Bill Dewey has balding dark-brown hair, and coral skin. He normally wears a light violet-gray coat with a white shirt underneath, a dark purple neck tie, gray-brown pants, black socks, and chocolate-brown shoes with dark purple stripes.
Bill Dewey displays some of the typical stereotypes of politicians: he believes his position affords him entitled privileges, he's overly concerned about money, he's distinguished in public but unconfident in private (especially when put under any pressure), etc. He likes to pretend that he has more importance, influence, and control over Beach City than he really does.
He refers to the town as "a magnet for disaster", which is a fair assessment as the locale is often the target of unnatural phenomena such as dangerous Corrupted Gems, destructive machines from space, and other disasters like the recession of the ocean or the falling debris from Peridot's spaceship. He's slightly incompetent at his job of managing the city (he pitifully tries to refill the ocean with a watering hose when it recedes), so he employs a "bread and circuses" political tactic to keep himself in the town's good favor. He believes it's his job to keep the citizens feeling calm and secure, so he often sets up various diversions and attractions such as the world's largest bowl of ice-cream ("Joking Victim"), a Summer Season welcoming speech ("Mirror Gem"), a New Year's Eve fireworks show ("Maximum Capacity"), and a statue of himself.
He visits It's A Wash to have his campaign vehicle cleaned in "Cat Fingers". He is upset when Steven sprays him during a hose fight and tells Greg to control his kid. Greg apologetically says the car wash was free, and Mayor Dewey seems satisfied.
In "Mirror Gem", Mayor Dewey is first seen driving on the boardwalk, which Steven happens to be walking on. After telling him to "go get run over somewhere else", Dewey drives to the ocean-side, where he makes a speech to the people of Beach City about the coming of summer. Unfortunately, his speech is full of double entendres, which Steven and the Mirror mock in order to make fart jokes. The audience is more entertained by Steven’s antics than the speech, leaving Dewey mildly put off.
He appears again in "Ocean Gem" on the beach and is panicked over the sudden disappearance of the ocean. He's seen grieving about the resulting damage that's likely to be dealt to the city tourist industry, as well as the likely end of his career. After Steven and his friends return the ocean, Dewey desperately yet thankfully embraces Steven as the rest of the townspeople celebrate his heroism.
He takes on a main role in "Political Power" after the Crystal Gems accidentally knock out all the power in the city with an EMP. Enlisting the help of Steven, he travels around the town assuring the citizens that everything will be fine and that the power will return that night. After the power doesn't return the citizens of Beach City turn on him for lying. He is quickly saved by Steven who encourages all of them to stay strong and to not turn on each other. He also gives Steven advice and explains to him the basis of politics, which, as he understands it, is making stuff up to ensure that the citizens of the town are kept happy and safe.
He returns again in "The Return" after being called by Steven, shown cowering behind a curtain in response to Peridot's ship. Steven calls on him to use his political powers to convince the citizens of Beach City to evacuate to keep them safe from the approaching threat. He is later seen driving around town with a new truck jingle urging the citizens to evacuate. After Steven is knocked out of Greg's truck from the airbag he is seen standing around with the rest of Beach City's Citizens making sure that Steven is not hurt.
He is seen unpacking inventory in the Abandoned Warehouse,and practices "acting cool" in front of Buck but always fails. He made a poster for "Bench City" (which was actually just a poster that says "Welcome to Beach City" re-written into "Welcome to Bench City" by Mayor Dewey in permanent marker.) He is rushed out of the Warehouse by Buck and is later seen again, Giving a speech about the bench that was positioned behind him. He is shot in the stomach with a t-shirt by Steven as his body guards and the whole crowd goes wild and runs in different directions as they see t-shirts randomly being shot out from nowhere.
He is Buck's father. According to Buck Dewey, his father was never overly affectionate to him. He also said he seemed more focused on his job as a mayor than his role as a parent. However, Bill acts very supportive towards his son and encourages him in his artistic endeavors and does not seem to mind his son's refusal to follow in his footsteps and become mayor one day. Even though Bill is busy with mayoral duties he clearly loves and trusts his son. Their relationship is further explored in the episode "Shirt Club". Buck is embarrassed by his dad at times but still cares enough to visit the new bench announcement, showing that despite the fact Buck can't stand his father, Bill still deeply loves his son.
In his first seen interaction with Steven, he was annoyed that Steven sprayed him with water. Since then, however, Dewey has repeatedly turned to Steven and the Crystal Gems in moments of crisis for the city. He was inredibly grateful to Steven when he returned the ocean in time for the summer tourist rush. Steven helped Mayor Dewey save face with the town when the power went and seems to have gained Dewey's direct phone number in the process. Steven believes Mayor Dewey sometimes lies to the townspeople because he loves them and wants to protect them.
Greg cleaned Dewey's campaign van in the episode "Cat Fingers". Mayor Dewey was happy to accept a free cleaning as compensation for getting sprayed with the hose by Steven.
General Residents of Beach City
Dewey believes that the citizens, whom he sometimes refers to as "the Boardies", of Beach City need to be coddled and distracted from the major issues of town. He knows that the city is a major site of unnatural activity and fears that if the people aren't kept calm they might riot (like in Ocean Town) or worse - not re-elect him.
Mayor Dewey does not have much interaction with the Gems, other than when major things happen to the town, such as a power outage or the ocean disappearing. He understands that the Gems have some connection to whatever unusual activity is happening to the town and is happy to let them take care of it. As the Gems live in Beach City, he tries to assert his authority over them in "Ocean Gem" by demanding they return the ocean.
Like most citizens of Beach City, he doesn't fully understand what the Crystal Gems are or what their relationship is with the Universe family. He knows they're Steven's caretakers and assumes they're his sisters. He does, however, appear to be attracted to Pearl as shown in "Political Power". He refers to Garnet as "the tall one", Amethyst as "the purple one", and Pearl, revealingly, as "the hot one". He then swoons and blushes when she appears by the door.
