Lee Pearson was unsuccessful in his bid to win an 11th Paralympic Games gold medal.
The 38-year-old from Staffordshire was beaten into third place by Grade Ib freestyle winner, Austrian Pepo Puch, while Finland's Katja Karjalainen won silver.
Pearson had never been beaten in three successive Paralympics before London, winning nine gold medals, but his score of 74.200% aboard Gentleman was not enough, and he won bronze.
He picked up a 10th gold in Saturday's team competition, but his quest to join former wheelchair athlete Baroness Tanni Grey-Thompson and swimmer David Roberts on 11 golds will now have to wait until Rio 2016.
Pearson collected silver in Saturday's individual championship when Australian Joann Formosa defeated him, and Pepe and Karjalainen followed suit, with Puch winning by an emphatic margin of almost five per cent.
Pearson, though, appeared to be marked incredibly harshly by British judge Sarah Rodger, who awarded him only 65.250% for his James Bond-themed musical routine.
Rodger's mark compared with that of her fellow judge, Argentine Lilian Iannone, who gave Pearson 78.250%. The marks of all five judges are averaged out to give the final score.
