Bolin is one of the main characters of The Legend of Korra, the sequel series to Avatar: The Last Airbender.
Bolin, a skilled earthbender, grew up on the streets of Republic City, United Republic with his brother, Mako, after their parents were murdered. The brothers' lives took a turn for the better when, during their late teens, they met Avatar Korra, who joined their Pro-bending team. They then formed the new Team Avatar and ended up putting a stop to a corrupt group known as the Equalists.
During the next several years, Bolin accomplished many things, both on his own and alongside his teammates. Some notable solo accomplishments include starring in a series of propaganda films as "Nuktuk: Hero of the South," saving the president of Republic City from a kidnapping, and becoming a corporal in an Earth Kingdom military force. One of his most impressive traits is his ability to lavabend, discovered by accident at the age of 17, which is an extremely rare sub-form of earthbending that allows the user to manipulate and create molten lava. At the moment, he's in a romantic relationship with an airbending woman named Opal.
