• Jiang Xiaoyu (江小魚; 江小鱼; Jiāng Xiǎoyú; Gong1 Siu2-jyu4), better known as Xiaoyu'er (小魚兒; 小鱼儿; Xiǎoyú'ér; Siu2-jyu4-ji4) aka Little Fish or Small Fry, is Jiang Feng and Hua Yuenu's son. He was raised by the Five of the Ten Great Villains and trained to become a great villain. Though his body is covered in scars due to his brutal upbringing, Xiaoyu'er possesses considerable charm and rugged good looks which allow him to leave a lasting impression on every woman he meets. Although a respectable fighter, Xiaoyu'er prefers to rely on his intelligence, cunning, and a variety of skills such as thievery and deception that were imparted to him by his villainous tutors to overcome challenges. However, when he encounters the lethally effective Hua Wuque, Xiaoyu'er realises that tricks alone cannot be relied on to keep him alive, and devotes himself to improving his fighting ability, ultimately finding a martial arts manual, learning the advanced styles set out in it, and growing into a formidable martial artist in his own right. Although his tough upbringing causes him to adopt a callous, hedonistic persona in public, Xiaoyu'er actually has a strong moral compass and is naturally kind and protective of others.
• Hua Wuque (花無缺; 花无缺; Huā Wúquē; Faa1 Mou4-kyut3) is Xiaoyu'er's twin brother. He is the heir to Yihua Palace and its only male resident. He bears a striking resemblance to his father, and has a more androgynous beauty than his brother.

However, he has a tendency to suppress his emotions and has a naive outlook towards life.
• Tie Xinlan (鐵心蘭; 铁心兰; Tiě Xīnlán; Tit3 Sam1-laan4) is the daughter of Tie Zhan, one of the Ten Great Villains.

She later falls in love with Hua Wuque, who has strong feelings for her.

• Su Ying (蘇櫻; 苏樱; Sū Yīng; Sou1 Jing1) is Wei Wuya's foster daughter. She is spoiled, arrogant, scheming and anti-social. She is well-versed in medicine and extremely cunning but has no significant martial arts skills. Her intelligence enables her to manipulate many martial artists throughout the novel. Her beautiful appearance and indifferent personality are similar to those of Yaoyue and Lianxing – which was why Wei Wuya adopted her. When she meets Xiaoyu'er, she falls in love with him and decides to follow him until she wins his heart. She is more intelligent than him and knows how to adapt her behaviour according to his mood – thereby making her the only person who can effectively control him.
• Yan Nantian (燕南天; Yàn Nántiān; Jin3 Naam4-tin1), nicknamed "Best Divine Swordsman Under Heaven" (天下第一神劍), is the most powerful martial artist in the novel. He is Jiang Feng's sworn brother.

He is said to be so powerful that he can shave a man bald in a single move without the person noticing. He is massive in stature and dresses like a pauper. He is ambushed by the Ten Great Villains and enters a coma. He is revived by the physician Wan Chunliu, who kept him alive under the pretext of using his comatose body to test new drugs. He awakens only to find that he has lost most of his original abilities, and trains for long months to regain them, eventually even surpassing his previous level of power. He serves as Xiaoyu'er's role model and trains him in martial arts.

• Taohua (桃花; Táohuā; Tou4-faa1) is a nomadic girl living on the plains. She is the first maiden Xiaoyu'er meets on his adventures. She plays a hospitable host to him.
• Zhang Jing (張菁; 张菁; Zhāng Jīng; Zoeng1 Zing1) is nicknamed "Little Fey" (小仙子). Although beautiful in appearance, she is extremely brutal. She has a fiery temper and hates evil to the core. Although not a very powerful martial artist, her moves are very fast, making her a formidable challenge even to more powerful opponents. Once, to comfort her mother, she decides to find the treasure left behind by her mother's ex-lover, Yan Nantian. She follows Tie Xinlan, who finds the treasure and meets Xiaoyu'er along the way, who gives her her first kiss. Ultimately marries Gu Renyu.
• Murong Jiu (慕容九; Mùróng Jǐu; Mou6-jung4 Gau2) is a member of the Murong family. She seems very cold towards people because she practises the 'Rock Altering Divine Skill' (化石神功), a form of martial arts that cultivates inner strength by suppressing the emotions.

• Hai Hongzhu (海紅珠; 海红珠; Hǎi Hóngzhū; Hoi2 Hung4-zyu1) is the only child of Hai Laodie, the leader of a wandering performance troupe.

She appreciates Xiaoyu'er's talents and recruits him to be in charge of the medicine shop. She helps Xiaoyu'er once in solving a mystery case. Xiaoyu'er influences her to dress like a woman.

