An antagonist hero or heroic antagonist is a character who is in the opposition to the protagonist, yet is heroic in nature; this is usually due to the protagonist being a villain protagonist, and not the "anti–hero" type either, but a true villain, but there are also conflicts where both the protagonist and the antagonist are heroes. In short, antagonist heroes are heroes who oppose the protagonist, whether good or evil.

For obvious reasons, these characters are rarely Pure Good since it is not common in many works for an opposing character to actually be Pure Good, though there are some huge exceptions if they completely lack any corrupting qualities and the other characters are visibly pleased or comforted by their actions. Mister Rogers, Spider-Man, Cabba are good examples.

Note: Do NOT add heroes who oppose other heroes to this list. Save that for Good vs. Good.

They are the exact inverted opposite of villainous protagonists
