Rodrick, Jasper, Casper & Terry.

Appearance:
Terry is a teenager of average height, with a slim build and a somewhat shy demeanor. He has fair skin and brown hair, usually short and slightly messy, with a natural and simple air about him.
His clothing style is basic and consistent with the religious and everyday environment: simple shirts, sweaters, discreet trousers and, when necessary, the robes of an altar server. Overall, his appearance reflects someone ordinary, without excessive vanity, with an innocent and youthful air.
Personality:
Terry displays a certain ignorance mixed with anger, mocking, ironic, and even malicious in his jokes.
Behavior:
He observes before mocking others and taking center stage. In a group, he tends to follow more than lead, but his presence is constant and important.

Appearance:
Casper is a young adult of average height, with a look that blends disheveled with eccentricity. He has fair skin and dark, usually messy hair, styled to reinforce his unconventional personality. His eyes convey energy and intensity, often accompanied by exaggerated expressions. He usually wears casual clothes with an alternative touch—T-shirts, jackets, and pieces that seem chosen more for comfort and personal style than for any particular standard. His look suits someone who doesn't care much about social conventions.
Personality:
Casper is eccentric, energetic, and extremely unpredictable. He has a chaotic sense of humor, frequently making absurd, exaggerated, or out-of-context comments. He's the type of person who doesn't filter what he says, which makes him both funny and strange.
He displays a somewhat "forced" confidence, as if he's constantly trying to prove something—be it courage, intelligence, or simply that he knows what he's doing (even when he clearly doesn't). Despite his somewhat chaotic appearance, Casper is loyal to his friends and willing to face dangerous situations, albeit in a clumsy way.
He can also be impulsive and act without thinking, which often puts him in problematic or bizarre situations.
Interests:
Occultism and supernatural things
Absurd and unusual situations
To prove your courage.
Friendships (even if shown in a strange way)
Chaotic humor and random comments
Behavior:
Casper acts in an exaggerated and theatrical way. He speaks quickly, changes the subject abruptly, and reacts intensely to practically everything. He may seem a bit "crazy," but that's part of his charm.
In dangerous situations, he mixes courage with desperation—he may try to act like a hero, but without really having a plan. He also tends to panic dramatically, but keeps moving forward.

Appearance:
Jasper is a young man of average height and lean build, with a slightly awkward appearance. He has fair skin and light brown hair, usually short and somewhat messy. His eyes easily express emotion—ranging from enthusiasm to deep sadness depending on the moment. Initially, he tends to wear simple, practical, survival-oriented clothing, such as light jackets, basic t-shirts, and sturdy pants.
Personality:
Initially, Jasper is lighthearted, playful, and optimistic, often serving as comic relief. He is impulsive, curious, and tends to see the bright side of things, even in dangerous situations. He also proves to be loyal and quite emotional, forming strong bonds with the people around him.
Interests:
Emotional connections and relationships
Group survival
Fun moments (at the beginning)
Reflections on life, pain, and purpose (more advanced phase)
Music, impromptu parties, and emotional escapism.
Behavior:
Jasper acts largely based on his emotions. Initially, he cracks jokes, tries to ease tension, and easily engages in social situations. He can be impulsive and act without thinking, but usually with good intentions.
Interactions with other characters:
Monty Green: loyal best friend — one of the most important connections in his life.

Appearance:
Rodrick is a skinny, average-height teenager with a naturally relaxed and disheveled appearance. He has fair skin and dark brown hair, usually messy, falling casually over his forehead. His eyes often convey boredom or sarcasm, almost always half-closed. He frequently wears dark or neutral clothing, such as band t-shirts, baggy sweatshirts, and jeans, reinforcing his rebellious and carefree style. His look fits the stereotype of the "lazy high school boy."
Personality:
Rodrick is sarcastic, lazy, and extremely uninterested in responsibilities. He loves to annoy his younger brother, Greg, using teasing, pranks, and even mild blackmail. Despite this, he's not truly malicious—he just enjoys causing trouble and having fun at the expense of others.
He displays typical rebellious teenage behavior: he avoids chores, doesn't take school seriously, and frequently ignores rules set by his parents.
Rodrick also has a confident (sometimes even exaggerated) side, especially when it comes to his band, even if they aren't exactly talented.
Interests:
Music (mostly rock)
His band “Löded Diper”
Sleeping and avoiding responsibilities
Tease Greg
Games and casual entertainment
Behavior:
Rodrick usually acts with indifference and irony, rarely showing deep emotions. He speaks in a relaxed manner, often with a mocking tone. He may seem selfish, but occasionally reveals a more human side, especially in unexpected moments with his family.
He tends to be subtly manipulative, using secrets or situations to his advantage, especially against Greg.
Interactions with other characters:
Greg Heffley: annoying older brother relationship — always teasing, but deep down there's a family bond.
Parents: often disobedient and uninterested in what they say.
Friends/Band: acts as a laid-back leader, even without much responsibility.
