[Invincible] If Earth was so important to the Viltrumites, why didn't Nolan have more than one child? Heck, why did he stop at one family?

Later in the series, >!Other Vitrumites covertly come to earth and begin doing exactly that in order to build up their numbers. However, there's a huge range of outcomes in terms of how each individual Viltrumite goes about doing it. One of them gets so attached to his new wife that he refuses to take additional mates despite being under direct orders to do so, because he doesn't want to hurt her feelings. Another falls in love with *dozens* of women and starts families with all of them all over the world, like something out of a bad sitcom.!<

>!The throughline is that forming relationships with humans is the fastest way to steamroll the bastardry out of a standard issue Viltrumite and get them to stop caring about optimizing their takeover plans. Nolan is lying through his teeth about his disregard for Debbie, so it's very possible that his preferences were simply monogamous.!<
