The signs as Avatar the last Airbender characters
Aries:Iroh; passionate, a leader, wise, dynamic and adaptable, very warm person, charming, when they get mad they get mad, creative, and impulsive. (Iroh is the wisest character in the show but also bought out an entire market and ate a plant because he thought it might be tea. He was also one of the strongest characters in the whole show)
Taurus:Suki; very intelligent and capable, hard working and dedicated to their craft and cause, well defined style, stubborn and, trustworthy. ( She’s very smart and capable like look at the prison break episode she said i got this bitch hold my beer)
Gemini:Ty Lee; outgoing, friendly, somewhat impulsive and indecisive, easy going, loyal to a fault, big personality, adaptable, and two sided. (Ty Lee on the outside was super perky and friendly, but she could also was not afraid to speak her mind and be blunt/bold. Also she took down Azula!!)
Cancer:Yue; loyal and protective of her people, willing to make sacrifices to help those she loves, compassionate and loving, very intuitive. (She has a very strong sense of duty without being told what she had to do and was traditionally soft, but also very brave.)
Leo:Zuko; Prideful, emotional, kind hearted, determined, head strong, spiteful, and brave. (His entire story arc is trying to reclaim his honor honestly)
Virgo:King Bumi; cheerful, expressive, creative and clever, strong, reliable, observent, smart, fussy, and skeptical. (bumi honestly kinda a wildcard but it also feels like everything he does is intentional. He’s playing a bigger game than he lets on /kinda like a better dombledore don’t at me/)
Libra:Aang; diplomatic, clever, idealistic, tries to see the good in everything, social, non-confrontational, provides balance, self-pitying, and fun loving. (Aang just wanted to vibe and was a child at heart through and through, but that never stopped him from doing what he had to do, and doing things the way he wanted them to be done.)
Scorpio:Azula; Determined, Disciplined, perfectionist, cunning, love to hate her, intelligent, assertive, and competitive. (Azula day one said I’m the best there is and that’s on that. She’s such a badass and a force to be reckoned with.) 
Sagittarius:Mai; Blunt, impatient, caring (i know she says she doesn’t care ALOT but she was willing to fight Azula for Zuko), private, brave, loyal to a point, irritable, and forgiving. i know she’s not a traditional Sag but looking closer she’s kinda a more introverted sag and and absolute baddie. Also very expressionistic in not wanting to be expressive //emo//)
Capricorn:Sokka; sarcastic, highly ambitious, realist, strategist and brains, reliable, and, open hearted. (Sokka has major dad vibes he’s a big goof, but he’s very smart and capable.)
Aquarius:Toph; Rebellious, original, condescending, intelligent, independent, somewhat unpredictable, will call people out, hates authority, and stubborn. (Toph could not have given a single fuck and danced to the beat of her own drum. She ran away and was one of the most powerful benders of all time.)
Pisces:Katara; empathic and emotional, generous, motherly, overly trusting, naïve, and, inspiring. (She’s emotional but also not afraid to fight a mother f*cker. ya she’s the mom of the group but that has never stopped her from just challenging a master to a fight day one.)
