Warning: spoilers ahead for Future State: Superman of Metropolis #1!
In DC Comics' new Future State event, a New Superman has risen in the absence of the original Man of Steel, but Jon Kent might not be able to measure up to his father purely due to his genetics. DC has confirmed in Future State: Superman of Metropolis #1 that Jon Kent is not actually a true and pure Kryptonian, and more importantly that he has a unique biology which comes with its own advantages and disadvantages.
Metropolis is not doing so well in DC's future, and Lex Luthor and the original Superman have both been sent out among the stars. While Luthor was pushed out by the company known as Trojan and ventured out to run his own planet, Clark Kent was banished by Earth entirely and was forced to be the Man of Steel in space, leaving his son Jon to take over protecting Metropolis along with Supergirl. Now, Trojan has used its nanotechnology to turn several of the city's citizens into rioting zealots, forcing the intervention of the U.S. military. Meanwhile, the offspring of Brainiac known as Brain Cells is taking advantage of the conflict by connecting with the zealots and citizens, manipulating them for its own ends.
While the new Superman has finally determined to take the fight to Brain Cells and end the hive-mind once and for all, Brain Cells is far from impressed. The spawn of one of the original Superman's greatest foes instills doubt in the son of Superman, questioning his worthiness and ability to keep Metropolis safe considering that Jon is not a pure Kryptonian like his father or Supegirl. "You are not your father, Jonathan," Brain Cells observes. "You're human with just enough Kryptonian blood to make you interesting."
While not being truly Kryptonian is considered a weakness by Brain Cells, it's not necessarily a bad thing, since it also gives Jon certain immunities. While Brain Cells is able to use Nirodhium to influence and corrupt Supergirl to fight Jon, the element only affects Kryptonians, and Jon remains unaffected due to his human genetics. Not only that, but other stories have shown Jon does have the potential to become stronger than his father, suggesting that being a true child of two worlds will work in his favor more often than it poses a problem, even if Brain Cells does try to convince him of the opposite.
All in all, the symmetry that's now been created between Clark Kent and his son Jon is pretty impressive. The Legion of Super-Heroes recently revealed that Jon helps create the New Krypton of the 31st Century, creating a line through Kal-El, the Kryptonian who was embraced by Earth, through Jon Kent, the human hero who rebirthed Kryptonian culture, all while maintaining the theme of how these heroes' rich heritages make them stronger. Even if he is more human than Kryptonian, Jon Kent is more than worthy to be the next Man of Steel, so here's hoping that Jon will be able to gain the confidence he needs about his place in the Superman legacy going forward in DC's Future State.
