The American won the first of her five world all-around titles in 2013 at the age of 16 in Antwerp and has since become a household name after winning a record 25 worlds medals -- which includes a jaw-dropping 19 golds.
At 26, she will become not only the oldest American woman to compete at the worlds in over half a century but also the first woman to represent the U.S. at six artistic world championships when it kicks off on Saturday.
The U.S., Britain and Canada's women secured team quota spots last year while China, Japan and Britain secured men's quotas.
While the U.S. men are yet to secure qualification, the women are overwhelming favourites for top spot but Biles will have competition for the individual all-round gold.
The 2022 all-around champion Rebeca Andrade of Brazil, Olympic silver medallist in Tokyo, is a serious contender as is Biles's 21-year-old compatriot Shilese Jones, who took the silver at the worlds last year.
