Water bending is inside those born under the Cancer sign, so they don't have to seek far. Cancer signals include emotional depth as well as a loving character. Water benders, as seen in Avatar: The Last Airbender, have a profound awareness of nature and the emotions of those around them. They can also be viewed as having a great deal of integrity since airbending and waterbending are not easily mastered techniques; instead, they are natural talents that take practice but come naturally to those who are born with it. Cancers are also known for being loyal and trustworthy. Water benders are born under the sign of loyalty, which explains why Ozai was able to find such talented students among the children of the four nations. Cancers are also known for their love of family, so it isn't surprising that all of Ozai's students were from Cancer families. Cancers are sentimental by nature, which is another reason they are good at finding talent within others. Finally, cancers are practical people who know how to get things done. They may not use modern tools or technology, but when necessary, Cancers will go out and find other people who can help them achieve their goals. Benders are known for coming in pairs. Together, they make one powerful source of energy that is capable of amazing feats.
