Dragon Cry, after soaking up the rage and anger of the deceased Dragons, appears as a blue and red crooked staff with a scaly design reminiscent of a Dragon. Its original form was a red ribbon that was in the possession of Sonya, which she used to tie her hair as a child.
100 years ago Dragon Cry, originally being the ribbon that tied Sonya's hair, was empowered by the emotions from the deceased Dragons Acnologia had murdered during the Dragon King Festival. All of the power sealed inside is said to be the equivalent to multiple Etherion blasts, thus having the power to destroy an entire nation if released, filtered as magic circles that rain down energy beams that reach as far as the whole continent of Ishgar. The number of magic circles are insurmountable, being that they were noticeably located all across the country of Fiore. The Dragon Cry's user can be vaporized if they lack the power to use it, as was the case with Zash Caine. The power can also replenish the health and body of a weakened Dragon, while also being noted that if a Dragon who used the Dragon Soul Technique on a regular human the power of Dragon Cry can release the Dragon from the container body, it can then be used to further empower the Dragon, causing their bodies' coloration to change.
