"Don't worry about me, I'm just fine." - Fio's pet phrase.
Fio is the only daughter of a wealthy Italian family. The Germi family was historically a military family, so of course Fio's father wished for the first child to be a strong son. However, following a difficult birth, her mother became unable to bear additional children. This was the first time in Germi history that the family had a female heir. Due to family tradition, she was required to become a soldier, so she was made to join the Government Forces. The complete opposite of Eri, Fio was raised by loving parents and possesses a quiet demeanor. She studied chiropractics and acupunture in university and is thinking of becoming a sports doctor in the future.
For a seasoned warrior, on occasion Fio will display an almost childlike naivete and exuberance. Her victory pose is a pure example, another example is her that her favorite metal slug vehicle, is the donkey, leaving the other members of the team thinking less of her, though she is a tough independent woman when it comes to her fierce battling, the soldiers always laugh until they are shot down by her mechanical donkey.
In Metal Slug 6 and Metal Slug 7, Fio is skilled with the special weapons. She already starts every mission equipped with a Heavy Machine Gun, and she gets more ammo for weapons and her weapons cause more damage.
She also awards 10,000 points for a Teddy Bear, double the normal points for that item.
Fio has brown/orange hair in a ponytail and has brown eyes. She wears glasses, tan vest with a white tanktop underneath, brown short shorts held by a belt, light brown knee pads, socks and brown army boots.

Days of Memories
Fio is one of the girls that can be dated in the second game of this dating sim series. Fio does not appear again in the sequels.
Fio is the fourth and final playable character in this game, where she is playable after completing the 8th mission. In this game, she first appeared in a cutscene where Allen O'Neil and an army of Di-Cokka's are attacking a Regular Army base in a desert. Fio and Eri tries to fight them off, only to get killed instantly by explosive missiles. Later on, a revived Fio reunites with Eri, Marco and Tarma in the middle of the Arctic sea using one of Morden's battle ships that she stole. Now reunited, Fio and her friends stage an assault to Morden's base where Marco commands Fio to keep the base secured.
Fio is a standard unit unlocked by completing Africa in World 1. Her close-range attack is a smack of her tonfa, her long-range is a single pistol shot, and her special is a single Rocket Launcher shot. A Christmas variant gives Fio stronger attacks caused by slight anger of a sortie interrupting her holidays. Saving Fio by rescuing all POWs reduces all units' production rate. Saving her zombie form increases AP gained from defeating enemy units.
Fio is a Normal unit unlocked by completing China in Standard Mode. Parts of Fio can be found in the MSP Crank, POW Shop, Normal Shops, and as a random drop in Elite 1-4. Her third skill replaces her pistol with the Rocket Laucher after she delpoys her special first. Her fourth skill gives all Regular Army units a mobility boost if placed on a deck. Fio has five variants: Everlasting Summer, Christmas, Lightning, Valentine, and Special.
- Everlasting Summer Fio (Super Rare) has her in beach clothes. She dons the Big Rocket Launcher that explodes into three mines. Her stronger firearms were formed by her slight peeveness by the Pirates interrupting her and Eri's vacation in the "Pirates Attack" Extra Ops.
- Christmas Fio (Super Rare) has her in a Santa dress with her hair down. When her fourth skill is unlocked, she shoots multiple rockets upwards that soon drop down on an angle at enemy units.
- Lightning Fio (Super Rare) has her in blue clothes. Her long-range attack has her Thunder Clouds hovering towards the closest enemy units. Her special is a randomly traveling shot from the Thunder Shot. These weapons were made for aquatic battles, like Fio's mission from the "Pirate's Ghost" Extra Ops. Fio is teamed up with Roberto Nicola for this mission.
- Valentine Fio (Rare) has her in pink cooking clothes with a different ponytail style. Her tonfa is replaced by a chocolate covered whisk. Her special is throwing healing chocolate boxes onto her allies. Fio is very picky on food, so the chocolates were made by her using the finest local ingredients.
- Special Fio (Rare) has her in dark blue clothes, piloting a red Slug Flyer. Her long-range attack is to fire a burst of vulcan fire towards a single targer. Her special is a burst of missiles. If the Flyer is shot down, Fio parachutes out carrying a Rocket Launcher.
- Fio for Liberty (Super Rare) has her in a dark purple latex bodysuit and fights with a mecha.
- Both she and Eri Kasamoto were the first women to be introduced in the heroes team (formerly composed only by the males Marco and Tarma), in Metal Slug 2.
- In Metal Slug 2 and 4, Fio has Eri's death scream.
- Fio has slightly different victory animations between games. Metal Slug 2 does not have her making a "V Sign", while Metal Slug 5 to XX skips the animation where she leans forward for a bit.
- One of her favorite drinks is Ice Tea (Queen Mary) and her Blood Type is O.
- She has been on certain recon missions with Leona Heidern, and they're good friends from that point.
- Fio has been one of the most notable characters in the series, the first being Marco.
- She, Red Eye, Clark, and Alisa are the only playable characters who wear a cap.
- There is an unused victory pose sprite animation found in Metal Slug 2 where she jumps up and down just like Eri for her victory pose. This animation, however, actually gets used in Metal Slug Attack when you use the Mystery Crank's "Medal Crank".
