Jimmy Hudson is the son of Wolverine. Wolverine fought alongside James Hudson in the Iraq war and entrusted James to take care of his newborn son. Jimmy's last name was changed from Howlett to Hudson to make the adoption official. The truth of Jimmy's origins would be kept in secret until Jimmy's high school days. Jimmy grew up not knowing that he was a mutant, but always felt different from other people. He denied the idea of being a mutant. Like Wolverine, Jimmy grew up with a taste for red haired women, lived life being reckless, and had a feral personality.
After the events of Ultimatum, Wolverine died and the United States government adopted anti-mutant policies. One night, while drag racing, Jimmy lost control and the car flipped over and exploded. Jimmy survived the explosion and was in severe pain, but he began to rapidly heal. His girlfriend was disgusted by and rebuked him.
The following day, Kitty Pryde arrived and handed a box of Wolverine's possessions to Jimmy. The box contained Wolverine's old Canadian dog tag, Timesweek's cover featuring Wolverine and the X-Men, and a lock of Jean Grey's hair. In a holographic message Wolverine appeared before Jimmy. Wolverine told Jimmy he was his son and to forget asking who his birth mother was, not to think about the past and focus on the future, respect the Hudsons for raising him, and learn to live with the choices he had made. Wolverine's final message was that he never regretted having Jimmy as a son.
Kitty theorized that Jimmy inherited Wolverine's abilities and encouraged him to try. After focusing hard, his bone claws painfully sheathed through his knuckles for the first time. Jimmy formed a metallic coating over his claws. After this, he mastered control of his claws.[1]
Jimmy sought out Jean Grey, who was using the alias of Karen Grant. She then proceeded to tag along with Jimmy's mission in recruiting mutants Derek Morgan and Liz Allan to their cause.

At Scotch Plains, New Jersey, Sabretooth surprised Jimmy and attacked him, wanting to kill him as a substitute for Wolverine. Sabertooth nearly landed a fatal blow when Quicksilver pulled him out. For some inexplicable reason, Jimmy couldn't use his regeneration powers due to Sabertooth's attack. Jean did her best to patch Jimmy up and then looked for some help. When Jimmy woke up, his wounds finally healed. However, he was shocked and confused that the Hulk was standing before him. Jean explained she made an arrangement with Banner/Hulk to become their enforcer and also give him some answers, specifically how he was found. Just then, Nick Fury appeared before them.
Jean explained to everyone that their group was called the Tomorrow People. Inspired by Wolverine, they were "Plan B" in the event that the X-Men had fallen. Fury would be their shadow-intel to help them be a step ahead of their pursuers, however, if they were to get caught, they were on their own.
Joining the X-Men
Jimmy left Ultimate X to search about his father past, only to be inprisoned by Stryker's forces. He later escaped along other mutants, and was seriously hurt. A mutant child brought him to the Morlocks Tunnels searching for help, there were the X-Men, who helped them.
Jimmy possesses similar mutant attributes to those of his father, Wolverine; though to what extent remains to be seen. Thus far, Hudson has demonstrated that he has inherited Wolverine's regenerative healing factor and retractable bone claws. Whether or not he will inherit his father's other abilities is currently unknown.
Regenerative Healing Factor: Like his father, Jimmy possesses a regenerative healing factor. His powers first appeared when Jimmy crashed his car and it exploded. Jimmy climbed out of the wreck burned and broken, but healed in a matter of seconds.
Retractable Claws: He has inherited Wolverine's famous three bone claws per hand. He can form a metallic substance around his claws at will. His claws were not synthetically bonded to adamantium like Wolverine, but covered in metallic substance secreted by his body immediately following the first time he extended his claws. The limits of the durability of his unique claws have yet to be demonstrated.
