I put this one in english, because I hate FMA in french.
Edward Elric is an alchemical prodigy. He is the youngest State Alchemist to be selected by the Amestris State Military, having achieved the rank of Major at age twelve. His father's disappearance when Edward was young, the death of his mother, and a failed transmutation play a key role in his story. Edward's motivation stems from a love for his brother Alphonse Elric, for whom he is desperately seeking a way to restore to a human form after their alchemy accident. Due to this, he is also generally perceived to be very independent; he feels that he's the only one who can solve a problem. He is reluctant to accept help unless he feels it is absolutely necessary. Often, he feels a heavy guilt that the problem is his fault to begin with, and thus his responsibility to solve. This gives him a selfless inclination.
His automail limbs are made by his childhood friend Winry Rockbell. She's always kept busy with them, as Edward regularly breaks them during fights. She is constantly looking for new ways to improve them, whether it is an attempt at extending their lifespan or simply lightening the weight. In both the anime and manga, Winry is an extremely important person to Edward. In the anime series, no romantic feelings are ever explicitly stated, but in the manga, Winry is in love with him. Edward has also exhibited similar feelings, but constantly denies them.
Edward is extremely short for his age, but despite his small frame, he is compactly muscular. He is very sensitive about his height, and will humorously overreact to any comment about it. He makes a habit of breaking out into rants and frenzied outbursts. Despite all of the obstacles that Edward tackles in the story, he still displays a childish personality when it comes to things he despises, such as needles and milk. He is extremely idealistic--often to a fault--and strongly believes in Equivalent Exchange, using it as his personal philosophy. Despite his occasional bouts of immaturity, he is a selfless, strong, independent young adult that gains a reputation as a "hero of the people". During his early teens, he catches serial killers, robbers, and helps different types of communities throughout the country. A running gag in the manga series is that Edward has very poor taste in art. Whenever he transmutes an item, he tends to make it over-the-top, including spikes, skulls, or other demon-like touches. Many characters become angered when he fixes their broken items to suit his own odd taste.
