In "Gulliver's Travels," the primary distinction between the Lilliputians and the Brobdingnagians lies in their character and size. The Lilliputians, despite being small, are cruel and exploitative, using Gulliver for their gain. Conversely, the Brobdingnagians, despite being giants, are good-willed, virtuous, and respectful, treating Gulliver with care and dignity. Furthermore, the Lilliputians' society is characterized by petty disputes and conflicts, while the Brobdingnagians seek peace and harmony.

Gulliver is named "Quinbus Flestrin" by the Lilliputians because of his enormous size compared to their tiny stature. The name translates to "the Man-Mountain" or "the Great Man Mountain," highlighting how perspective can drastically alter the perception of size and significance. This nickname underscores a major theme in Gulliver's Travels: the importance of perspective.

In Gulliver's Travels, Gulliver has two enemies in Lilliput. The first is Flimnap, the lord high treasurer, and the second is Skyresh Bolgolam, the high-admiral. The two work together to persuade the emperor that Gulliver's behavior is treasonous and that he should be killed.

The King of Brobdingnag is depicted as open-minded and hospitable, showing interest in Gulliver's stories about English politics. His critical view of English society highlights his higher moral standards and sense of humor. He rejects the use of gunpowder, valuing his people's welfare over power, portraying him as a benevolent ruler. Swift uses the King to critique English politics, presenting him as a wise judge of Gulliver's homeland.

The Blefuscu emperor in "Gulliver's Travels" is characterized by generosity, fairness, and virtue. He welcomes Gulliver warmly and aids in his departure by offering ships and materials to repair his boat, unlike the Lilliputian emperor. The Blefuscu ruler also provides Gulliver with gifts like gold and provisions for his journey. He is forgiving of Gulliver's past actions against Blefuscu and does not exploit him, showcasing a more virtuous nature than his Lilliputian counterpart.

The King of Brobdingnag views the past hundred years of English history as a series of conspiracies, rebellions, and violent acts driven by greed, ambition, and malice. He is appalled by the English people's behavior, describing them as bloodthirsty, hypocritical, and malicious. The King criticizes England's mercenary army and frequent wars, concluding that the British are a "pernicious race of little odious vermin." His perspective highlights the violence and moral corruption in English history.

The Emperor of Lilliput's court is characterized by its absurdity and trivial qualifications for court positions, such as rope-dancing, reflecting a superficial and warlike nature. The Emperor is aggressive, focusing on petty conflicts. In contrast, the King of Brobdingnag's court is peace-loving and generous. The King is horrified by Gulliver's accounts of England's wars and weaponry, viewing them as barbaric. This highlights the satirical comparison between England and the two fictional courts.

In Gulliver's Travels, Skyresh Bolgolam is a High Admiral of Lilliput and Gulliver's greatest enemy at the Lilliputian court.

Struldbrugs are immortals in Gulliver's Travels marked by a spot on their forehead, indicating their eternal life. Initially, they live like ordinary people, but after thirty, they become increasingly miserable and isolated. By eighty, they are legally dead, losing all possessions to heirs. At ninety, they deteriorate physically and become linguistically isolated over centuries. This immortality leads to a wretched existence, making them despised and considered ominous by society.

The King of Lilliput is depicted as a comically absurd and pompous autocrat. Though he takes himself seriously, he is small-minded and vindictive, punishing minor offenses harshly. Despite his court's grandeur, he is a petty tyrant, eager to conquer Blefuscu without reason. Although he believes he holds power, he is easily influenced by his ministers. His demand for absolute loyalty leads him to plot against Gulliver when he refuses to attack Blefuscu.

Skyresh Bolgolam is an amusing character due to his baseless antagonism towards Gulliver, which leads him to undermine and attempt to impeach him despite Gulliver's contributions to Lilliput. His irrational hatred is intriguing and reflects human motivations. Alternatively, the Emperor is also interesting for his pragmatic yet cautious treatment of Gulliver. His reactions reflect those of a real politician, balancing Gulliver's potential usefulness and threat to his kingdom.

