Fio is one of the main protagonists in the Metal Slug franchise. Fio is the only daughter of the ridiculously wealthy Italian Germi family. The Germi family has produced a long line of soldiers, so Fio’s father naturally wished his first born to be a healthy boy.
But his only child resulting from a difficult birth was a girl who soon became the apple of his eye. Since Fio’s mother could no have children, this marked the first time ever in the Germi’s long history that its heir be female. And because tradition dictated that the head of the Germi family must serve in the military, Fio soon enlisted in the Government Forces at the urgings of her father. Fio was lovingly raised by her parents, in stark contrast to the environment Eri faced, to become an urbane young lady.
She studied chiropractics, acupuncture, and moxibustion in college, and hopes to become a sports doctor in the future. She accompanied her comrades in every chapter of the series, preventing the world to be destroyed or conquered by a great variety of foes.
Same as normal, Blessed (The Super Devil possessed her and granted her its powers), Possibly Magic and Statistics Amplification (The Super Devil turns the handgun's bullets into cannon shells)
Attack Potency:Wall level physically (Characters on her level can kill soldiers with a single kick and tear them to shreds with a knife swing). Wall level to Small Building level with weapons (Can destroy tanks, helicopters and even large robots, giant monsters and heavily armored vehicles. Her weakest weapon, the handgun, takes only 9 shots to collapse a small building, while stronger weapons gradually increase in strength to the point of even dwarfing the total damage of said shots [more details can be found here, although numerical values and multipliers are not to be taken literally]. Can destroy large part of wooden buildings with a single rock throw. The laser gun can vaporizes human beings. The SV-001 releases such levels of force through self-destruction. Defeated Avatar of Evil)
Speed:Superhuman (Easily outruns soldiers) with Supersonic+ to possibly Hypersonicreactions/combat speed (Can dodge bullets, cannon shells, lasers on-foot and meteors while flying on space), Speed of Light attack speed with laser guns
Stamina:Superhuman (Can rush through and fight dozens of enemies while crossing or climbing environments like mountains, jungles and more. Can withstand prolonged battles with large machines, robots and other opponents that require many hits in order to be taken down)
Range: Standard melee range physically and with melee weapons. Tens to hundreds of meters with weapons and vehicles, possibly higher with the sniper rifle.
Handgun: A semi-automatic pistol that has unlimited ammo, but lacks the heavy firepower or high fire rate of other weapons. The handgun almost looks like the Enfield No.2 revolver.
Hatchet: Fio can use her hatchet for close-quarters combat when close to an enemy. Can kill humans in one strike and even hit multiple targets. Does more damage than a pistol shot.
Tonfa: Fio's second melee weapon. Just like the hatchet, it can kill humans in a single hit and deal more damage than the handgun.

Flame Shot: Fires a large flame blast, but has limited range and a slow fire rate. Flame waves travel in a upwards trajectory when fired horizontally with longer range. An upgraded version fires a larger flame wave and is powerful enough to damage armored vehicles.
Enemy Chaser: Fires small rockets that chase enemies. The rockets are slightly less powerful than the standard rocket launcher, but compensates with homing capability and increased ammo capacity.
Laser Gun: Fires a laser that can cut down groups of infantry in row and destroy large vehicles effectively. An upgraded version fires a laser that's 5 times as wide as the regular laser and is much more powerful. Can be fired diagonally as seen in Metal Slug 6.
Two Machine Guns: Fires two streams of machine gun bullets as opposed to the single stream. Is fired from two sub-machine guns instead of the AR-10. Starts with 350 ammo, but is used twice as fast since this weapon fires two guns.
Iron Lizard: Fires remote-controlled missile cars which travel along the ground until making contact with a target by exploding and releasing a large blast of blue flame. Is very effective against infantry and very weak against vehicles.
Drop Shot: Fires landmines which immediately drop and bounce forward until they hit a target or lose momentum and stop moving.
Super Grenade: Fires large RPGs rather than rockets. Upon contact, a large plume of fire is shot straight up to take out an enemy above. Is very effective against light-armored vehicles.
Zantetsu Sword: A upgrade that powers up Fio's hatchet, allowing her to launch energy waves in-front of her. Is powerful enough to kill large numbers of enemies, destroy incoming bullets and armored vehicles.
Thunder Shot: Fires blue lightning bolts that homes in onto enemies. Pierces through multiple enemies at once, making it a very useful weapon for getting enemies in a line. Starts with 20 rounds.
Sniper Rifle: Does fair amount of damage and has an extreme projectile range. A scope is provided.
Fire Bomb: Essentially molotov cocktails, which can cause flames over a large area and burn shielded enemies on contact.

