Superman

Jor-El is Kal-El's father. A prominent Kryptonian scientist, he realized the planet was doomed and sent his son to Earth to save him. He often appears as a hologram, recording, or AI, imparting Kryptonian wisdom and knowledge to his son.
Lara Lor-Van is Kal-El's mother. She supported Jor-El and was also involved in the decision to save her son. In most stories, she dies along with Krypton.
Zor-El and Alura In-Ze are Kal-El's aunt and uncle (Jor-El's brother and wife). They sent their daughter, Kara, into space, who became known as Supergirl.
Jonathan Kent – ​​his adoptive father, a farmer from Smallville who taught Clark responsibility and the importance of using power for good. His teachings became Superman's moral foundation.
Martha Kent is Clark's adoptive mother. According to many versions, it was she who designed Clark's costume and the "S" emblem. Martha instilled in him empathy and the ability to see the good in people.
Lois Lane is Clark Kent's lover, and in many versions, his wife. She is a journalist who values ​​him not only as a hero but also as a human being. Their relationship is an important part of Superman's character: from Lois, he learns to be more relatable to ordinary people.
Jon Kent is the son of Superman and Lois Lane in modern comics (such as the DC Rebirth series). He is a young superhero who continues his father's legacy.
Kara Zor-El (Supergirl) is Kal-El's cousin, also from Krypton. In some stories, she grew up alongside him or came later, but she always remains an important part of his "family"—both in blood and in spirit.
Krypto is a superdog from Krypton. He's not related by blood, but in some stories he's considered a full-fledged member of the family. He also has superpowers and often helps Kal-El.

Superman draws his powers from Earth's yellow sun, meaning that if Superman were deprived of the sun, he would become powerless. His powers include:

Superpower: able to lift enormous weights and move planets (the scale varies in different versions).
Flight: can fly both in the atmosphere and in space.
Invulnerability: Takes almost no damage, but is vulnerable to kryptonite, magic, and some super-strong enemies.
Super speed and super reflexes: moves faster than sound, able to react to the smallest threats.
Special types of vision: thermal vision (emits rays from the eyes), x-ray vision (sees through objects except lead), telescopic and microscopic vision.
Super hearing: hears sounds over great distances.
Fast Regeneration: Regenerates quickly when supplied with solar energy.

The classic look: a blue suit, red shorts over tights (often removed in newer versions), a red cape, and an "S" emblem within a shield. The colors are symbolic: blue and red refer to the US flag, and yellow represents light and the energy of the sun.

Real name on Krypton: Kal-El.
Earth name: Clark Kent.
Origin: He hails from the planet Krypton, which was destroyed before he came of age. As an infant, he was sent to Earth, where he was adopted by Jonathan and Martha Kent of Smallville.

Main allies and close friends: Lois Lane (journalist, often lover), Batman (complicated but respectful relationship), Justice League.

Main character traits

Altruism and a sense of duty. Superman doesn't use power for profit: he helps because he believes it's right. Hence his famous "truth, justice, and a better world" philosophy. For him, power is responsibility.
Optimism and faith in people. He believes that most people are capable of goodness and tries to give everyone a second chance. This distinguishes him from more cynical heroes like Batman.
Modesty and inconspicuousness in everyday life. As Clark Kent, he deliberately appears "ordinary": a little awkward, shy, and not one to push his luck. This isn't just a disguise, but also a reflection of his values—not to stand out, but to quietly do his job.
Empathy and compassion. He acutely feels the pain of others and strives not just to "fix" a problem, but to understand it. Hence his reluctance to kill or maim even villains: he seeks ways to neutralize, not destroy.
Integrity. He has clear moral boundaries that he doesn't cross: he doesn't kill, he doesn't take revenge, he doesn't use force to intimidate. This sometimes makes him vulnerable, but for the writers, it's a fundamental trait.
Dual identity. Clark Kent and Superman aren't just masks, but two ways to be useful: as a journalist, he seeks the truth and tells people's stories; as a superhero, he directly protects them.
Not only is Lex Luthor obsessed with Superman, but Superman is mutually obsessed with Lex.
