Naturally, there are more than a few horrifying moments across the story.
Arc One
- Colonel West. A blood-thirsty, deranged, ruthless soldier, he orchestrates the events of the first arc for the sheer fun of it.
Arc Two
- Wake the Snake. A relatively harmless Stand... until its owner's inability to control it causes it to mutate into an out-of-control animal rampaging through Ashford. Anyone bitten by it will die if they fall asleep, and Mao happens to be on hand to ensure the body count rises.
- Mao gets control of Anubis. It upgrades his power to levels of long-distance attacks, while keeping him from being harmed by anyone in the room. And he takes Nunnally, Zero, and Cornelia hostage.
Arc Three
- The High Eunuchs are all vampires, and their grand scheme is to retrieve Kars.
- Kallen's brother Naoto reappears. Bad news: he's a zombie. Worse news: he wants to make the Black Knights undead and conquer Britannia, subjecting them to the same atrocities the Japanese were put through. Horrible news: he arrives in the Guren S.E.I.T.E.N., the strongest Knightmare Frame from canon (besides Lancelot Albion) and so far above what anyone else can bring on the field that it's an honest surprise to Lelouch that there's nothing supernatural about the machine's design. Time to panic.
Arc Four
- Dio casually threatens to launch ten F.L.E.I.J.A. at Korea in retaliation for the Black Knights invasion of Tokyo. Only his audience's unfamiliarity with the term stops them from panicking.
Arc Five
- Schneizel's awakening. A vampire capable of manipulating the speed of light to not only melt in the sun, but even to effectively see into the future by speeding up the speed of light. He quickly proves the most dangerous fight the heroes have had yet.