The Queen of Brobdingnag is portrayed as a kind but somewhat naive character who regards Gulliver as a pet. She is delighted by his wit and intelligence despite his small size and ensures he is well cared for. The queen is generous and affectionate but lacks deep understanding of Gulliver's fears and struggles. Her amusement with Gulliver reflects her simplistic view, highlighting her kindness rather than insightfulness in Jonathan Swift's satirical narrative.

Gulliver serves as both an everyman and a character with a distinctive personality. As an everyman, he represents the typical Englishman, blind to his own and his society's flaws, allowing Swift to satirize English politics and religion. However, Gulliver also reflects Swift's views in satirical passages and appears foolish in exaggerated scenarios, highlighting human greed and folly. Thus, Gulliver embodies both a universal human nature and distinct characteristics.

Gulliver, the third of five sons, pursued a medical career with his father's support. He apprenticed under Mr. James Bates and studied navigation and math, anticipating a future at sea. Despite attempts to establish a medical practice, failures led him to serve as a ship's doctor on voyages. His ventures were largely unsuccessful, with failed practices and voyages, until a shipwreck led him to Lilliput, where the main adventures of his story begin.

Gulliver's interactions with the Houyhnhnms challenge traditional human-animal relations by presenting intelligent horses and brutish Yahoos. Gulliver identifies more with the rational Houyhnhnms than with humans, leading him to view humanity as animalistic. This perspective questions the morality of human dominance over animals, suggesting that domestication could be akin to slavery. The Houyhnhnms' intelligence contrasts with human corruption, prompting Gulliver to reassess the nature of human superiority and animal potential.

Gulliver is depicted as curious, adventurous, and open-minded, traits that drive his voyages. He is also rational and observant, often analyzing the cultures he encounters. Despite his intelligence, he can be naïve and overly trusting, leading to his exploitation. His experiences gradually make him more cynical and misanthropic, reflecting his disillusionment with humanity.

At the beginning, Gulliver is distinguished from a Yahoo by his clothing and ability to communicate. The Houyhnhnms initially mistake him for a Yahoo, but his clothes and rational speech set him apart. When compared directly to a Yahoo, Gulliver is shocked by their similar human form, but the Houyhnhnms recognize his reasonableness and communication skills, which mark him as different and deserving of respect as a rational being.

The Emperor of Lilliput in Gulliver's Travels is a complex character. He is depicted as being both ambitious and somewhat tyrannical, with a desire for power and control. He is also portrayed as being somewhat petty and vain, focusing on trivial matters and expecting absolute loyalty from his subjects. Despite his flaws, he is an effective ruler who manages to maintain order in his kingdom.

The king of Brobdingnag is portrayed as a sympathetic character in "Gulliver's Travels," though not the most sympathetic. While he is reasonable, a good listener, and an excellent questioner, he is also judgmental, reflecting the rashness of English society that Swift satirizes. The Houyhnhnms are considered more sympathetic due to their rationality and the logical, harmonious society they create, which Gulliver admires.

Gulliver's life is marked by his attempts to establish a successful career amid financial struggles.

The Yahoos in "Gulliver's Travels" are depicted as brutish and uncivilized creatures, embodying humanity's basest instincts.

This comparison highlights the differences between Gulliver's perceived civility and the Yahoos' raw nature, ultimately critiquing human behavior and societal norms.

Gulliver's experiences with the Lilliputians and Blefuscudians reveal his character as fair-minded and gentle, though somewhat socially unaware. Despite his ability to overpower the Lilliputians, he chooses not to harm them, demonstrating his mild disposition. He also refuses to enslave the Blefuscudians, showing his commitment to justice. His actions, such as extinguishing a fire with urine, while offensive to some, highlight his practicality and kindness amidst the Lilliputians' trivial conflicts.

In "Gulliver's Travels," Gulliver fights in the conflict between Lilliput and Blefuscu, sparked by a disagreement over how to crack eggs.

He refuses to help Lilliput conquer Blefuscu fully, opposing the injustice, which results in backlash against him. Ultimately, Gulliver's intervention helps resolve the conflict with minimal harm.
