Red Right Hand

This quasi-cult organization was formed by survivors whom blamed Wolverine for the loss of their loved ones, legitimately or otherwise. Their inner circle orchestrated an elaborate conspiracy with an opening gambit to send Wolverine's soul to Hell and have a cadre of demons possess his body on Earth, killing all his associates. This was done for the sole purpose of pissing Logan off to the point where he carved his way through the Red Right Hand's enforcers, the Mongrels, to reach the inner circle. Instead, the Red Right Hand's leaders all committed suicide to deprive Logan of the joy of killing them, and revealed that the Mongrels he had just killed were in fact his own forgotten children, born of his various casual encounters around the world.
