These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Power Of Five
Complete Monster: Colton Banes stands out as especially vile - when not killing and torturing for Nightrise, he lives in a disgusting trailer where he keeps a drugged and abused young woman. And yes, that last part is as bad as it sounds. He gets a well deserved come-uppance. The bastard.
Susan Mortlake starts to seem like this when the reader gets to see flashbacks of what she did to Scott. Of course, by then we've already seen her get a bullet in the face, which makes it easier.
Everyone Is Jesus in Purgatory: Matt's story is suspiciously similar to the life of Jesus Christ. Born with special powers according to some higher plan, destined to save the world from The Legions of Hell and their very Satan-like leader, leads a small group of followers of whom the closest to him is named Pedro ('Peter' in Spanish), accepts his destiny despite wishing there was another way, betrayed by one of his companions, flogged and beaten and hung up to be jeered at, died, came back and ascended to Heaven right in front of his friends.
Magnificent Bastard: The world's magnificent bastards are working for the Nexus: Shang Tsung, a ruthless Asian crime lord, a DGSE spy and a not-so-subtle Rupert Murdoch analogue, are both the villains of another story, but here are vital warriors on the side of good.
Tear Jerker: What Richard eventually uses the tumi for... And Matt knew it was coming ever since he read his own book.
Stoic Woobie: Matt again, by the last book. Also Pedro, who never really complains despite being a starving street urchin who spends most of his pagetime being hunted, abused, betrayed, nearly killed on several occasions and repeatedly exhausting himself trying to use his power on grievously-injured people who often don't make it anyway.
Uncanny Valley: Shape changers pretending to be humans have this effect. Of the few that are mentioned, not a single one has maintained their deception for any length of time: One lets his disguise slip when he meets Scarlett, the other has a freakishly round head, one can't speak, one doesn't notice cutting his own thumb off, and one doesn't notice an enormous insect crawling over his eye. The best impersonation so far has been "Audrey Cheng", and even it gave the game away when it forgot to eat. Scarlett rumbled it when she realized the only time she had ever seen "her" express hunger was looking at a fishmonger's slab.
