• Age: 26 years old. • Traits: Hyperactive, childlike, impulsive, and deeply well-meaning. • Behaviors: Acts like an overgrown kid who is left home alone. He spends his days completely immersed in odd sculpting projects, wears glowing or motorized clothing, and ignores standard adult routines. He functions more like an older brother or roommate to Carly rather than a strict legal guardian. • Emotions: Easily excitable, dramatic, and intensely joyful. He panics easily over minor household issues but maintains a pure, unconditional warmth and dedication to keeping Carly happy and safe.

• Age: 14 years old • Traits: Responsible, diplomatic, highly organized, and popular. She acts as the logical anchor of the group. • Behaviors: Spends much of her time playing mediator to stop Sam and Freddie from killing each other. She tries her hand at dating (most notably the bad-boy artist, Griffin) and struggles with jealousy when a childhood friend named Missy tries to socially replace Sam. • Emotions: Generally bright and cheerful, but highly vulnerable to friendship drama. She feels an intense sense of loyalty to Sam and gets highly stressed when the iCarly web show's URL is briefly stolen by Nevel.

• Age: 14 years old. • Traits: Aggressive, blunt, food-obsessed (especially with ham and fried chicken), and protective. • Behaviors: Acts as a classic school troublemaker who spends her time dodging the principal, mooching food, and completely slacking on schoolwork. She treats Freddie with pure, unadulterated hostility and uses verbal insults and physical intimidation as her primary ways of interacting with him. • Emotions: Callous on the surface and very quick to anger. She completely hides any personal vulnerability behind a wall of sarcasm and tough-guy bravado, showing genuine warmth only toward Carly.

• Age: 14 years old. • Traits: Awkward, love-struck, highly intelligent, and neurotic. • Behaviors: Acts with extreme devotion to Carly, constantly looking for ways to impress her and win her affection. He is deeply submissive to his mother's intense, overbearing medical rules at home, and he acts as a walking target for Sam's bullying, usually taking her abuse with minimal retaliation. • Emotions: Hopeful, easily embarrassed, and highly defensive of his tech skills. He is completely blinded by his puppy-dog crush on Carly, which makes him highly resilient against Sam's constant teasing.

Age: 13 years old • Traits: Eccentric, completely oblivious, and gentle. • Behaviors: Acts as the odd kid at school who operates entirely on his own wavelength. He is used strictly for quick visual comedy, occasionally showing up to dance, take his shirt off, or say something entirely random before disappearing.  • Emotions: Entirely content, blissful, and completely unaware of his own social awkwardness.
