"What's your sign?" is a near-ubiquitous question in the Western world and it's not hard to see why. Besides being a handy organizing principle to guess someone's strongest character traits, it was also once regarded as actual science. It wasn't until the adoption of the scientific method at the end of the 19th century that astrology was demoted to a pseudoscience with no real bearing in empirical science.
These days, astrology has become a conversational icebreaker instead of a guiding principle for someone's life, but it's still a fun way to get to know someone... or even to design a fictional character. For even the staunchest of non-believers, astrology does have some basic utility in creative works and it's one tactic that creators can use when writing characters. Although many characters aren't given exact birthdays, it's still possible to group them into one sign or the other based on their strongest personality traits.
12 ARIES: Buttercup Is Passionate, Competitive, & Tough (Powerpuff Girls)
It should be no surprise that the toughest fighter of the Powerpuff Girls lineup qualifies as an Aries. Aries is the first sign in the zodiac and is known for being action-oriented, brash, and bad-tempered. Aries is also known for being excitable and confident, using their daring natures to bravely push forward even during the scariest moments. Buttercup's bravery, impatience, and argumentative nature easily align her with Aries' more notable traits.
11 TAURUS: Ed Is Steadfast, Deliberate, & Obstinate (Ed, Edd n Eddy)
Taureans are known for their indulgent and laid-back natures, making Ed from Ed, Edd n Eddy a suitable candidate for this zodiac sign. Ed is known for being patient and even-tempered until pushed too far, in which case he can exhibit a stubborn and explosive temper. He's also quite the foodie and indulges in all manner of junk food to the point of excess, traits he shares with the Taurus zodiac sign. His simple-minded and straightforward personality vibes very well with Taurus qualities.
10 GEMINI: Beast Boy Is Adaptable, Talkative, & Lively (Teen Titans)
Although he's happy to play the clown, Beast Boy from the Teen Titans is still a clever and curious character who needs to rely on quick wit to effectively manage his superpower. His propensity for comedy is often for the sake of others since he enjoys making people laugh and dislikes being lonely, much like the Gemini zodiac sign. Like Gemini, Beast Boy is flexible, open-minded, and willing to give people the benefit of the doubt, as evidenced when he trusted Terra despite her suspicious nature.
9 CANCER: Katara Is Protective, Sensitive, & Emotional (Avatar: The Last Airbender)
Perhaps it's because Avatar: The Last Airbender's Katara became a surrogate mother for Sokka after their tribe was attacked, but she grew up to have the maternal and occasionally smothering traits that are typical for Cancer zodiacs. She's also quite resentful and has been shown to hold a grudge on at least one occasion, but as evidenced with Zuko, she's not against changing her mind once her sympathies are roused. Her kind, nurturing personality easily aligns her with the astrological sign Cancer.
8 LEO: Kim Possible Is Proud, Reliable, & Cheerful (Kim Possible)
A natural-born leader, Kim Possible's titular hero has a positive outlook that easily fits in with Leos in the zodiac. She's assertive and confident but can also suffer from insecurities and pressures to fit in, a common contradiction that Leos also have to deal with. Nevertheless, Kim's capable attitude leads her to accomplish great things throughout the series with an indomitable spirit that's the envy of those around her. She takes her work as a hero seriously and strives to protect others with a lion's ferocity.
7 VIRGO: Double D Is Analytical, Rational, & Meticulous (Ed, Edd n Eddy)
Edd from Ed, Edd n Eddy fits Virgo's description to a tee with his fussy, high-strung personality and strict adherence to rules and procedure. Like Virgo, Double D is also friendly and willing to cooperate with others as long as they don’t aggravate his fault-finding nature, in which case he will quickly correct them with their best interests at heart. He's a skilled architect that forms the backbone of his group's operations and they'd be helpless without his diligence and foresight.
6 LIBRA: Aang Is Diplomatic, Charming, & Tactful (Avatar: The Last Airbender)
Aang's inclination towards peace, balance, and harmony neatly aligns him with some of Libra's more famous traits. He's also got Libra's tendency to be indecisive and uncommitted, as evidenced when he initially runs away from his responsibilities as the Avatar.
But Aang's sense of fairness and impartial judgment make him a perfect match for the Avatar's responsibilities, a role that Libras could also easily take on. Once Libras do finally commit to a cause, they will act in the spirit of compromise and fairness, just like Aang.
5 SCORPIO: Raven Is Secretive, Brooding, & Serious (Teen Titans)
In Raven's defense, it's important for her to have a tight lid on her emotions, as they can easily spin out of control. This matches her with Scorpio nicely, since this zodiac sign is also prone to holding their true feelings inside or risk emotional explosions. Both Raven and astrological Scorpios also have suspicious, cautious natures that make it difficult for them to trust and open up. But once Scorpios devote themselves to something, they are steadfastly loyal and protective, a trait that Raven developed as she got closer to her teammates.
4 SAGITTARIUS: Lazlo Is Optimistic, Honest, & Restless (Camp Lazlo)
Lazlo's enthusiasm for adventure and excitement matches him quite well with Sagittarian qualities. Like Sagittarius, Lazlo has a passion for exploration and the outdoors that is unmatched by his fellow campers. He's also got the handy skill to turn a bad situation into a good one, something that Sagittarians excel at since they're always looking for the best in every situation. Lazlo also mirrors Sagittarius' lack of tact, as both Lazlo and Sagittarians are prone to speak before thinking. Nevertheless, Lazlo's devotion to freethinking aligns with Sagittarians nicely.
3 CAPRICORN: Nigel Uno Is Ambitious, Disciplined, & Responsible (Codename: Kids Next Door)
Also known as Numbuh 1, Nigel from Codename: Kids Next Door is the workaholic head operative of Sector V and leader of his team. Like Capricorns, Nigel is stern and goal-oriented with a strong sense of duty, and he's wholly dedicated to his role as a KND operative.
Capricorns are also steadfastly devoted to their work, making this zodiac sign a good fit. Nigel is practical and disciplined in his work yet still manages to have a good sense of humor despite it all, very much like an astrological Capricorn.
2 AQUARIUS: Dib Membrane Is Intelligent, Opinionated, & Fanatical (Invader Zim)
As Professor Membrane's son, Dib from Invader Zim has a natural proclivity for science and technology, traits that go quite well with the astrological sign Aquarius. He's a talented, brilliant kid for a 12-year-old, easily making him stand out from his peers. Unfortunately, this leads to him being frequently misunderstood, and Dib suffers as a rebellious loner. Despite this, he starts off the series with idealistic determination to save humanity from Zim's treachery, marking him as a humanitarian – another attribute commonly associated with Aquarians.
1 PISCES: Bubbles Is Compassionate, Kind, & Intuitive (Powerpuff Girls)
Bubbles from the Powerpuff Girls demonstrates a keen empathy that allows her to get along with nearly anyone in Townsville. She's also the only one of her sisters who is comfortable sharing and being honest about her feelings since she tends to have sympathy for others unless they've thoroughly proven they're rotten. On the other hand, she's also prone to being overly emotional and impressionable, traits that have led to her being deceived in the series. But overall, Bubbles is a creative and generous girl who just wants to spread happiness.
