So this question may have been asked along time ago but guyver xt is xt2 from Allen's fic right?

Yes. XT2 is the same person who took on a certain red being with wings when he first came to be.

One of the nice things about doing the re-write is I can make this clearer were it concerns XT. Dpending on his schedule Mike will also be inputting into this so how the character was handled in the GWOTG story itself when Allen was using the character will also be changed and not just a case of "Hello, I beat you up now as you're powerful!".
