The Black Vipers are a motorcycle gang living in Texas. Their first and so far only appearance has been in the episode The Black Vipers.
It is led by Clay Bailey's sister, Jessie Bailey. It is an all-girl gang of motorcyclists with not much known information. They steal Wu from Clay and the monks and at first appear to be ruthless. After the episode, Jesse returned the Shen Gong Wu, all but one. She kept the Wings of Tinabi for her own entertainment.
Besides Jessie, there are other 3 members in the gang. The only one of them with a known name is Belle, who is listed in the credits and is also identified on concept art.
