Deals with obsessive desire to protect others (those dear to the character, those who can't defend themselves, or even everyone). Often the protagonist has this, but can include any major character.
The first video game about Protection complex was released on January 31, 1999.
Usually big brother, big sister, or somewhat more rarely a parent is the one who does this. If this goes too far, the character is blamed of being overprotective in negative (rather than fond) manner.
Makes sense in case of close family, but when you break laws, ignore morals, endanger others for sake of the ones you care for, fight monsters, armies, forces of nature, and so forth to do it, something is not quite normal or right.
