The Imp is an enemy in Crisis Core -Final Fantasy VII-.
This enemy will mainly attack with Fire-based attacks, so equipping Blaze Armlet will help to maintain Zack's HP as it will enable Zack to convert Fire-based damage into HP. Hit it with Graviga, followed by Costly Punch or Assault Twister+. Beware of its Ultima spell, and either guard, have MBarrier active, or time a roll perfectly to avoid it!
imp is "a small, mischievous devil or sprite."An
