Robocar Poli world

Jin is a girl who manages the Brooms Town Rescue Team.
Introduction
Genius inventor Jin has a wild imagination and is always confident, but when a report comes to the rescue team, she sends out a calm and quick signal. An all-around handywoman who builds and inspects all equipment at the rescue headquarters with excellent dexterity and scientific knowledge.[1]

Appearance
Jin appears to be in her late teens or early twenties, with fair skin, light brown eyes, and blonde hair in pigtail braids tied with red rubber bands and a red hairband. Her attire consists of an orange jumpsuit with white accents on the top, a golden wristwatch on her left wrist, a loose brown belt with a yellow clasp hanging below her waist, and shiny copper shoes. She is often seen wearing a red headset with a microphone, which is often used to take calls.

Personality
Jin is serious, but kind, caring, and sometimes even a bit of a jokester.

Jin cares a lot for the Rescue Team, as evidenced when she warned Helly not to go outside in a bad storm out of concern and fixed Roy's shoulder after it was badly injured.

She's shown to be a genius, as she has multiple inventions that have helped on more than one occasion.

However, she does tend to forget safety rules at times, sometimes leading her to get injured. A notable example is when she attempted to ride a unicycle despite her lack of experience and injured her leg.

Gender: Male
Helly is a member of the Brooms town rescue team.
Appearance
Helly is a helicopter consisting mostly of the colour green and a bit of white, as well as yellow kneecaps and yellow accents around his arms and wears blue goggles. On his head, he has a white propeller with his siren on top. On the middle of his head, the first letter of his name can be seen.
Helly is almost always in robot form unless he is flying because in his normal form he can't move, and also of the fact he is made for the sky.

Personality
Helly is the youngest member of the rescue team. His age is not yet confirmed, but he is coded as a minor/child. In one episode of Fire Safety With Roy, when Jin invented a device that beeps when a child comes near, Amber says: "Well a child walked into the area didn't he?" while Helly says: “I am not a child!”. This pretty much confirms he's a kid which is also the reason Helly can be childish and insecure. He is shown to be quite naïve as he can sometimes interpret things not the way they were meant. Aside the negative stuff, Helly is always eager to help others in need and would give it his all to bring them into safety again. Because he is in the sky, he has a better view of the area which is why Helly is usually the first one on scene.

Gender: female
Amber is a member of the Brooms town rescue team.

Appearance
Amber is an ambulance consisting only of the colors white and pink. She has a ribbon shaped siren. In the middle of her siren, she has the letter A on it which is the first letter of her name. However, in the beginning of the series a cross was shown instead.
In robot form, Amber is a nurse/paramedic who has a toolbox of medical supplies for both cars and people to help them with their injuries.

Personality
Amber is kind, sweet and speaks in a calm polite manner. Because of her personality everyone seems to like her. Amber is also the smartest member of the rescue team who's full of intelligence and good advice which is a powerful trait when it comes to complex rescues.

Gender: Male
Roy is a member of the Brooms town rescue team.
Appearance
Roy is a fire engine consisting mostly of the colour red and yellow and he also has a black helmet on top which has his siren on it as well as the first letter of his name in the middle,with the words "Fireman Rescue" on it . He's also a bit bigger in size compared to the other vehicles of the rescue team, his tires have some sort of red accessory on them.
In robot form, he's a firefighter and uses a hose which he can attach to himself to fight fires and uses other Rescue equipment as well. Even in his non robot form he still looks a bit like a firefighter since the helmet is a part of a firefighter uniform.

Personality
Roy is gentle and polite as well as courageous which is why everyone sees him as cool and amazing especially Benny. The kids in his spin-off series are also eager to learn about fire safety and are confident about their knowledge which also shows that he is liked by a lot of people. He is also the strongest member of the Rescue team which has helped the team on many occasions and strengthens the thought of him being cool. Although his age is not yet confirmed, he seems to be the oldest of the rescue team because of how mature he acts which is also a sign he has a lot of experience being a rescuer. In Thank You, Roy he's shown to be quite selfless as he ignores an injury and proceeds to help others but later his injury brings him into trouble.

Gender: Male
Pollie is the leader of the Brooms Town Rescue Squad.
Appearance
Pollie is a police car, primarily blue with a few white accents. His tires have yellow stars, reminiscent of the symbol on (some) police uniforms, and the first letter of his name is visible on the sides. He also has a different siren than the other members of the rescue squad.

In robot form, he is a police officer who can now use his hands to assist him in rescue operations and apprehend criminals.

Personality
As the leader of the Brooms Town Rescue Squad, he usually develops plans and directs the actions of his teammates. Paulie can be serious, but sometimes he likes to joke. He is caring, serious, kind, and everyone in Brooms Town knows him well. He is a hero, no matter what. He is also a friendly car, always warning people and cars to be careful.

Robocars are a type of living vehicle. Their unique feature is that they can transform from car to robot (even while moving), making them even more effective at rescuing people or other vehicles. Robocars are limited to: Poli, Roy, Amber, and Helly.
Roy is the tallest of the team.
Amber and Poli are of average height.
And Helly is the shortest. But they are all similar in that they are twice as tall in their robot form as in their vehicle form.

In Brooms Town, a small town with an experienced rescue team, accidents happen all the time: a car falls off a cliff in the rain, a car crashes, a child gets locked in a house on fire, and so on. But these incidents often don't end in death, as the rescue team arrives in time.
Most of the cars are animate. Their distinguishing feature (including the Robocars like Amber, Roy, Poli, and Helly) is their black eyes, located on the windshield (representing their cartoonish nature). However, most of the town's inhabitants are human.
