Just over 18 months ago, Amanda Nunes was ready to retire.
Brazil's 35-year-old double champion, widely regarded as the greatest ever women's mixed martial artist, had just lost the bantamweight title she held for more than five years to Julianna Pena in one of the biggest shocks in UFC history.
Nunes, who also holds the featherweight belt, is the only woman to ever hold two titles in the promotion and has beaten a host of former champions, including Cris Cyborg, Ronda Rousey and Valentina Shevchenko.
But as Nunes considered her future in the sport, she realised there was one thing missing from her glittering resume - to avenge a title defeat.
"Sometimes you are in a sad spot, like I was when I lost my belt, but the motivation came back," Nunes told BBC Sport.
"Obviously I didn't want to lose the belt, but that experience was interesting because I was sad - but it was a different type of sadness.
"It made me hungry like the beginning of my career. Everything came together again. Fire, hungry to train, to do good and gave me a second motivation."
Nunes made changes, leaving MMA academy American Top Team and setting up her own gym in Florida, before regaining her title in convincing fashion six months later to become the UFC's first two-time double champion.
On Saturday she will aim to draw on her newfound motivation when she defends the bantamweight title against Mexico's Irene Aldana at UFC 289 at Rogers Arena in Vancouver, Canada.
Part of Nunes is thankful for the defeat by Pena as it helped her break more records and prolong her career, setting up the fight with Aldana.
"When I lost the belt it made me better. I made a lot of adjustments in my life as a human and a fighter," said Nunes.
"I think even for the fans, too. The fans were like 'oh my god, now she's going to get the belt and become the champion again', so I feel like it was good because a lot of champions they lose the belt and are never able to get it again - they fall apart."
