Perche is a new unit introduced in Metal Slug Attack. She debuts in the "Hero of Justice" Extra Ops.
Perche is a soldier of the Regular Army. She has a great passion for justice and as such was chosen by the army for the Metal Device Project. Even in her sleep, Perche sleep talks about being the hero.
Initially, entering the Metal Device Project just meant wearing the suit, much for her disdain. Perche spent most of her time doing janitorial work with greater speeds. It is not until Marco sent a request that she became ecstatic about finally doing some heroic work.
The Metal Device Project is an effort from the Regular Army as the next generation of weapons. Using the muscle tissue of a Super Devil, the Metal Device gives the pilot heavy durability with the benefit of human mobility. By calling on a wrist communicator, an ammo box flies in and attaches to the pilot's back giving them stronger firepower. As it's currently a prototype, the Metal Device is attached to the pilot's nervous system, and a few is able to wear it.
- Legion Gun: A beefed version of a Gatling gun.
- Gae Bulg Piercer: The pilot first calls for an ammo box. The Legion Gun's shots turn into piercers. The ammo box has large missiles. Using these causes the box to fly away from the pilot.
