Born in the Northern Water tribe, Hong was gifted with two water-bending parents. His father Ravi was a chief police officer while his mother Tena was an average healer. His parents had met in a crime scene, and the two had their son after two years of courtship and a year of marriage. Desiring their son to be great, they uniquely named him "Hong," meaning "magnificent." A year later, Ravi and Tena gave birth to a baby girl and named her Huan ("joy").
For seven years, Hong had a normal commoner's childhood. During the day, he would attend school. After school, he and Huan would help their mother with the house chores. Since Hong adored learning, his mother would often buy the boy books. Due to work, Hong's father rarely spent time with his children; however, when Ravi could, the whole family would play ball in the park. For short, everything was well.
When Hong was seven years old, his parents knew it was high time to test their children's abilities. The family visited the river bank. At the command of their father, the two children exercised their talents. While Huan drenched her father with a water wave, Hong froze his mother's water whip. After that day, the two children were given more than proper training. Days and months passed with little trouble.
At the age of twelve, Hong's life was changed. When his playful sister entered the portal to the Wastes, Hong followed. Huan insisted on exploring the area, much to Hong's disliking. Being unable to convince his sister, Hong noticed they were being followed; howbeit, it was too late. When a few adults caught up to the situation, the pirates planned to take at least one of the children away. Being a good brother, Hong shoved Huan away and took her place. Hong was sold into Republic City.
In the foreign place, Hong was bought by the wealthy Zhang family. The masters abused their powers, and Hong was a witness to their horrid works; the boy was also shocked at the police officers who were actually conniving alongside his morbid masters: secret murders, gang rapes, and more atrocities were done inside the manor's walls. Sometimes, Hong would be victimized by the master's wife; however, despite his utmost disgust, the waterbender retained his sanity. Hong's job was to feed the hostages and rid the floor of blood. Whenever Hong tried to protect a victim, he was beaten and stripped of dinner; the repeated beatings taught Hong to subtly help the captives instead. During times of pain, Hong would secretly read, and he would be at ease.
After two and a half years, Hong was able to escape. He packed his belongings and purse of money. With only a few places to run to, Hong wandered to the slums. A boy his age took him in their home. There were a few nights where he had little to eat, yet Hong was grateful for every grain of rice. The water bender would be a part-time waiter, hoping to shoulder a few expenses around the house. Things were worse when police officers often knocked on their door asking for money; unless the family wanted trouble, they had to donate a few yuan.
Currently, the seventeen-year-old Hong lives in the Republic City slums with his companion Yuki. He currently works as an apprentice doctor in the Republic City Medical Center and member of Faceless, hoping to overthrow corruption.
