Simone Biles clinches sixth Olympic gold at all-around final
In a tight race between Biles and Brazil's Rebeca Andrade, the American was surprisingly left trailing in third place after a flawed performance on the uneven bars.
But she was back on top after a solid performance on her next apparatus - the balance beam.
As she waited to perform last on the floor, she knew the gold would be hers if she avoided any unexpected slip-ups.
She executed an electrifying routine to secure the gold with a total of 59.131 points, just 1.199 points ahead of her Brazilian rival.
Andrade earned a second successive silver in the competition where each gymnast needs to show off their skills on all four women's apparatus.
Biles' teammate Sunisa Lee, the Tokyo all-around champion, fought back from a disappointing start on the vault to claim the bronze with 56.465 points.
Biles captured her second gold medal of the Paris Games, and her second all-around Olympic title after also winning the individual event in Rio in 2016. She also claimed the team gold earlier this week.
Biles, the most decorated gymnast of all-time, withdrew from the event in Tokyo to prioritise her mental health after suffering from the "twisties", a condition involving the temporary loss of spatial awareness that some gymnasts can experience when executing high-difficulty elements.
Her withdrawal caused concern among her vast fan base about whether she would ever set foot on the Olympic stage again.
