Gymnastics: Simone Biles returns to World Championships, creates history with dangerous new skill

Olympic champion Simone Biles has made even more history while competing at the Gymnastics World Championships in Antwerp, Belgium.   

It's her first international meet since pulling out of the Tokyo Olympics, and she's back with a dangerous double-pike.

Biles has a list of records almost as dizzying as her aerial routines. But her latest claim to the gymnastics hall of fame has to be seen to be believed, and even then you need to watch it a few times. 

The 26-year-old chose the World Championships in Belgium to brave the most difficult vault in women's gymnastics and became the first to pull it off.

The Yurchenko double-pike vault will now be known as 'The Biles' - the fifth skill to be named after her.

It's so dangerous, Biles accepted an automatic half-point deduction so her coach could stand on the mat to intervene if necessary.

"She's a gem, man," said Canadian gold medal winner Kyle Shewfelt. "The entire gym stops when she is competing.

"You can feel a pin drop in that gym. She is what gymnastics needs.

"We have to do everything we can do to keep her safe. We should not be penalising her."

The competition marks a grand return to the world stage for Biles after she pulled out of the Tokyo Olympics due to the twisties - a mental block where gymnasts lose their sense of space in the air.

"I say put mental health first," Biles said at the time. "Otherwise, you're not going to enjoy your sport or succeed."

Already the most decorated gymnast in history, Biles is now also the oldest American woman to compete at Worlds.

The greatest of all time, just keeps getting greater.
