Mona

Mona (モナ Mona) is an Exceed from Edolas. Initially no different from a normal Exceed, Mona, behind the back of Faust, was experimented on to replicate the Magic Origin located within the body of an Exceed. Through this experiment, she was she she was given a 'human' form, to test the results of magic within the human body, as well as trying to create the ultimate weapon.

When the Anima was unleashed in Edolas during Fairy Tail's excursion to the alternate world, Mona, along with the rest of the Exceed - and others, like Jason LaHote - were taken away to Earth Land. Due to a slip in the time-space axis, she was sent 200 years ahead of the rest of her kind, and is currently living with Alucard.

Mona has a bond with Erytheia Ashmedai and, to a lesser extent, Leilah Ashmedai, one that resembles a master and pet, and only takes orders from them, vowing to keep them both safe from any harm. This naturally puts her in contention with Cybele, the primary caretaker of Leilah.
