Pierce Harrington was the obnoxious, rich neighbor of Mr. Davenport who, along with his son Clayton, only appears in the episode, The Bionic 500.


Pierce in The Bionic 500


Pierce is an ultra-rich man (even richer than Mr. Davenport) Ever since he moved to the neighborhood, he has been driving his car on Mr. Davenport's property all night, disturbing  AdamBreeChase, Leo, and Donald from their sleep. When he challenged Davenport to a stock-car race in which the loser would have to give up the deed to their homes, he hired Joey Logano to race for him. Later, it was revealed that he paid Davenport's pit crew to sabotage his stock-car. Then when Joey quit the race because he doesn't work for cheaters, Pierce was left to finish the race himself. However he lost the race, meaning he and his son must now move.


Pierce is shown to be arrogant and cocky (even more than Donald). Pierce also posses a big ego saying that his house casts a shadow over Donald's existence. He seems to think that money is everything.


  • Pierce is said to be so rich that when he showed his balance to the others, he had to slide the screen three times to show so many 0's.
