Doomsday Trash, Power Sovereign

After the apocalypse, only Freya has no power-the "useless" one. Secretly, she is the walking Wi-Fi hotspot fueling her family's powers. When true heiress Sophia returns and turns everyone against her, Freya is thrown into a zombie pit. There, her four powers awaken. She takes back everything, finds love with Aiden, and becomes humanity's savior.
