Cris "Cyborg" Justino seems unbeatable in virtually every combat sports avenue she has tried.
And it's easy to see why.
She's gone unbeaten in MMA since 2005 and has developed the reputation of being the "baddest woman on the planet."
In this flashback video watch as Cyborg pins her opponent, Aline Ferreira who is competing in the 2016 Rio Olympics.
The match appears to have happened back in 2007 in Brazil, at that point Cyborg had competed in five MMA bouts and was no where near the household name she is now.
Ferreira is set to compete in Rio next week for the women's freestyle 75 kg.
Cyborg is set to make her second appearance in the octagon this September when she faces Lina Lansberg in the main event.
