Ok, I saw the trailer and I wasn't expecting Ansem and Xemnas to KHIII. But their in KH3 I want know how Aqua will react when she see Xemnas for the first time, will Aqua see Xemnas as Terra or Xehanort, if she sees Xemnas as Terra will Aqua hesitate trying to fight Xemnas, I like to know what you think.

I'm sure there is some cringy fanfic of how Aqua feels about Xemnas. All it takes is a little research

All I know is that when Aqua sees Xemnas, she'll definitely have mixed feelings, because she'll definitely see Terra when she sees him! It's gonna be a tense situation, mind you!

It would be like... "OH TERRA HELLOOOOO!*punched* OOH OH AH OOWW. WHAT I DO TO YOU?"

 

Foreshadow anyone?

Xemnas is Terra-Xehanort aged 10 years with white hair and orange eyes essentially, so yeah, I don't see why Aqua wouldn't see it as Terra. That'd be very interesting to see her react to Terra in his 30s.
