The Black Family
In the summer of 2008, it looked like there was rift growing in between La Secta leader El Mesias and Ozz. This would come to a head when El Mesias was booted from La Secta in September 2008 for losing to long-time rival Vampiro in a cage match. Since that point Ozz took control of the rest of the Dark Family to remake that stable from the rubble that was La Secta.
Former member Chessman and Charly Manson have been teased as rejoining their old group. Chessman turned on the Dark Family in favor of aligning with Psycho Circus, so that's out.
