#1 Asuka

Asuka made a big impact even on the Independent scene, wrestling under ring name Kenta where she won many championships. But, the impact she made inside WWE ring is unforgettable. From being the longest reigning NXT Women's Champion(523 days) to winning the inaugural Women's Royal Rumble match, she has been incredible.
Asuka challenged Charlotte after winning the inaugural Women's Royal Rumble. Although the match was a classic, it hurt Asuka's credibility as her loss resulted in her streak being broken when she tapped out to Charlotte and the record became 267-1.
She was never the same. Although she got two title opportunities, she was defeated by Carmella which recorded her first pinfall loss. Carmella cannot even wrestle and WWE booked her to beat Asuka. It is disappointing.
This means that WWE has lost all its interest in Asuka and we might not see her become champion for a long time. Also, she is currently 36 and her career might be over in a few years. Let us see what WWE does with her later.
