crush. She only appears in episode 36, "Space Academy", in the Astro Boy 2003 series.

Personality
Brianna is a highly skilled and intelligent student at the space academy. She can come off as an airhead, but that is only because she is almost always thinking hard about her studies. She aspires to one day be an astronaut and engineer. In the original Japanese version, Brianna finds Astro adorable and treats him like a little brother, but still maintains a polite and formal tone with him. However, in the English dub, she is strangely changed to be more coy, with some of her lines altered to seem like she is flirting with Astro.

Appearance
Brianna is a human in her early 20s, with fluffy blonde hair and green eyes. She is tall and lithe, but still slightly athletic. She usually wears her academy's uniforms and flight suits, but on occasion, has worn feminine modest casual clothing.

Story
Brianna first met Astro when she saved him from Anton's loose fireball, which she disabled on a second's notice by identifying one of its power cords. Astro visited the academy to help design the Horace 2 rocket's guidance system, and Brianna was very impressed with Astro when considering his age. Brianna is passionate about the Horace rocket project, and is eager to talk to Astro about it. She was accepted as one of the first astronauts to go on it to space. Brianna is primarily focused on her studies and research, particularly with rope theory and time theory. She is an introvert and does not have a lot of close friends outside of her studies. She has been ridiculed for her studies into transcending time, and feels a great bond with anyone who takes her seriously.

Both Anton and Astro have romantic feelings for her. Brianna obviously is not interested in Astro, but she is good friends with Anton, and initially accepts his advances. This begins to change after Anton gets Astro's help in writing Brianna a love letter and suggesting things for him to say during a meeting with Brianna. However, she is hurt and feels cheated when she finds out the truth. In the end, Brianna proceeds on with her mission to space, staying single but still remaining friends with Anton and Astro.
