So if you insist, maybe you can tell Bandai to change their english website?
it reads as Nataku Gundam, but its only a nick name.
A middle ground answer is that they're for the most part redesigns of the second generation of Gundam Wing mobile suits, they're essentially the same mobile suits aside from cosmetic differences and Katoki's changes (although debatable with Wing Gundam Zero Custom more than any other since the redesign is so extensive, though the series never explains how such modifications came to be between the end of Wing's TV arc and the Endless Waltz OVA). Basically, they just wanted Katoki involved and some holes in the plot resulted.
But to use that as an example, it's only called Wing Gundam Zero Custom on model kits/toys/etc., since in the canon universe it's essentially still Wing Gundam Zero. Just like Altron and Nataku are the same, regardless of model kit/toy terms used to avoid confusion, and Wufei's nickname for the suit. Just trying to help and share what I know. D:
