Usain Bolt blitzed his way down the track to win in 9.63 seconds in the Olympic 100m.
Just a short while after "Blade Runner" Oscar Pistorius missed out on qualifying for the 400m final, Bolt silenced his doubters by breezing past the finish line in a time of 9.63 seconds, beating the Games record of 9.69 he set in Beijing four years ago.
Training partner Yohan Blake took the silver medal in Sunday night's final to make it a Jamaican one-two, a day before the Caribbean nation celebrates the 50th anniversary of independence from Britain.
Compatriot Shelly-Ann Fraser-Pryce got the party started on Saturday by retaining her women's 100m title.
Some had questioned whether Bolt had it in him to win a second successive gold in the blue riband sprint after suffering back problems, getting himself disqualified for a false start in last year's world championship and losing to Blake in the Jamaican trials.
But after an indifferent start, he blitzed his way down the track to win in 9.63 seconds, an Olympic record and the second fastest time ever behind his own world record of 9.58. The US's Justin Gatlin took bronze.
Bolt kissed the ground and then leant back and pointed to the sky in his trademark 'lightning bolt' salute before basking in adulation on a lap of honour, draped in the Jamaican flag.
"Some of you guys doubted me," the 25-year-old told reporters. "I just had to show the world I was the greatest.
"It means I'm one step closer to being a legend," said Bolt who will now bid to complete an unprecedented double-double by retaining his 200 title on Thursday.
