Lullaby has two forms and thus, two appearances. It has its initial and default Flute Form and its Etherious Form.
While in its flute form it is unable to speak, move or take action; and its size is nearly 50 centimeters in length. It has a skull with three eyes on one end, and an oval-like cutout in the skull's brow. On the other end, there are root-like cutouts.
When the flute transforms into its Etherious form, it becomes an extremely tall beast that has three eyes, two legs, two arms and one head. There are many cutouts in its body.
The flute was once just a tool for "murder by curse" at first, which means that it curses the target and causes them to die. After getting into Dark Mage Zeref's hands, he further developed it into a magical flute, called Mass Murder Curse Magic that is capable of putting a death curse on everyone who hears its melody except for the Caster.
Erigor hoped to use this to kill the Guild Masters at their meeting. As Kageyama failed to carry out the mission due to regret for his actions, Lullaby transformed into its Etherious form to feast on souls. However, Natsu Dragneel, Gray Fullbuster and Erza Scarlet were able to easily defeat the Demon flute. Once reverted to flute form, the light in its eyes and mouth faded away and his face cracked, eternally broken. It currently is in the Council's hands.
Magic and Abilities
Etherious Form (エーテリアス フォーム Ēteriasu Fōmu): Lullaby has the ability to transform into a large beast with three red eyes, two arms, two legs, and one head. Various cutouts are also seen from its body.
- Magic Beam: While in its Etherious form, Lullaby is able to fire a magical beam from its mouth through a Magic Seal that is powerful enough to destroy an entire mountain in a single shot and the magnitude of such attack is enough to scare a battalion of the Fiore Royal Army into a full retreat.
