This unidentified Slayer was active around the fourteenth century. In the texts of the Aztecs she was referred to as a warrior princess.
She traveled to the Soul Glutton's native hell dimension, with the intent of killing the Soul Glutton and its family using an echanted sword that drained the target's energy. However, the Soul Glutton survived and when it founds its family dead, it swore revenge on the Slayer. However, as time passed much slower in the hell dimension than it did on Earth, the Aztec Slayer was long dead.
