One example is 'Twilight' series. The character Edward Cullen is quite 'hot' in the eyes of many readers. He's a vampire with a brooding and mysterious charm.
The 'A Court of Thorns and Roses' series. Rhysand is a very hot character. He's powerful, mysterious and has a deep sense of loyalty towards the protagonist. His good looks and his ability to be both a fierce warrior and a loving partner make him stand out.
A character's passion can make them 'hot'. Heathcliff from 'Wuthering Heights' has an intense passion for Catherine that is both tragic and alluring. Their ability to love deeply and unreservedly can be a very attractive trait. Also, intelligence can be a factor. A character who is smart and quick - witted, like Sherlock Holmes (although not strictly a 'hot' character in the traditional sense but still appealing), can be seen as an attractive quality. And the way a character treats others, with respect and care like Four from 'Divergent' towards Tris, is also something that can contribute to their 'hotness'.
One of the hot fictional books is 'Harry Potter' series. It has captured the hearts of millions around the world with its magical world of Hogwarts, witches, wizards, and the epic battle between good and evil. Another is 'The Hunger Games' which presents a dystopian future where teens fight for survival in a televised battle.
For some, it's their physical beauty. For example, like Fleur Delacour in the 'Harry Potter' series, she is described as having a kind of other - worldly beauty. But it's not just about looks. It's also about their personalities. Characters like Eowyn from 'The Lord of the Rings' are hot because of their courage. She rides into battle against the Witch - king when no one else would. Their determination, like that of Tris Prior in 'Divergent', also adds to their allure as they face difficult challenges and overcome them.
One great book with badass fictional characters is 'The Lord of the Rings' by J.R.R. Tolkien. Characters like Aragorn are badass. He's a skilled warrior, a natural leader, and has the courage to face the dark forces of Sauron. Another is 'Harry Potter' series by J.K. Rowling. Harry himself is a badass as he battles the powerful and evil Voldemort throughout his life at Hogwarts and beyond, not to mention his friends Hermione and Ron who are also very brave. Then there's 'The Hunger Games' by Suzanne Collins. Katniss Everdeen is extremely badass. She volunteers for the Hunger Games to save her sister and shows remarkable survival skills and defiance against the Capitol.
Frodo Baggins from 'The Lord of the Rings' is an amazing fictional character. He undertakes an almost impossible quest to destroy the One Ring. His small - stature hobbit shows great courage and tenacity in the face of overwhelming evil. Atticus Finch from 'To Kill a Mockingbird' is also a great character. He is a moral compass in a racially divided town, standing up for justice and teaching his children important values. Also, Scarlett O'Hara from 'Gone with the Wind' is a complex character. She is vain and selfish at times, but also strong and resourceful as she tries to survive during the Civil War and Reconstruction era.
Another iconic character is Harry Potter from J.K. Rowling's series. Harry is a young wizard who discovers his magical abilities and battles the dark forces. The books are not only about magic but also about friendship, courage, and growing up. The series has a huge global following and has made a significant impact on popular culture.
Definitely check out 'Eragon'. It's an epic fantasy about a boy and his dragon. It has adventure, magic, and a great story arc. 'The Mortal Instruments' series is also popular among young adults. It combines the modern world with the world of demons, angels, and shadowhunters.
