Aracely is supposedly the host to Huitzilopochtli, the Aztec God of War. She is the sole survivor of a human trafficking operation. She was saved from a container filled with dead bodies of immigrants by the new Scarlet Spider.
The Salamander later began hunting her down in an attempt to kill her and was opposed by her "guardian" the Scarlet Spider.
When Kaine is hired by the assassins guild to kill Wolverine, Aracely comes along with him. Donning a costume and calling herself "Hummingbird" she uses her abilities to infiltrate the Jean Grey School and even take out quite a few of the mutants herself.
