When Franky was young, he was thrown off his parents pirate ship and out into the ocean to die. However, he was lucky enough to be saved by a famous Shipwright named Tom (Tom was also the shipwright who constructed Gold Roger's ship, the Oro Jackson). Tom took Franky into his home, where there, Franky met Tom's assistant, Iceburg. While with Tom, he learned a lot of shipbuilding, but most of his concentration and time went towards creating war ships used to fight giant sea-kings. He named these creations, Battle Franky.  However, Franky's life was turned upside down when Tom was put on trial for building Gold Roger's pirate ship. However, Tom was able to convince everyone that he could build a train that could travel across the sea ( This would primarily be used for trade. ), the Puffing Tom. So his punishment was subdued and put off until Tom finished the train. Tom's plan was that he hoped his sentence would be swayed after creating such a gift to Water 7, the island they were on.  Fourteen long years passed by, and Tom's sentence was going to be swayed. However, this changed. Spandam, the CP9 leader, was after the plans of an antient weapon, Pluton, for the World Government. Spandam was aware that Tom had these blueprints, so he used Franky's Battle Franky ships and attacked Water 7. Everyone there was unaware that Spandam had done this, all of them thinking that it was Franky, Tom's apprentice. So in this sudden attack, Tom was sentenced to death. Franky, outraged, tried to stop the Puffing Tom, the train he helped create, which was taking Tom away to be executed. Franky was completely run over by the train, terribly injured. He was announced dead. However, Franky survived the encounter with the ship, and rebult himself using spare ship parts.  As time passed, Franky was able to put together an underworld group of people, the Franky Family, a bounty hunting group and a ship dismantler group. After he had been in business with the Franky Family, he went to Iceburg to discover he had the blueprints of Pluton that Tom left him. Surprisingly, Iceburg gave Tom the blueprints for safe keeping. Four years later, a group of pirates known as the Straw Hat Pirates, came to shore on Water 7. The Franky Family mugged Usopp and taking all of the money they had gotten from Skyepei. After Luffy and the others discovered what happened, they went to the Franky House, the main headquarters of the Franky Family, and destroyed it completely. When Franky discovered what happened, he went and got in a fight with Luffy, wanting revenge, but their fight stopped abruptly when the townspeople through the blame of Iceburgs near assisination on the Straw Hat Pirates. Franky then went back to Usopp, kidnapping him and taking him to an underground base where Tom used to work. Franky's plan was that the other strawhats would come, so that he could take revenge. However, since Usopp was no longer with the Strawhats, this plan was futile. Suddenly, Lucci, Kaku, Blueno, and Kalifa, CP9 members, came to the underground base, taking Franky and Usopp, heading to the government base, Ennies Lobby, to turn Franky into the government and retrieve the plans of Pluton. They traveled toward Ennies Lobby via Puffing Tom, and although Franky was able to escape, he was captured again later. During this time, at Ennies Lobby, Franky took out the Blueprints of Pluton, and burned them right in the face of the CP9 members, and Spandam as well. After this, Franky joined with the Strawhat crew, taking on Ennies Lobby. He was placed against Fukurou, a CP9 agent, but, after some struggle, beat him. After a long trail of events, CP9 was finally defeated, and Franky headed back to Water 7 with the Straw Hats. In the latest chapter, the Franky Family has asked Luffy to take Franky into his crew since he recieved a bounty.
