The group was formed by Sentenz to fight crime in the city and are not associated with the police. Sentenz e-mails the Liberty Tree newspaper to defend the Avenging Angels, saying that they have a positive influence on the city. He admits that some mistakes have been made, citing the death of an elderly lady who they believed was a drug dealer. By 2001, the group had been disbanded in Liberty City. Sentenz also claims to have a black belt in kung fu.
- Sentenz's surname sounds similar to the word "sentence", likely an allusion to the fact that he issues his own "sentences" (punishments) to criminals and suspected criminals.
