In case you forgot what a Cristiane "Cyborg" Santos fight looked like, she didn't take long to refresh your memory.

The former Strikeforce women's featherweight champion returned to action for her first fight since Dec. 2011 on Friday night at Invicta FC 5.

Santos looked like the "Cyborg" of old as she unleashed the onslaught from the outset in a first-round technical knockout victory over Fiona Muxlow (6-3) at the Ameristar Casino in Kansas City. Only the overmatched Australian's toughness helped her hang on for several minutes though Santos' ruthless beatdown before referee "Big" John McCarthy called off the fight at 3:46 of the opening round.

With the victory, Santos (11-1, 1 no-contest) sets up a fight with Marloes Coenen to determine the inaugural Invicta featherweight championship.

"I want to come back, I want to fight soon. I am very excited to fight Marloes Coenen she is a very good fighter. I want to do a good fight in July, I hope everyone comes and watches."

Santos defeated Coenen in a 2010 Strikeforce fight.
