Johan is a member of the fearsome Four Major Crews and is the leader of the crew "God Dog". Jace has stated that Johan, unlike the other crews, never needed a right-hand man or extra muscle to back him up.[2] Johan's true potential was always held back because he did not want to cause trouble for his mom by fighting. However, he finally decided to reach his fighting potential in order to save his mom from being stoned to death during the Cult arc.
