The Paralympic mascot is called Tom, named after the musician Tom Jobim.
The mascots' fictional backstories state that they were both born from the joy of Brazilians after it was announced that Rio would host the Games.
Who are some of the biggest stars?
Have you heard of Usain Bolt? Well, he's attempting to complete the 'triple triple' having won the 100m, 200m and 4x100m relay gold medals at both Beijing in 2008 and London in 2012.
Bolt's compatriot Shelly-Ann Fraser-Pryce is also seeking a third successive Olympic gold medal in the 100m, while American Allyson Felix is chasing more gold having already racked up four from Beijing and London.
Michael Phelps, having retired and now returned, is hoping to add more to his astonishing collection of 22 medals, 18 of which are gold, in swimming.
For Britain, Mo Farah will be looking to replicate his Olympic gold double from London in the 5,000m and 10,000m, while Bradley Wiggins is aiming to add a fifth Olympic gold medal to his collection.
What about Bolt's 'triple triple'?
Bolt exclusively told Eurosport earlier this year that securing an unprecedented Olympic ‘triple triple’ at this summer’s Games in Rio would be his greatest ever achievement.
"I have had a great career so far but I want to keep winning medals,” Bolt told Eurosport.
"As I always say I never focus on any one individual. I respect all my opponents but I know if I am fit and healthy that I will be very hard to beat.
" To win the triple triple would be my greatest achievement."
An ongoing outbreak of the mosquito-borne Zika virus has raised fears regarding its potential impact on athletes and visitors in Brazil. Many competitors have withdrawn from the Games as a result.
The sport most affected by the virus has been golf with International Golf Federation president Peter Dawson saying there has been "something of an overreaction" to Zika".
