The world's most dominant female fighter is set to join the UFC at last.

On Monday, the organization announced that Cristiane "Cyborg" Justino will make her Octagon debut against Leslie Smith in a 140-pound catchweight bout at UFC 198 on May 14 in Curitiba, Brazil.

The reigning Invicta FC featherweight champion, Justino has gone undefeated in 16 straight contests. During that stretch, she has eight knockouts in the first round and only two opponents have gone the distance with her.

Both Invicta and the UFC are properties of Zuffa LLC, so it's long been speculated that Justino would make the jump to the big show, whether to face rival Ronda Rousey or one of the other top women's bantamweights. However, the UFC does not have a 145-pound division and making the 135-pound bantamweight limit would be extraordinarily difficult for Justino.

Smith is a former Invicta FC contender at 125 pounds, but she's had mixed results in the UFC so far, going 2-2 in four bantamweight contests. She recently defeated Rin Nakai via unanimous decision at UFC Fight Night 85.
