12. Code Geass

After the conquest by the Holy Britannian Empire with their powerful of Japan Lelouch is a Britannian prince who gave up his right to the throne after Citizens of rights and freedoms and renaming the nation Area 11.
It is always interesting when household matters mix. There are brand new robot weapons, the Knightmare Frames, stripping Japan, and even its own Code Geass is put in an alternate universe. This anime is quite a wild ride.
