In his younger days, Videl was a pirate on board TheFlyingDeath along with Jecht and Trixxtal. When Protettore was being trained by Jecht, Videl would sometimes help out and show them how to maintain their strength and use it properly. He also trained most of the other crew members after Valerio's attack. But during the battle with the SKULLKRACKEN, the ship's captain, a fearless werewolf named Fenrir, ripped off Videl's left arm and left him for dead. Once the battle subsided, Jecht's crew was victorious, but at the price of Videl's arm and other casualties within the crew. After the crew disbanded and everyone went their separate ways, Videl returned to Spain. But after loosing his only love, his strength, he believed his life was worthless and slowly descended into depression. But things got better when he got married to a beautiful woman and had children of his own, effectively taking his mind off his dark past.
With the advancement in modern technology, Videl kept in touch with Jecht and Trixxtal, as well as the other surviving members of the pirate ship. Protettore still thinks of Videl as the strongest person he knows, so when he was made the Don of the Giordano mafia, he called Videl up and offered him a position. At first he was hesitant, because he still only had one arm and wasn't as strong as he used to be, but Tori had a solution. With a magician at his disposal, Tori had a mechanical arm made for Videl that was enhanced with magical power. It moves just like a normal arm and other than it's appearance, it's impossible to tell that its fake. With his new arm in place, Videl happily took up Protettore's offer and now works for him just like he had for Jecht. He handles business in other cities so he isn't at the moving fortress as much as the other Giordano members. Plus, he has a family to look after but he does drop by every now and again.
During his time with only one arm, Videl didn't stop his workouts, only revised them, so his right arm is so powerful that it can instantly kill a mortal man with one punch. He wears long sleeved shirts and gloves so no one can tell that his arm is mechanical. Also, his son works for Protettore as well.
