Friday's triumph with a world record total of 233.41 points made her the first woman since American Michelle Kwan in 2001 to win successive world titles and enhanced her reputation as a skating phenomenon as she has now captured 10 titles in a row.
No one came close to ending that run on Friday as she romped to victory by 15.28 points over Canadian Kaetlyn Osmond.
The 17-year-old Russian also made it a clean sweep of world records as her free skate score of 154.40 was an all-time best.
Osmond and her team mate Gabrielle Daleman earned their first world medals by finishing second and third respectively.
