OK, first of all: Max had two kids, IIRC. No more, no less. There is no "unnamed offspring". I don't know where you heard this.

Second, he never married Verdona. Most aliens probably don't even know what marriage is in the first place. And they could have been separated. After all, they met when he was in his 20's or something. Xylene came much later.

WHICH Ken? Gwen's brother or the first Ben 10,000's son? And why does it matter?
