Blood Brothers Gang is a vampire gang that commits more crimes than most others.
This gang is extremely ruthless and commits all sorts of crimes for survival, and will take in any vampire member. Roberto Esparza seems to be a key member of the gang.
When Shadow Falls Camp Academy was first established, the gang feels it is corrupting and diminishing their potential members, and attempts to shut it down by killing animals at the nearby wildlife park and placing a lion in someone's cabin. They also went to the limit by kidnapping one of the camp leaders' sister for leverage. Their plan is eventually spoiled.
