I get that Tocsax having an "X" name is supposed to brand him as a Nobody, but it does raise a bit of a question. In Canon KH, Xemnas used "X" in all the Organization members' names as a reference to the X-Blade. Is that also the case for Tocsax? Because if not, the presence of the X is a bit confusing.

It's the case for Tocsax; note that Leo the Second Mathematician (the Big Bad) doesn't have an X in his name, but yes, he does sprinkle in references to the X-Blade here and there. Also, 'x' is a component in Algebra.
