Noah

Noah is a character from Fullmetal Alchemist movie Conqueror of Shamballa. She is a quiet young Roma girl who travels around and whom Ed saves from being sold to the Thule Society. On the surface, she is proud of her heritage and lifestyle, but is unable to bear being discriminated for it. She has the unexplained ability to read the minds of others, becoming fascinated with Ed's world after witnessing his memories of it while he is asleep. Believing she wouldn't be discriminated in Ed's world, Noah assists Dietlinde Eckhart and the Thule Society in opening The Gate of Truth to "Shamballa" based on information from Ed's memories. She cries out for Edward to take her with him as he is flying into the gate. Shortly after this, Noah relents once Edward points out the errors of her ways, and leaves Munich together with the Elric brothers.

Noah exists on Earth as the counterpart to Rosé.

Trivia

 * In the 2007 OVA "Kids", one of Ed's great-grandchildren look like Winry showing that Ed married this world's Winry or his world's Winry, making it impossible for Ed to have a romantic relationship with Noah. However, Seiji Mizushima, director of the 2003 anime, Conqueror of Shamballa, and the OVA, confirmed that the OVA was not canon to any universe.
 * Apart from being each other's counterparts by looks, Noah and Rosé have several other things in common:
 * Both were orphaned with no families.
 * Both have worn long cloaks at some point. Rosé had worn a long white cloak when she was dressed as Holy Mother. Noah wore a long red gypsy cloak when traveling to the festival in Munich, Germany.
 * Both have turned their backs on Edward to fulfill their own goals: Rosé turned her back on Ed and Al to go with Cornello to help revive her boyfriend and Noah has turned her back on Edward to go with Dietlinde Eckhart to open the Gate of Truth to go to Shamballa.
 * Both of them like dancing; Noah a belly dancer, and Rosé a ballroom dancer
