When Iemitsu picked Yoshi over Fem-Tsuna, she never had a father figure and was mostly a Bothers-little-girl. But when her brother left with out a good-bye, she felt that her brother hate her and became alone. Nana saw this and sent Tsuna to her best friend and Tsuna Godmother June Darby and her 15-year-old son Jack. She and Jack acted liked brother and sister. After a year Jack and Tsuna accidental dragged into a out-of-this-world-war. She, jack and 2 other meet the Autobots. Ratchet became Tsuna guardian, to his dislike. But Ratchet warm-up to Tsuna over the years. She became good friends with Raf, Miko and the other autobots and Ex-Decepticons Knockout and Dreadwing. (Yes dreawing is alive in this story). When the war was over Tsuna had go back home to namimori. Soon her twin come back year later. What happens when Yoshi come home to a very smart Tsuna.

Fem-Tsuna Personality: It is a mixture of Ratchet and Knockout. She can be reckless like Wheeljack and Smokescreen. But acts like a good Leader like Optimus Prime. Like the saying All bark and no bite? She all bite and no bark.

Fem-Tsuna is a skilled motorcyclist (or will be) and learned mechanical/technical engineering from her time with Autobots (but mostly from Ratchet and Knockout), she can hack in to any technology (got it from Raf), and her hobbies are graphic design, photographer, painter, and inventor (it tends to explode on her like the WheelJack form Transformers g1). Because she explods things she became a little Wrecker. (like miko when she and Tsuna went with WheelJack to face hardshell) Like Miko with the Apex Armor, Tsuna can us the Phase Shifter. (Not amusing to Ratchet) Tsuna has a one of a kind I-phone made by Ratchet so she can call anyone without being tracked other lines.(only the autobots, jack, raf, miko and the ex-decepticons)

Outfits:

When she working on her Inventions she wears a short loose white (with a lil oil stains here and there) basketball shirt, showing her orange sports bar, black knee length shorts, sneakers, and orange goggles. (her mechanic outfit)

Her Namimori Middle School Uniform but with Orange Visors on top of her head (her school outfit)

On normal days she wears Speed metal and wild punk outfits with her orange visors. Like Miko but with Orange.

Optimus Prime: Teaches her about being brave and a good leader

Ratchet: Is a father figure to Tsuna (well he act more of a father like she was his own sparkling)

Arcee: teaches her not to let anyone push her around

Bulkhead: always gets into mess with her and miko, (to the dislike to ratchet)

Bumblebee: Like to play video games with her and Raf

Wheeljack: Like her like a little sister, and calls her a Little Wrecker

Smokescreen: Likes her like a little sister, gets in trouble a lot with her

Knockout: My not show it but cares for Tsuna (she was the first to welcome him to the Autobots) and nags at her outfite and choose different styles for her

Dreadwing: Somehow Tsuna saved him from being offline (she used her sky flames but doesn't know about it) and he became very loyal to Tsuna, like he use to for megatron. Dreadwing red optics changed to the color Orange.
