Shizuka, usually called Shizu-chan (��ゃん) or Shizuka-chan (�香�ゃん), is the smart, kind, and pretty neighborhood girl who is the object of Nobita's affections. She takes baths several times a day. Nobita often disrupts her in the bath due to some misuse of Doraemon's gadgets, resulting in Nobita's head getting dunked. She is also known for taking piano lessons unwillingly, which is sometimes used as an excuse for declining to hang out with Nobita. Her true passions are sweet potatoes, which she'd rather keep to herself out of the knowledge of others, and the violin, in which her playing is as atrocious as Gian's singing. Due to Doraemon's intervention, Shizuka will become Nobita's wife in the future timeline, and the mother of his son. (Source: Wikipedia)
Takeshi, usually known by the nickname "Gian" (ジャイアン, Jaian) from English word "giant", is the big, strong, and quick-tempered local bully. He is known for his confidence in his terrible singing voice, though he considers himself a great singer. 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. He also frequently steals other children's toys and books under the pretext of "borrowing" them, unless the toy is damaged. This is how most fans considered Gian to be the antagonist of this show. 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 realize 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 his friends at school or at the streets mock him to see how weird Gian was acting and get kicked by Suneo after learning his attempt to become gentle to 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), he is terrified of his mother, who runs the local grocery store, 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 and Suneo still force Nobita to play because they do not have enough players. Gian also has a younger sister named Jaiko, whom he adores. (Source: Wikipedia)
Nobita is one of the main characters of the Doraemon series. A fourth grader in Tokyo and only child, he is the quintessential flawed protagonist. He is lazy, bad in sports, bad in school, plain as a gray rock, and to top it off, all too unlucky in his (mis)adventures with Doraemon. However, his struggles to overcome his flaws are what drive the storyline.
Belca Noctircus is the third prince in the royal Noctirous family and is the main protagonist. He is not of pure royal blood like his two older brothers, Hector and Orcelito and younger sister, Musca. Since his father had an affair with a commoner woman, Belca is often looked down with scorn and pity. He is often insulted and made fun of and is disliked by his younger sister Musca. Belca hates the castle life and wishes to leave but he admires his elder brother Hector and hopes that if one day the kingdom is ruled by a "weird guy" (Hector) and a "serious guy" (Orcelito) he might just want to stay. However, before Hector's coronation ceremony, he is apparently killed by his chronic disease. A while later, Belca discovers the conspiracy behind his oldest brother's death and is now being pursued by the elders. He now travels with Eco and often has to cross-dress as a woman called Mariebelle to avoid being captured. Belca is also often confused and surprised by a lot of things such as warm food outside of the castle and how much his ring is worth. He is skilled with the sword and at the start of the story he hates the Amontel since he believes that they indirectly caused Hector's death. As the story goes we see that he is a kind and naive young man who loves his friends and siblings very much, and that he will never let them suffer for him. (Source: Wikipedia)
He was the crown prince and known for his tolerance but he was killed by the council of elders because he wanted the Amontel to be recognized as humans.
