Animus is an antagonist of the Fairy Tail movie Dragon Cry.
Animus first appears before Zash who he proceeds to bind with his power due to the latter's incompetence in allowing the staff to fall into enemy's hands. Zash pleads that he will use Sonya in order to retrieve it but the king tells him he is not put her in harm's way, granting him to take the Three Stars with him to retrieve the staff not knowing that Zash tries to betray him. He later visits Sonya's room unannounced to comfort her about retrieving the staff while after she and Zash completed the task he finds her in the courtyard and asks of the staff, which she says Zash has it, angering him saying they need it for the ceremony.
Animus binds Zash after putting Sonya in harm's way later on while ordering him to kill the enemies when they show up. Animus appears before Sonya at the ceremony the next day and asks for the staff which she refuses, with Animus later revealing in front of Natsu that he has been inside Sonya recovering while manipulating her mind.
After the two talk of Igneel and why he cannot release his body without Dragon Cry Sonya fights back Animus' control and tries to deliver the staff to Natsu. Zash steals it with Animus releasing his true body to chase down the traitor, who of which warps his mind causing Animus to rampage. After Zash is killed, Animus and Natsu struggle over the Dragon Cry. Animus wants to return the age of Dragons, piercing Natsu while swallowing the staff to return to full strength. Sonya tries to intervene but she's pushed to the side while Natsu attempts to fight back. Natsu exerts his E.N.D. power, violently attacking Animus who recognizes that he is E.N.D. and the one who will destroy everything, eventually defeated not long after this revelation. Sonya comes to a decaying Animus to thank him for raising her, with Animus' last words being he was finally able to see her smile.
