AZ was a simple man, who befriended a Floette. They both fought in a war 3000 years ago, but Floette died. The man crafted a machine to revive Floette, but was enraged at the world and transformed the machine into the Ultimate Weapon. The world was destroyed and Floette, after learning that many died so she could live, left and abandoned AZ.
None of Floette's moves are known.
