What's yours is mine and what's mine is mine!
Gian is recognized by his large build (might partly be contributed by obesity), as well as his mean and aggressive behavior. He "rules" the neighborhood with force, often to the physical expense of other children, especially Nobita, who often resorts to asking Doraemon for gadgets to get even on him. He appears to be just as depending on Nobita as Nobita is to Doraemon as he constantly tells him what to do despite Nobita's protest. In addition, he has a tendency to rob things from other children, usually Suneo, who offers himself to be Gian's sidekick in most occasions.
Despite his flaws and big bully appearance, Gian is actually a good person inside and always helps his friends and is loyal to them when they are in trouble. The official US Doraemon website states that deep inside, Gian is just a simple guy with a big heart.
Gian's signature colour is orange and he is usually represented by it.
Gian has black hair and tan skin in all the versions of the franchise.
In the 1973 anime Gian had small eyes and wore a red T shirt with navy blue trousers and brown shoes.
In the 1979 anime, he wore an orange shirt with a yellow stripe, gray pants and blue shoes.
In the 2005 anime, he has smaller eyes, which now appear as black dots/balls, and usually wears a light orange shirt with a light red stripe, and brown pants with gray shoes.
Gian has realistic black hair and his black eyes are not like dots. He wears an orange t shirt and navy blue trousers.
Gian is known for his overconfidence in his terrible singing voice, though he considers himself to be a great singer. Singing is a prominent hobby of Gian, in which he thinks himself proficient. However, his singing is actually very appalling almost to the point where people often pass out upon hearing his singing. Nonetheless, he manages to "convince" the neighborhood to be his concert audience, and even force them into praising his singing. But in some episodes when his voice is recorded and he hears it, he denies it being his voice and threatens to beat up the person who sung his songs terribly. He regularly subjects the neighborhood children to horrendous singing recitals, which is sometimes combined with his equally bad homemade dinner and his atrocious fashion sense.
His favorite food is stuffed capsicum. He also frequently steals other children's toys and manga books under the pretext of "borrowing" them, unless the toy is damaged. This is why many fans considered Gian to be the antagonist of the series. However, he does not hesitate to help Nobita and his friends when they are in real trouble, which often occurs in the movies.
Several of the stories revolve around Nobita and his friends' efforts to avoid Gian's concerts, and several chapters summarize his friends efforts to avoid visiting Gian's house on his birthday because of his selfish nature. After reflecting on one event about his birthday, Gian thought of himself why he wasn't popular among his peers. After getting a lecture from Doraemon to see what an unruly character he is, Gian realizes that he should have been a better person and he begs Doraemon to give him another chance. However, things didn't go exactly as planned when Suneo mocked him about how weird he was acting, and he got kicked by Suneo after attempting to become less malevolent towards his peers. This led him to lose control of his temper and start attacking his friends again.
Although he bullies the other children (mostly Nobita) and basically almost nothing scares him, including monsters, he is deathly terrified of his mother, who runs the local grocery store, tells him to deliver many goods, a fact Nobita and Doraemon sometimes use in their favor. He founded his own baseball team named after himself. Although Nobita is often blamed for the losses against the baseball team's rival, the "Tyranos", Gian always forces Nobita to play because they do not have enough players or simply because he doesn't care how terrible Nobita is at sports.
Gian is physically the strongest and probably the most athletically talented among the kids, and he's also the captain of the local baseball team — The Giants. Because of the poor skills of some members like Suneo or, more significantly, Nobita, the team often finds itself at the bottom of the league table. Defeats often lead to Gian's abuse of his teammates due to believing that winning is everything to him.
He often steals the comics of other children and even stealing Doraemon's gadgets from Nobita. Generally misusing them.
Gian is a gamer, but doesn't go in the competition between Nobita and Suneo. Gian's favorite games are Human Attack (Spoof of Mortal Kombat) N-ONE (Spoof of F-Zero) and Monkey Bong Jungle (Spoof of Donkey Kong Country).
He can also be quite cruel to animals, such as the time he tried to capture a little rabbit that Nobita, Doraemon and Shizuka saw and care about. And he and Suneo even once caught two tanukis with the net bazooka and planned on doing something cruel to them until Doraemon stopped Gian and Suneo with the Leopard Cat Glasses and Tail and hypnotized them into thinking they are dancing tanukis while freeing the real ones.
