- The B-M themselves are bad enough, until you realize that their teeth (which are all molars) don't rip off chunks of flesh from their victims, like say, a piranha. They can only latch on, and chew them to death, meaning that you feel every single second of them eating you, up until they swallow whatever piece of you they succeed in chewing off, and they eat everything. If you're attacked by a huge swarm, quick death. However, when you're only attacked by a small handful, your death will be an agonizingly slow. Worse, either due to shock, or some manner of numbing effect from their bites, most victims don't initially seem to feel pain from the first few bites, so many victims only seem to realize something is wrong until they look down and see a B-M, happily chewing away on their sweet, sweet flesh.
- And then we have America's version, which can infiltrate just about any space, including you, and pull a Chest Burster once you cave into your need for water. Oh, and it's a tentacle monster.
- Furthermore, Shingo, when he feels like it. Holding a gun to his face? Fine. He'll give you a perfectly calm death smile, and terrify you into surrender.
- There's a good amount of horror actually, and notable in that, for the most part, it manages to creep the Dickens out of you without resorting to anything graphic. The ending to the chapter Contract, for example, ranks as one of the most horrific moments in the book.
- The beginning of the second outbreak. Just imagine you being saved in a lockdown building from tentacled monster, that grows before your eyes, by a bunch of soldiers, and few hours later, the same soldiers come back to BURN YOU ALIVE for witnessing it.
- The name Bio Meat should tell you all you need to know about the genre of this series. This ain't no Lucky Star, this ain't no Strawberry Marshmallow, this ain't no foolin' around...
- The fact that the outbreaks happen over and over and OVER. The Bio-Meat is simply too valuable to abandon, but no matter what ridiculous amount of precautions are taken, something always goes wrong eventually, usually due to human error or stupdity. The first two outbreaks were bad enough, but the third one basically wiped out all of Japan.
- The general of Conquest, the alleged La Résistance, after he goes insane and tries to kill all his "traitor" comrades for not beliving in their leaders (who turns out to be a bunch of rich kids who were just funding the group out of boredom).
- It's almost unnoticeable and left untranslated but one of the casualties involves a car with a Baby on Board sticker on it.
