Agapova, 23, finished veteran Hannah Cifers via rear-naked choke mid-way through the opening stanza at the UFC's Apex facility, having rocked her opponent with a massive head kick before following up to lock in a chokehold.

Agapova's display showcased her sharp striking skills and also the threat from her tall, rangey frame which will make her an awkward customer for many in the flyweight ranks.  

It also made a mark on social media, with the Kazakh being hailed for her "insanely impressive" performance – and branded a "killer." 

The win earned Agapova a $50,000 Performance of the Night bonus, and improved her streak of first-round finishes to three in a row. 

The Florida-based American Top Team fighter became the first person from Kazakhstan to step into the octagon, having signed with the UFC from the all-women's Invicta FC and previously appearing on Dana White's Contender Series – where she suffered a decision defeat to the gutsy Tracy Cortez.
