Kim, who won gold in the men's team event on Saturday, was tipped to vie with his compatriots for the individual title but was devastated after succumbing to a 6-2 loss on a breezy afternoon at the Sambodromo.
Ega Agatha, a 24-year-old from Surabaya in eastern Java province, lost the opening set but stunned 24-year-old Kim in the next three, slamming the door shut with two brilliant shots that landed flush in the gold target for two perfect scores.
As a modest crowd in the terraces roared, Kim slumped with his head down while his team mates looked on in dismay.
Ega Agatha flashed a huge grin and high-fived his coach after setting up a match with Italy's Mauro Nespoli in the third round.
