Fairy Tail (2009)

Season 2: Episode 16

Erza manages to overcome Midnight's illusory magic, while Natsu, Gray, Lucy and Happy confront Brain's staff, Klodoa. Realizing Midnight's defeat, Klodoa explains that Brain has an alternate destructive personality called Zero that was kept sealed by the members of the Oración Seis using body link magic. The seal is released and Zero emerges and defeats Natsu, Grey, Lucy and Happy with ease. Erza, Jellal, Wendy and Charle make haste as Zero initiates Nirvana to fire upon Cait Shelter.