• Yaoyue (邀月; Yāoyuè; Jiu1-jyut6) is the first mistress of Yihua Palace. Although she possesses beauty, charisma and skill, she is described by Jiang Feng as "not a living person or human being, but fire, a block, ice or a sword instead". Jiang Feng rejects her and elopes with one of Yihua Palace's slave girls, Hua Yuenu. Yaoyue is angered and she pursues and hunts down the couple. After Jiang Feng and Hua Yuenu die, Yaoyue intends to kill their twin boys but Lianxing stops her. The sisters choose one of the twins and raise him as their son and groom him to be the heir to Yihua Palace. According to Lianxing, before Yaoyue and Yan Nantian mastered all their respective skills, Yaoyue was slightly better than Yan, making her the most powerful martial artist at the beginning of the novel.
• Lianxing (憐星; 怜星; Liánxīng; Lin4-sing1) is the second mistress of Yihua Palace and Yaoyue's younger sister. She is described to be a sweet and pretty woman whose beauty surpasses that of a flower blooming in spring. According to Xiaoyue'er, in comparison to Yaoyue, Lianxing is warmer in character than her sister. This is confirmed by Tie Pinggu, because Lianxing, like Yaoyue, had also fallen in love with Jiang Feng, but was afraid to express her feelings for fear of her sister. After Jiang Feng and Hua Yuenu die, Lianxing saves the twins by suggesting to make them kill each other when they are grown up instead of killing them now. Throughout the novel, it is hinted that Lianxing, unlike Yaoyue, does not take the revenge plot seriously. Hua Wuque sees Lianxing as a mother-figure and treats her with love and respect. Compared with Yaoyue and Yan Nantian, Lianxing is slightly weaker in martial arts than her sister, but equal to Yan.

• Gu Renyu (顧人玉; 顾人玉; Gù Rényù; Gu3 Jan4-juk6) is nicknamed "Jade Faced Divine Fist" (玉面神拳). He is honest, simple and easily embarrassed. He practises his family's martial art 'Gu Family Divine Fist' (顧家神拳), which blends in well when combined with Zhang Jing's palm skills. He is initially ordered by his mother to woo Murong Jiu, but falls in love with Zhang Jing instead and eventually marries her.
• Black Spider (黑蜘蛛; Hēizhīzhū; Hak1-zi1-zyu1) is a martial artist who dresses in a tight black suit and has a mechanical device strapped to his wrist capable of shooting spider web fluid at enemies. He is an expert in qinggong and is capable of scaling walls with his 'Flying Silver Threads' (銀絲飛渡) skill. He has a strong personal ego and likes to play the role of an older sibling to his friends. He is in love with Murong Jiu but is afraid of confessing to her so he always watches her from a distance. When Murong Jiu ventures into the jianghu, he follows her closely and protects her with his life. They are married eventually.

• Jiang Biehe (江別鶴; 江别鹤; Jiāng Biéhè; Gong1 Bit6-hok6) is Xiaoyu'er's primary nemesis. He was originally Jiang Feng's servant and was previously known as Jiang Qin (江琴; Jiāng Qín; Gong1 Kam4). He betrayed his master for monetary rewards and became an influential nobleman and martial artist. He is brutal and ruthless by nature, but also intelligent and adept at deception. He is hailed as a "Hero of Jiangnan" for pretending to perform heroic and kind acts, while secretly conducting wicked deeds such as extortion and assassinations. When Xiaoyu'er attempts to expose his hypocrisy in public, he attacks Xiaoyu'er verbally and accuses him of committing the very atrocities he is responsible for. However, this backfires when he is tricked into revealing his involvement in those atrocities. He is eventually captured and crippled by Yan Nantian, who sends him to Xiaoyu'er for punishment. Xiaoyu'er spares his life and allows him to leave.
• Jiang Yulang (江玉郎; Jiāng Yùláng; Gong1 Juk6-long4) is Jiang Biehe's son, who was named after Jiang Feng's nickname. He is trained by his father in martial arts and groomed to support his father in his quest to dominate the jianghu. He has a pale complexion and appears feminine. He is an expert in charming and seducing women, and his many "trophies" include Tie Pinggu.
• The Ten Great Villains (十大惡人; 十大恶人; Shí Dà È Rén; Sap6 Daai6 Ngok3 Jan4) are ten notorious criminals in the jianghu. In spite of their collective nickname, they are not an official group per se because they often operate independently. Furthermore, their fame is due more to their various eccentricities and quirks rather than actual villainy. Most of the ten are not even evil at all. The five who raised Xiaoyu'er are Du Sha, Haha'er, Tu Jiao Jiao, Li Dazhui and Yin Jiuyou. They develop an emotional attachment to the boy and treat him with a degree of affection. As such, Xiaoyu'er respects them as his surrogate parents and manages to convince Yan Nantian to spare them. By the end of the novel, all the original ten are dead except for San Guang and Tie Zhan.
• The Twelve Zodiac (十二星相; Shí Èr Xīngxiàng; Sap6 Ji6 Sing1-soeng3) are a group of bandits named according to the twelve Chinese zodiac signs. They are led by the "Rat" Wei Wuya, a paraplegic yet incredibly dangerous martial artist. Wei Wuya previously fell in love with the sisters of Yihua Palace and challenged them to marry him but lost.

In 1997, Hong Kong cartoonist Ho Chi-man drew a manhua series for the novel.

Wong Yuk-long's comic, Force of Buddha's Palm (如來神掌) has a long story arc which reproduces much of Gu Long's novels. This story arc was included in an English translation published in the United States by Jademan Comics from 1989 to 1993.

Ho Che Wen created three comic series based on this story under the title The Impeccable Twins. The first series follow the novel but the second and the third series expand on events after the end of the novel.
