Jade Shark Named so for their leader, Jet, the goal of the Jade Shark is simple: eradicate all benders.
Straightforward as the purpose may be, accomplishing that objective has proven more than difficult. For the most part, the Jade Shark is not a methodical and organized group so much as a collection of rebels with a common goal who offer some allegiance to their leader--and only their leader.
They tend to be reckless, brash, and more often 'every man for themselves' in a battle of survival, given that they flock in the very pit of Ba Sing Se. The underground enjoys a loose semblance of order under Jet's rule, and their technological base in Si Wong works like a well-oiled machine, but the rest are prone to blitz attacks, scuffles, and various other ways of not always staying under the radar. But what the group lacks in solidarity, they more than make up for with ingenuity, craftiness, and sheer drive.
They rely on their technology and cunning, and the plans they do form generally take a very long time to put into motion; any 'flash in the pan' stunts typically turn out catastrophic for them. Their one true goal is paramount, just as the word of their one leader is gospel, and they're more like a cult than a gang for how staunchly they'll hold to their beliefs.
But everything requires money to grease the wheels, and their technological finds are no different. They depend on financiers - the shadier the better - and a current illegal slave and drug trade that runs through the Avatar World. While it might be hard to notice at first, higher-ups in the nations may actually own slaves who are affiliated with the Jade Shark. Most Jade Shark slaves are kidnapped fire benders, but other bending persuasions are fair game.
Currently, the Jade Shark has plans to create a way to permanently block bending--having already adapted the chi blocking techniques known by the likes of Ty Lee to suit their needs. They aim to harness the residual power of energybending unleashed by Aang on Ozai in the final battle, hoping to find some secret to that art in the very stones of the terrain itself. Their cover, unfortunately, is slipping; their endeavors in chemical warfare resulted in the plague currently ravaging Ba Sing Se and outlying lands, and their destruction of the Southern Air Temple is sure to bring about an investigation.
