On the website DeviantArt is an artist named LordKal-El is a fan who uses Faceapp to make images of what children of Clark Kent would look like but with other characters such as Mala (named Mal-El). Given them names: Ander Sullivan Clark's son by Chloe Sullivan, Klara Clark's daughter through the fake Kara, Wesley Atkins his son with Desiree Atkins, David Kent with Dawn Stiles, Sam with Zatanna, Brian with Jessie (from one of the episodes, there is another entitled Crazy Night, another called Unknown Identity, this one is a real fan), Clark and Gloria's child, Henry Kent Clark Kent's son with Lana Lang on Earth LK, a couple pictures of a daughter named Lara Baker or Lara Kent Baker a child with Alicia Baker, and a couple of pics one named Charlie Kent his son with Simone Chesterman and another son named Charlies Chesterman, and finally Ella and Marti the twin daughters of Clark and Lois. Plus a few crossover ones, such as with Gossip Girl having a son named Milo with Georgina Spark, Robert Kent with Cordelia Chase and Joyce Kent a daughter with Dawn Summers of Buffy the Vampire Slayer.

Remember these are all art, but they look very real.

Though I think he has a wild imagination.
