For a hero known for being a loner, famous razor-sharp claws, but it turns out they're the exception.
In fact, these children of Wolverine aren't typical examples of Logan’s bloodline, but the rare exceptions. Although one would suspect that a mutant of Wolverine’s power would his unique genetic code to all his children, most grow up to be ordinary people.
This surprising revelation was revealed in Wolverine: The End, a miniseries detailing Logan’s final days. Written by Paul Jenkins (the same man who fleshed out Logan’s backstory in Origin), and drawn by Claudio Castellini, the story followed an extremely elderly Logan who was still living in the Canadian wilderness. Now a grizzled old man suffering from arthritis, Wolverine still possesses diminished healing powers, allowing him to hunt and fight when needed.
In many ways, this Wolverine is very much like the elderly Logan showcased in celebrated film Logan. He’s even haunted by Charles Xavier, who talks through Logan and may or may not be the psychic ghost of the real Professor X. But Logan’s (relatively) low-key retirement is brought to an end when he attends Sabretooth’s funeral and gets drawn back into a plot that may or may not be related to his Weapon X days.
The mastermind behind the conspiracy turns out to be John Howlett, Wolverine’s secret brother who has a similar mutation to Logan that’s enabled him to survive throughout the decades. Driven mad by a forced incarceration in an asylum, John now seeks to destroy the world’s economy by bombing Nevada, which controls much of the world’s finances in this dystopian future. Hoping to bring Logan to his side, John offers more knowledge about Logan’s forgotten past and plays head games with him.
At one point, John even claims that Wolverine abandoned many of the children he fathered over the decades because he was ashamed that they were born without the X-gene and went on to live ordinary, mundane lives. John even tracked down a few of Wolverine’s children and revealed that one of them chose to become an ant instead of a superhero. Given the number of children John implies are out there after Wolverine's long time on Earth, it certainly seems like those with powers are the rare exception. Logan did not elaborate on any of John’s points, but a few scenes in the miniseries paint a potentially different story of Wolverine’s relationship with his “ordinary” offspring.
Early in the miniseries, readers are introduced to George, a man in his sixties who’s been delivering supplies to “Mr. Logan” since he was eleven years old. While Logan treats George with his trademark gruffness, he’s also surprisingly friendly with him and regularly calls him “son.” Considering that Logan usually calls his friends “bub” or “kid,” there’s actually a good chance that George is one of Wolverine’s human children, and Logan has chosen to watch over him from afar.
In the end, Logan leads George to one of his hidden fortunes, giving the old man more than enough money for a comfortable retirement. Rather than run off with the cash, George remains loyal to Wolverine, supplying him with some requested supplies and even helping him escape from some next-generation X-Men trying to bring Logan in. If George is one of Logan’s human children, his actions easily prove that while most of Wolverine’s kids might not be mutants, they all have the capacity for the same heroism and courage their father repeatedly shows!
