Nikki Bella may be counting down the minutes until midnight, Sept. 15, when she becomes the longest-reigning Divas Champion of all time, but her unprecedented tenure won’t be safe for long.

Waiting just around the corner for her at Night of Champions on Sept. 20, will be a challenger who has already made the Fearless Diva tap out once before: Charlotte.

The second-generation grappler earned the title opportunity when she defeated Brie Bella on the Aug. 31 Raw, besting PCB teammates Paige and Becky Lynch in a No. 1 Contender’s Beat the Clock Challenge. Now, Charlotte — whose illustrious 258-day NXT Women’s Championship reign indirectly helped lay the groundwork for WWE’s Divas Revolution — will receive her first crack at the butterfly-emblazoned title.

While the emergence of Charlotte, Becky and Team B.A.D.’s Sasha Banks has taken the WWE Universe by storm, Nikki has argued all along that she deserves the credit for the Divas Revolution. Evolving into a hard-nosed competitor known for forearming Divas into dust and wrecking spines with her Rack Attack, Nikki has maintained an unshakable grip on the division, downing everyone from Paige to Naomi to AJ Lee.

Yet, in Charlotte, has Nikki met her match? The daughter of WWE Hall of Famer Ric Flair, the No. 1 contender has been all but unstoppable since debuting in WWE. Perhaps her most impressive feat since arriving in WWE was a submission victory over Nikki in tag team action, when she made the champion quit to her Figure-Eight Leglock.

Can Charlotte achieve the same result in singles action at Night of Champions? Or will Nikki extend her historic reign even further? Watch the revolution enter a new phase — and possibly gain a new queen — when Night of Champions airs live Sunday, Sept. 20, only on the award-winning WWE Network!
