#6 Alexa Bliss
Alexa Bliss is one of the top female wrestlers in WWE right now. Last year, she won the RAW Women's Championship at the Money In The Bank pay-per-view, by cashing in her contract on Nia Jax. Following that, she feuded with Ronda Rousey, who was angry at Bliss for stealing her opportunity, as 'The Goddess' had cashed in during the match between Rousey and Jax.
Although Alexa Bliss is currently an active superstar in WWE, she will not be a part of WWE SummerSlam this year, which is a big demotion for her. Bliss defended her RAW Women's Championship against Ronda Rousey in a singles match last year, which she lost.
Her last big opportunity was against Bayley at the Extreme Rules pay-per-view, where she fought alongside Nikki Cross for the SmackDown Women's Championship. However, The Goddess won't be in the spotlight this year, which is very unusual, judging by her run in WWE over the past couple of years.
Bliss has mostly been doing her "Moment Of Bliss" segment on RAW these days. She's seen walking backstage with Nikki Cross every week, which may lead to something big in the future. However, she won't be headlining the 'Biggest Party of the Summer'.
