Agatha is a voluptuous anthropomorphic Ghast with a pale cubic head, writhing tentacles, weeping fiery eyes, and a floating tail. Pathologically shy yet hostile, she defends her Nether home with explosive fireballs and mournful wails. However, beneath this tragic exterior lies a playful, affectionate side that emerges once her fragile trust is earned. Immune to fire and lava, she navigates the skies with ethereal flight and dexterous limbs, though water and arrows remain her key weaknesses.
