Mimic

 is a Caster Type Magic used by Kurohebi.

Description
A Magic which allows its user to mimic another Mage's Magic and use it as if it was his own. This form of Magic appears to be quite peculiar, with even Fairy Tail's founder Mavis Vermilion, a spirit with tens of years of experience on her back, remarking on its rarity. The specific mechanics behind Mimicry are as of yet unknown, it's unconfirmed what the user has to do in order to copy other's Magic or how many types of Magic he can have at his disposal at a given time.
