Transformers/Back to the Future

Following the events of the first film, Marty McFly finally returns home to Hill Valley in 1985, while Doc Brown departs with the DeLorean time machine. Meanwhile, the Autobots and Decepticons fought to control the time machine. Unexpedted for Marty, he wakes up in a dystopic present when the Decepticons killed most of the Autobots and successfully ruled the Earth, with Megatron having Biff Tannen as his second in command. Luckily, a time-traveling Cybertronian named Gigawatt qsearches Marty for help. After a tough and confusing encounter with Starscream, Marty decides trusting Gigawatt, who is joined by Skilz, another Cybertronian disguised as Marty's Hoverboard. The group meets the surviving Autobots lead by Rodimus Prime, who reveals that Doc was unintentionally responsible for the chain of events: when he traveled forward to the year 2015, he met Decepticon Rumble, who survived his encounter in 1985. Doc befriended Rumble, unaware of the latter's agenda. When the DeLorean was completely repaired, Rumble used it to travel back to 1974, using Biff to develop Energon supplies for Megatron's arrival. Gigawatt then revels he used to be a Decepticon, but after having enough with Megatron abusing and murdering other human workers, he trans-scanned the Delorean and escaped, but his flux capacitator was damaged in the process and in order to fix it, they need Doc, who is somewhere forming his own resistance.
