Charlie Watson

Charlie Watson is your average teenager going through some things — she's still recovering from the loss of her father, and the fact that her mother already has a new boyfriend isn't helping matters.

Charlie Watson, who is depressed by the death of her father and resentful of her mother Sally's relationship with her new boyfriend Ronald, finds the Beetle in a local scrapyard owned by her Uncle Hank, who gives it to her as an 18th-birthday present. When trying to start it, Charlie accidentally activates a homing signal that is detected by the Decepticons Shatter and Dropkick while they interrogate and kill Cliffjumper on one of Saturn's moons. The two Decepticons head to Earth, acquire human-made vehicle forms, and encounter Sector 7; pretending to be peacekeepers, they persuade the agency to help them capture B-127, despite Burns' objections. As Charlie attempts to fix the Beetle, it transforms into B-127, whom she befriends and names "Bumblebee". She then unknowingly unlocks a message from Optimus urging Bumblebee to defend Earth, which restores some of his memories. They are discovered by Charlie's neighbor Memo, who agrees to protect their secret, while Bumblebee learns to use his radio to communicate. While left alone one day, Bumblebee unintentionally destroys Charlie's home and causes an energy spike that attracts Sector 7's attention. When Sally blames Charlie for the havoc, Charlie has an emotional breakdown and finally expresses her pain over her father's death and leaves with Bumblebee and Memo, only to be intercepted by Sector 7 and the Decepticons. Bumblebee is then captured while Charlie and Memo are returning home. Charlie convinces her brother Otis to cover for her and Memo as they follow Burns to the Sector 7 outpost where Bumblebee is being held. While torturing Bumblebee, Shatter and Dropkick accidentally activate a message from Optimus and learn that the Autobots are coming to Earth. On a hill overlooking the Golden Gate Bridge, Charlie and Bumblebee said a tearful goodbye where the scout revealed his trans-scanning abilities and adopted a Camaro alternate mode, driving off to meet his fellow Autobots. Returning home, Charlie reunited with her family and Memo (though they weren't at holding hands level just yet). Inspired by her experience with Bumblebee, Charlie threw herself into working on the Corvette, eventually managing to restore it completely.
