New fanfiction sequel is here! Enjoy and be sure to review afterwards!
There was once an autistic boy whose name was Luke Carpenter. He was 19 years old student who lost his mother so his survival was depending on donations from authorities and his status of student. He didn't have real family that would care about him – his brother and father had their own problems and because of Luke's handicap they have given up on him. One day, Luke was visited by Autobots Wheeljack and Bumblebee who informed him that he needed to be transported to USA because their leader Optimus Prime said so.
Once Luke arrived and got to know everyone, he found out that Optimus Prime and all Autobots were all just fulfilling orders given to them from Pentagon. Optimus Prime was always caring Cybertronian and when he met Luke personally, he decided to take Luke under his protective wings once his duty was done. Luke accepted to work with American government but once he underwent the procedure in laboratories of Pentagon, he gained powers catalyzed by an AllSpark shard. He could control electricity and electronics around him came alive.
However, he discovered that death of his mother was neither natural cause nor accident. It was prepared plan of American government to get Luke into America because Luke's mother was standing between him and his duty. Enraged Luke murdered prime minister and many people from Pentagon. Optimus Prime managed to save Luke, but realized he and Autobots were betrayed by humans. In the meantime, Decepticons already knew about Luke and they all could see Optimus' soft spot for younglings.
Decepticons tried to assassinate or kidnap Luke many times and they always succeeded. Optimus Prime always regretted he couldn't do more. It appeared that with his compassion for the boy blinded his judgement. However weak he appeared, his courage and commitment to keep Luke safe and provide him happy life between Autobots always gave him strength to defeat Decepticons and save Luke from near death. Dinobots who met Luke weren't friendly in the first place, but once Grimlock, their leader saw abilities and strength of Optimus Prime in battle, they joined forces with them in battle against Decepticons.
With Luke's powers and government falling apart, Autobots and Dinobots changed location of their base. Arcee was expecting sparkling with Sideswipe as well and during their transport to the new base she gave birth to it. However, the sparkling was dead. Luke used his newly gained powers to revive it and miracle happened. After few months of Decepticons' inactivity it appeared that Luke with other Autobots will have calm Christmas. They spent calm dinner with their friends from N.E.S.T and that evening Optimus invited Luke to his office.
Luke was changing into Cybertronian thanks to the AllSpark shard within his body and Optimus was talking some sense into his mind since becoming Cybertronian would mean to lose his humanity. Luke reconsidered this option and decided to get the shard out. However, in that moment he was about to leave, a bounty hunter Lockdown attacked the base, Optimus' office exploded and Autobots were immobilized. Luke was captured for another six months. Before Luke was kidnapped, he and Optimus created bond which brought more troubles than use.
Optimus Prime suffered many injuries as he was connected with Luke and six months of torture by Decepticons destroyed every hope Luke had. Once Optimus Prime with all Autobots arrived and defeated all Decepticons, including Sentinel Prime, he was found anorectic and with revealed tissue without skin as a result of extraction of the AllSpark shard from his body. Physically and mentally destroyed Luke was transported back to the headquarters, however nothing was the same as before.
Luke has committed suicide one night and next day Ratchet read out a message from him to all Autobots at base where he explained his reasons and begged his friends to forget about him. Some Autobots took it better, some worse such as Bumblebee who really cared about Luke and wanted to protect him. Optimus Prime managed to survive the severing of his bond with Luke as the boy died, however it left him some scars on spark that he would never forget. Losing somebody dear to him changed Optimus Prime for good.
The following story is a sequel to Lifelong cross and it takes place five years after Luke's suicide. Although I haven't posted is as a crossover, it includes majority of features from anime: Fullmetal Alchemist. Those who watched this anime may know what to expect, those who don't know will find out.
