Maria Ross

Second Lieutenant Maria Ross is one of the soldiers assigned to watch over Edward and Alphonse Elric. Maria Ross is the partner of Denny Brosh. Both are introduced when they are assigned to protect Edward Elric, who she develops a maternal affection for. Envy takes her form in order to get close to Lieutenant Colonel Maes Hughes, and kill him.

In the anime, Ross later appears in the rebellion against King Bradley, saving various characters from execution. In the manga she is framed by the homunculi for the death of Maes Hughes. Roy Mustang stages a prison break and then fakes her death, giving her a chance to flee to Xing. Before leaving she asks that her family and Brosh not be told that she is alive so as to keep the secret from getting out. Ross later returns to Amestris to repay Mustang for saving her life, so she helps wage an assault on Central.
