Alecto

Alecto is one of the three Fury Sisters. She is sister to Megaera and Tisiphone. After Megaera has been defeated a certain amount of times, Alecto and Tisiphone will begin appearing, randomly replacing her at the end of Tartarus. Alecto does not appear in the House of Hades after she has been defeated. Unlike Megaera, whenever Alecto is vanquished, she is not taken by the Styx, but instead scatters into a flurry of red bats. This reflects how she is not allowed in the House of Hades.
