I couldn't finish 'em. Looks like this's gonna get complicated.
Crescent Unit Primus is an enemy from Crisis Core -Final Fantasy VII-.
He uses the Anesthetic Missile attack and the Curaga spell that are shared among the Crescent Unit enemies, in addition to its own skill, AP Spiller, which inflicts major damage to Zack's AP. Despite his high HP, the player can simply hammer away at the enemy with regular attacks to defeat it if it is alone.
Primus is Latin for "first."
