Forum:Blood-Types Personality of characters

About This:

From Wikipedia:

"Discussion of blood types is widely popular in women's magazines as a way of gauging relationship compatibility with a potential or current partner. Morning television shows feature blood type horoscopes, and similar horoscopes are published daily in newspapers. In addition, a series of four books that describe people's character by blood type ranked third, fourth, fifth and ninth on a list of best selling books in Japan in 2008 compiled by Tohan Corporation.

Although there is no proven correlation between blood type and personality, it remains popular with the many matchmaking services that cater to blood type. In this way, it is similar to the use of astrological signs in the west, which is also popular in Japan. Asking one's blood type is common in Japan, and people are often surprised when a non-Japanese does not know his or her own blood type.

Many idols, tarento and other Japanese celebrities include a blood type statistic in their profiles, in addition to other facts such as their hobbies and star sign.

It is common among anime and manga authors to mention their character's blood types, and to give their characters corresponding blood types to match their personalities. Some video game characters also have known blood types, such as in the Street Fighter series, the King of Fighters series, the Soul series, the Final Fantasy series, the Resident Evil series, the Melty Blood series, the Guilty Gear series, and the Dead or Alive series, which lists character blood types in both the manual and in-game biographies. In addition, it is common for video game series, such as Gungriffon, Tekken, Metal Gear Solid 2, Princess Maker and Loveplus to allow for blood type as an option in their creation modes."

I was wondering why bleach characters have blood-types known, I searched and saw this: They call it Blood-type personality or Blood-type horoscope.

Blood Type A
People with blood type A have a deep-rooted strength that helps them stay calm in a crisis when everyone else is panicking. However, they tend to avoid confrontation, and feel very uncomfortable around people. A types are shy and sometimes withdrawn. They seek harmony and are very polite, but all the same feel that they never really fit in with others. A types are very responsible. If there is a job to be done, they prefer to take care of it themselves. These people crave success and are perfectionists. They are also very creative, and the most artistic of all the blood types, most likely because of their sensitivity.

People with blood type A are also likely to be considered classic "type A's": stressed and conscientious.

 * Sado Yasutora

Blood Type B
People with blood type B are the most practical of the blood groups. They are specialists in what they do. When they start a project, they spend extra time understanding and trying to follow directions than others might. When they are doing something, all of their attention is focused on it. They tend to stick to a goal and follow it through to the end, even if it seems impossible. They tend to be less than cooperative, as they like to follow their own rules and their own ideas. They are individualists. B type people pay attention to their thoughts a little more than their feelings, and therefore can sometimes seem cold and serious.

People with blood type B are often considered more relaxed, freewheeling, and unconventional than other types, although not necessarily to an unacceptable degree. In anime, the off-the-wall types are type B, along with any kind of well-intended character who's ruled by their impulses.

Blood Type O
People with blood type O people are outgoing, energetic and social. They are the most flexible of the blood types. They easily start up projects but often have trouble following through because they give up easily. They are flighty and not too dependable. O types always say what's on their mind. They value the opinion of others and like to be the center of attention. Also, people with O blood are extremely self-confident.

Type O, the most "average" blood type, is considered the best type in Japan.

Blood Type AB
People with blood type AB are hard to categorize. They can have characteristics on both ends of the spectrum at the same time. For instance, they are both shy and outgoing. They easily switch from one opposite to another. AB people are trustworthy and responsible, but can't handle it when too much is asked of them. They don't mind doing favors or helping out, as long as its on their own conditions. People with this blood type are interested in art and metaphysics.

AB is considered the worst blood type. In predictability-loving Japan, they're loose cannons. They also like to set their own conditions and reserve the right to drop out when things don't meet their expectations. They're known to be sensitive and considerate—at times—but it just isn't enough to balance out the flaws in this blood type. For a while, some companies tried dividing their employees into work groups based on blood type, and no one wanted to work with the AB group. Anime villains are likely to be type AB.
