Amelia Black is a playable hero in Age of Empires III. She is the great-great-granddaughter of Morgan Black and the mother of Chayton Black. She was also the only girl to be a native of the Black Family. She is voiced by Tasia Valenza.
Amelia Black is the daughter of Nathaniel Black, who inherits the Falcon Company after her father's death. Even though the company was almost bankrupt by the time Amelia ran it, she continued setting rails for the US Army under the supervision of Major Cooper.
After the Mexican Army attacks the fort where the US Army is staying, Amelia meets Pierre Beaumont, a French prospector who is supposedly looking for helpers in his mine whom he'll share the gold with. In truth, Beaumont was the new leader of the Circle of Ossus, long-time enemies of the Black Family. Amelia almost falls for his trap, but is saved by her granduncle Kanyenke. Amelia then chases the Circle with the plan of completely destroying them.
With the help of the US Army, Amelia is able to destroy several Circle bases. After Beaumont kills Cooper, Amelia finds herself in the middle of the war in Southern America, where she helps Simon Bolivar liberate several villages. In the final battle in Havana, Amelia, Kanyenke, and the US Navy destroy the Circle of Ossus's last stand, the Ossuary. Though Beaumont survives at first, he is shot by Amelia when he tries to kill her with a knife.
Amelia is the only other member of the Black Family to meet Morgan. At a railway station, an 'Old Coot' approaches Amelia wearing Morgans Armour.
