STAGE HAZARDS
* If your user icon is a character that appeared at Comic-Con, then you get a power-up bonus that doubles your attack power. However, this is a double-edged sword: If you cause too much property damage at Comic-Con, not only will you automatically lose the power-up but the fans of the character that your user icon is based on will turn on you and attack you.
* Security guards
* Actual superheroes and supervillians who are enjoying their fanbases and are pretending to be ordinary people in costumes.
