Rousey had Bella give the Armbar a touch and later held it on stage with several female superstars, except for one that could be her next challenger.
Nia Jax won the Women's Battle Royal earlier at the Nassau Veterans Memorial Coliseum in New York, after having eliminated Ember Moon for the last time and then immediately announced her intention to regain the RAW Women's Championship.
Jax, who won the right to compete for a women's title in the near future, said: "I wish the best of luck to Nikki Bella and Ronda Rousey … Whoever wins, I hope you enjoy the moment, because it will not last long" . "
After Rousey retained his title, The Irresistible Force was seen behind the scenes watching the champion celebrating from a television screen and seemed ready to claim his former title.
Jax and the UFC Hall of Fame member had a short rivalry last summer, shortly after the 31-year-old joined the WWE since the promotion of Dana White.
In fact, the first singles match of the UFC legend was against the real winner of the battle last June at the Money in the Bank Pay-Per-View.
However, her bout was marred in a controversy as the first UFC Women's Bantamweight Champion who won by disqualification following the interference of Alexa Bliss.
Bliss cashed her Money in the Bank briefcase, which she had won that night, and after mistreating "Rowdy," hit Jax with Twisted Bliss to regain the belt.
Rousey's enmity with The Irresistible Force came to an end when the MMA hero was slapped with a scheduled suspension and the former RAW Champion faced The Goddess with a stray effort in Extreme Rules.
However, evolution probably rekindled their rivalry, since the angle of The Baddest Woman on the Planet with Bella might not continue due to the reality star's business outside of professional wrestling.
Jax had problems the last time he faced Rousey, as he almost tapped with the Armbar before Bliss interfered in the last moments.
But the 34-year-old fighter is one of the most dangerous and tough superstars in the women's division, having eliminated people like Sasha Banks, Bayley and Charlotte Flair.
She won her first and only Women's RAW Championship at WrestleMania 34 last April at the Mercedes-Benz Superdome in New Orleans after defeating Bliss.
But Rousey stole the show that night in Louisiana when he put together possibly the most impressive ring debut of all time when he joined his fellow countryman Kurt Angle and destroyed Stephanie McMahon, as well as Triple H in a Match Team Team Match. .
She then went on to dominate the women's division and dethroned Bliss at SummerSlam last August, just four months after her fight arc, and became the first female athlete to win a major title in both WWE and UFC.
