Here is the biography of Cristiane "Cyborg" Santos:
Cristiane Justino Venancio, known professionally as Cristiane "Cyborg" Santos, was born in July 1985 in Curitiba, Brazil. She is a mixed martial artist and former Strikeforce Women's Featherweight World Champion.
Cyborg's early life was marked by a strong athletic background, competing in high school handball championships. After being approached by Rudimar Fedrigo, the founder and head coach of Chute Boxe Academy, she began training in combat sports, eventually adopting the nickname "Cyborg" in 2005.
Cyborg's professional MMA career began in 2005, and she quickly gained recognition for her aggressive fighting style and size. She won her first fight against Eric Paes, but suffered a loss to Vanessa Porto in her second bout. However, she rebounded with three consecutive first-round victories over Chris Schroeder, Elaine Santiago, and Marise Vitoria.
In 2008, Cyborg returned to action in the United States, defeating Shayna Andrea Baszler via TKO in the second round. She went on to win unanimously over Yoko Takahashi and then signed with Strikeforce, where she won the Women's Featherweight World Championship by defeating Gina Carano in the first round via technical knockout.
Cyborg successfully defended her title against Marloes Coenen at Strikeforce: Miami, but then suffered an injury that forced her to withdraw from her next title defense. She eventually returned to competition, defeating Jan Finney and Hiroko Yamanaka via knockout.
However, in 2012, Cyborg tested positive for banned substances and was suspended for a year, fined $2,500, and stripped of her title. After her suspension, she signed with Invicta Fighting Championships, where she defeated Fiona Muxlow and Marloes Coenen to become the inaugural Invicta FC Featherweight World Champion.
Throughout her career, Cyborg has been known for her aggressive fighting style, powerful striking, and formidable grappling skills. She is widely considered one of the greatest female mixed martial artists of all time.
