There are certain unwritten rules that apply to the Avengers:
- The Earth's Mightiest Heroes are a united and unbeatable Unit.
- No intelligent foe would launch a direct assault on their Mansion
- Jarvis, the team's butler, is off limits to physical assault.
This is the story that breaks all the rules. You've been warned.
