Fanatics, otherwise known as Zealots are people highly devoted to religious, political and ideological causes to oppressive and extreme degrees. They are one of the most dangerous characters the protagonists have to face since they believe everything they do, no matter how horrendous can somehow be morally justified.

They often play the victim (or more specifically the martyr) when their deeds are exposed and brainwash others into believing only their beliefs are correct and make Scapegoats out of those who don't agree with their beliefs as being ironically evil and conspiring to destroy or kill them. They are extremely defensive, watchful and willing to commit horrendous acts of violence (including terrorism) to preserve their beliefs from "enemies".

In many cases Fanatics may be rogue elements, not being good representatives of their respective beliefs and doing things that would normally be considered wrong by their own belief systems yet finding ways around it by using the same system.
