"I underestimated how kind the WWE universe would be," Rousey said in an interview with ESPN. "I thought any outsiders would be shunned. I was expecting to get shunned and to have to battle to be accepted. I worked my ass off to pay respect to what's so important to them, and hopefully they saw that tonight."
UFC president Dana White, who watched from ringside, told ESPN that he was happy for Rousey, saying she acted as a pioneer for women in mixed-martial arts,
"She accomplished everything she could at UFC," White said. "She has a title defense record that still isn't broken
“She has always loved professional wrestling, and now she gets to have a blast being a part of it. She will be great at anything she sets her mind to doing. I thought she was incredible tonight.”
