#2 Asuka

Asuka could realistically be dubbed the mother of NXT, as she is the first female talent to dominate the women's division, and remarkably carried an undefeated streak over to the WWE main roster.
The former NXT Women's Champion is the only female in brand history to leave NXT as the reigning Champion, and she never lost the title upon leaving the brand.

Once she made her main roster debut, Asuka skyrocketed to the top of the Women's division, and her undefeated streak culminated in a WrestleMania match against Charlotte Flair. Flair was able to end the historic streak, and Asuka has not been the same since the loss.
Asuka is currently paired up with Kairi Sane as The Kabuki Warriors, but the tag team has been used sparingly on WWE TV and seems directionless.
Under Triple H's tutelage, Asuka was a major player in NXT and was a big star, and a return to the Yellow and Black brand could help not only the former Women's Champion but could help boost the division in NXT as well.
Shayna Baszler, the current dominator of the NXT Women's division, needs a credible challenger, and Asuka could be the opponent Baszler is waiting for.