Monolith: When thrown, shoots a beam into space and then brings down a big tablet, crushing any tanks or people under it.
Smoke Bomb: When thrown, produces a large wide screen of smoke that blinds enemies when they're in. Fio can also use these to sneak right past them.
Thunder Cloud: An artificial thunder cloud loaded with negative electromagnetic energy. The cloud will hover over the nearest target and zap it with lightning bolts until all its energy is used.
Mobile Satellite: A small, hovering remote control device resembling a satellite, armed with a rapid-fire ion cannon. It tracks down any possible target and discharges ion bolts continuously on them until they're defeated. Once its battery runs dry (200 ion bolts and it runs down) the satellite will fall and explode.
Snowball: A simple snowball. Throwing it will place a mini snowman on the ground that will block a person inside it should they touch it.

Transformations:
Fat
Mummy
Zombie
Monkey
Super Devil
1/5
Fat: After eating too much food, Fio will become fat. All of Fio's weapons will increase in size and change into a more comical appearance. This transformation increases Fio's firepower, but slows down her movements. The effects wear off after some time, or by collecting Diet Food.
Mummy: If hit by smoke breathed by mummies, or other specific and related attacks, Fio will turn into a mummy. As a mummy, Fio moves slower and can only use the handgun and regular grenades, suffering from a delay before throwing them. Sometimes, instead of a grenade, Fio will toss her own head, which has the same explosive effects and regrows immediately. The mummy form compensates for slow speed and a short jump delay with increased jump height and longer air time. This form can only be cured by a potion.
Zombie: When hit by a zombie's organic matter, Fio turns into a zombie. This transformation includes being restricted to her default handgun, and reduced movement speed, as well as a small hop instead of a jump. In turn, this form grants an enhanced durability. However, instead of using grenades, Fio will unleash a bloody, giant, vomit laser which can kill most enemies instantly and deal massive damage towards stronger ones. The transformation can be ended by picking up a med-kit.
Monkey: Getting hit by a de-evolution bullet will turn Fio into a small monkey. The monkey form has exceptional jumping ability, but reduced ground speed, and restricts Fio to using a small Uzi. Fio can also grab and climb across rails along the ceiling. This form can be cured by collecting a serum.
Super Devil: The Super Devil is an unknown entity who holds great strength and mysterious powers. It is a benevolent entity, and is able to possess soldiers and lend them its power. When possessed by the Super Devil, a soldier has green skin, glowing red eyes, and a more violent personality, but still retains its mind. The Super Devil turns the handgun's bullets into powerful cannon shells without delay and grants a special Mobile Satellite, which fires quick and infinite bolts.
Intelligence: High (Fio is an experienced soldier, who quickly climbed the ranks of the army and became Master Sergeant in the Special Ops Squad SPARROWS. She is regarded as a cunning individual by her friends and even enemies like Oguma. Alongside her comrades, she foiled Morden's coup d'etat during the second Modern War. She participated in special missions in different parts of the world and fought against many different enemies, ranging from soldiers, aliens and monsters. She's consistently able to defeat huge opponents that would take a single hit to kill her. Was able to use the computer of the alien mothership "Rugname" with ease. In one occasion, she boarded and conquered a battleship of the Rebel Army all alone. Among her hobbies and skills there are cooking, dancing, chiropractic, acupunture and moxibustion)
Weaknesses: Firearms' ammo are limited (except a handgun). Mummy/zombie form has terrible mobility.
