If Fio had managed to escape from the MECH at the beginning of the experiments and had run into Breakdown, avoiding death at the hands (or claws) of Airharchnid, Breakdown, seriously injured, managed to flee with the girl, but ended up being captured by the Autobots, believing that he had kidnapped her and having Fiorella in their base while they locate her home, see if the experimentation on her body affected her, how to reverse the damage and how to return (being a stressful matter for Fowler to discover that she is the daughter of one of his subordinates and knowing that MECH has her in their sights, almost having to transfer her and move her to Jasper with a temporary family while they make sure that no bot or human is targeted again).
Fio despite the terror of the kidnapping and the first impression of the Autobots; She's fascinated by everything around her, trying to take matters with optimism and forming a strong bond with Breakdown, while gradually becoming friends with the rest of the main team, to the point where they both officially join Team Prime (Breakdown had several clashes with Bulkhead, but they didn't work well together), Breakdown as part of the team's brute force, and Fio as a remote support, looking for weak points (physical or emotional).
As for Knockout, he was initially pleased to see Breakdown alive, but grew jealous that a real person had such a close friendship with him. Although Breakdown himself captured him to free him from his nemesis, he still ended up joining the Autobots, adding his own annoyance with the Cons… and also sympathizing with the human simply because of her good taste in vehicles. …It's basically a pair of Decepticon robots who switched sides because one of them adopted a teenage girl.
