Here's Ronda Rousey's badass comeback "Rocky" style montage -- complete with grueling workout sessions, full-speed wind sprints ... and a sick look at her mansion in the hills.
It's all part of the new promo for UFC 207 on Dec. 30 in Vegas -- and the message is clear ... Ronda has heard all the doubters and haters and CAN'T WAIT to prove 'em all wrong.
She's your problem now, Amanda Nunes.
(BTW, yeah that's G-Eazy on the track)
