Klodoa

Klodoa is a magical staff used by Brain. Klodoa is the seventh member of the Oración Seis but just as a Brain's staff. Brain used Klodoa for casting his Darkness Magic, but Zero had no need for Kloda and crushed it to pieces. Klodoa can speak human language and levitate on air.

Oración Seis arc
Klodoa is revealed to be animate just before Midnight's defeat to Erza Scarlet. He appears in front of Gray Fullbuster, Natsu Dragneel, Lucy Heartfilia and Happy, deriding Brain's inability to take down more than one of the alliance members, Jura Nekis. Just as he comments that he'll have to deal with them himself, Natsu grabs hold of him and starts waving around him, demanding that he stop Nirvana. Klodoa eventually frees himself from Natsu's grasp, and then tells them of their plan to destroy Cait Shelter as they hold the power to seal Nirvana once more.

Just after Midnight's defeat, he begins whacking Natsu and Gray but peeps at Lucy before whacking her as well. With Midnight's defeat, and the six prayers now vanished, he yells out that a new personality of Brain will appear since all the Oración Seis members defeated and thus all the keys unlocked due to the nature of living link magic. A personality called "Zero" and one who loves to destroy. Zero himself enters and orders Klodoa to retreat before easily dealing with Natsu, Gray and Lucy.

Nirvana finally arrives at Cait Shelter's guild where Klodoa states to Zero that destroying Cait Shelter will make sure Nirvana can never be resealed. Zero however says that is "meaningless", promptly snapping and crushing Klodoa, and ordering Nirvana to fire.

Abilities
Magic Beam: Klodoa seems to be able to shift into a gun-like form where he can attack enemies. This was only briefly seen when Brain "shot" Cobra from behind.
