Nathan

Nathan is a boy, who is the son of Saniya and Alex. He is born sometime in the future. Although he doesn't exist in the real world, he has had factious portrayals in various games.

In the future
Nathan is made after Saniya and Alex have S Word, resulting in Saniya getting pregnant. This will (hopefully) happen after the two get M Worded. As he does not exist yet, it is unknown if he is younger or older than his siblings, including Lia. He is traditionally portrayed as having olive skin, due to his partial Indian ancestry.

In the Sims
In the Sims, Nathan is made in a similar fashion to real life. He is born of Saniya and Alex and a brother to Lia.

In Minecraft
In Minecraft, Nathan was born before Lia in the mountain house. He also had appeared in previous worlds, such as the tree-house world. Saniya then killed him for being "too ugly" which greatly upset Alex.

In the mountain house, Nathan grew up to become an adult, and later married a villager from a nearby village. She was brought with the help of Alex and Poopy.