Gian's mother is often seen to be angry at him. Whenever she catches Gian shirking off his responsibilities of watching over the store and/or bullying innocent children, including Nobita, she would severely and physically punish Gian for his wrongdoings and misdemeanors. His mother is basically the only person that Gian is genuinely terrified of. Even hearing her voice would be enough to scare him and make him run away in cowardice.
Apart from his father and mother (whom he fears the most), Gian also has a younger sister called Jaiko. He is extremely protective of Jaiko, sometimes to her annoyance. Jaiko has an interest in writing comic books, so Gian helps her using Doraemon's gadgets, which frustrates her sometimes. Also, no matter what Nobita says about Jaiko like how he either likes or dislikes her, Gian would beat up Nobita anyways. Sometimes, however, she is grateful for the help that Gian lends from Doraemon.

— Suneo to Gian after Gian asked if he could see his homework in Nobita's Dinosaur
Gian and Suneo are shown to be really good friends (or possibly being best friends), but occasionally Gian will beat him up and Suneo sometimes complains that he dislikes Gian. In one episode Suneo commented that Gian thinks that Suneo and Nobita are objects to hit, not friends. That remark left Doraemon laughing but Nobita seemed to agree to that. But Gian is often seen with Suneo and they are actually very good friends together. Sometimes Gian comes to Suneo's house to study but ends up eating all his food. Suneo acts like a sidekick for Gian and a messenger for him. Although at some times, whenever Suneo gets his hands on Doraemon's gadgets, he would simply turn against Gian, and get back at him.
Doraemon and Gian's relationship is good as he has helped Gian in numerous episodes. Doraemon has felt sympathy and compassion for him as seen in some movies and episodes. However, Doraemon sometimes gets angry at Gian when he bullies others to a great extent. Sometimes, Doraemon would become terrified of Gian whenever he is about to beat him or Nobita up.

— Gian's true feelings about Nobita in Truthful Robot
While typically a sadistic bully, especially to Nobita, their relationship is good as sometimes they gang up on Suneo, and (though slightly forceful) Nobita tries to help Gian if possible. Often times he gets beaten up by Gian.
Gian often enjoys beating up and/or insulting Nobita, he even said: "If I don't bully Nobita a day, I can't eat and sleep any more." Although what he said could be an excuse for wanting to beat up Nobita for no reason at all or simply because he loves him too much that he takes pure joy out of making Nobita's life as miserable as possible. In fact, he'd stop at nothing until Nobita is violently wounded by him believing that Nobita must be punished for every stupid thing he does to him, including mocking him, being blunt and ruining his good day accidentally or purposely, losing the game due to his extremely atrocious skills, and for no reason at all. Sometimes whenever he gets his hands on Doraemon's gadgets, Gian would use it to get back at Nobita as well as enslaving him throughout the rest of the day believing it is the only way to teach Nobita a lesson or simply because he loves to be very close to him and torture him to no end. He doesn't even care at all if Nobita has different plans of his own, such as studying or spending the day with Shizuka. In fact, Gian is incapable of ignoring Nobita in every way possible or letting him go over a simple request by Nobita. Gian appears to be extremely dependent on Nobita and constantly forces him to do whatever needs to be done or whatever he wants and gives him impossible tasks. Just seeing him would be enough to easily catch his attention. However, in the episode Truthful Robot, both Nobita's robot and Gian's robot would rather be friends than enemies. Gian is usually the first one to support Nobita's decisions in the movies. They are also shown to be very close to each other, in the movie Nobita's South Sea Adventure, when Nobita falls into the sea, Gian holds his hand and tells him not to let go also in some other episodes he helps Nobita, as in one episode, Nobita gets sick, and Gian helps him off the ground. It is also shown in The Day Doraemon is Reborn when Gian rescued Nobita from plummeting to his death. He even cares for Nobita enough to save Doraemon when the earless blue robot cat got infected with a nearly-fatal virus.
Shizuka and Gian are friends, but Shizuka gets worried when Gian invites her to taste his food and his music concerts along with her other friends. Shizuka also doesn't like it when Gian bullies Nobita, but their relationship is good otherwise. Gian also listens to Shizuka to not bully people, but sometimes he doesn't listen. In one episode, he realized that Shizuka had used a gadget from Doraemon to try to make him stop bullying, even going as far to hit her, but she used the gadget to fling him up into a tree. Their relationship isn't too bad otherwise.
Muku is the only pet that Gian has and does not treat him well. Generally, Gian rarely walks and feeds him, while his younger sister Jaiko does the work of taking care of him. However, Gian has shown love to Muku many times, even though he considers him stupid and skittish.
