Augustus "Gus" Valentine is a supporting character in Beacon Pines. He is the Mayor of Beacon Pines and the son of Sharper Valentine.

Being put into the position of mayor by obligation and not by choice, he is fully aware of his incompetence in the role, especially when compared to Perennial Harvest's efficiency and how they often manage affairs fine without him, and so tries covering it up by attempting to seem busier than he really is. Because of this, he holds a lot of respect and trust towards William Kerr, and willingly defends even his more suspicious behavior due to what he’s done for him and Beacon Pines.

He greatly looks up to his father’s legacy, viewing him as the reason why the town is as successful as it was and taking many of his lessons and beliefs to heart. Despite this, he’s not fully blinded by his admiration, as he also blames the town’s decline on him.

When Perennial Harvest offered their assistance with the town (namely with The Foul Harvest's aftermath) after his father’s death, Gus was made mayor with assistance from his sister so that he can find out their “true intentions” while also maintaining his family’s legacy. The Cooking Minigame also reveals that his father had him work at an early age, and that they would have lunch together once a month (though Sharper was sometimes too busy to attend).

As he’s a different breed of dog to his father and sister, and how (according to Dawn[2]) there are rumors Sharper had children with multiple women, it’s possible he and Heiress share different mothers.
