Eagle Sky (イーグルスカイ, Īgurusukai), was a prominent member of the Fairy Tail Guild and a former Fire Mage. After coming into contact with a Dark Mage, Eagle abandoned the Fairy Tail Guild and pursued to learn dark magic. At that time, Eagle was just thirteen years old, but because he descended from a prominent line of mages, Eagle was able to learn several forms of Dark Magic, all which were from Zeref himself. Since then, Eagle has constantly attacked and killed several mages who have opposed him and his followers. He also attacks Fairy Tail Mages who are on jobs, but does not kill them for he prefers to send them as messages to the guild, often stating he will destroy them.

Personality
When he was in Fairy Tail, Eagle was a kind and honest soul. He enjoyed helping his friends within the guild and was willing to following in the footsteps of his parents and go to any job. However, after gaining a deep interest in Dark Magic, he became cold and played pranks on fellow guild members. While this gained Makarov's attention, he thught that Eagle was playing jokes. However, one day, Eagle fell into a trap set by a fellow member where water fell on him. Enraged, Eagle casted a painful spell on the member and severely injured him along with two others. Because of this, Makarov expelled him from the guild and warned to never come back because if he did, he would do something he would regret. Not caring, Eage left, shortly after he set other spells on other guild members and disappeared with a malicious laugh.

Upon his transition to a Dark Mage, Eagle became manipulative, cold, sadistic, ruthless, remorseless and psychotic, to the point of insanity. Eagle's sadistic nature was seen when he coldly tortured Lucy Heartfilia after capturing her while she was on a job with Team Natsu, to the point where she couldn't stand. Although she was saved by Natsu in the end, Eagle said that he would do whatever it takes to destroy Fairy Tail once and for all.
