UNEVEN BARS
My favorite has to obviously be Queen of the Uneven Bars Aliya Mustafina just being herself and taking what's hers, the Olympic gold to be precise. She successfully defended her gold on the same apparatus from London, which is an incredibly difficult feat in gymnastics. She also won Russia's only gold in gymnastics, just like she did in London. After struggling with injuries and low difficulty all quad and being counted out from the race to the Olympic gold, she brought her best to Rio, because that's what mattered. She actually ended up having the highest difficulty score out of all the contestants in the final, and since her execution is always impeccable, there was no stopping her.
