Tisiphone

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