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: Prophesies Destinies And Killing Gods
Complete Monster: Kaine Heresy, Count of Crows. Murder, torture, rape, and complete mental annihilation are all merely games for him to play.
Omega generally came off as this, killing for fun and generally attempting to destroy the entire universe. He had a kill count at near the end of his campaign that was measured in planets.
Takamagahara may be seen as one of these. He harvests the souls of entire planets, converts humans into robots, and is generally willing to do anything.
Ho Yay: Will flirting with Viola, a.k.a Rawk in female form. While Will was unaware it was Rawk, Rawk opted not to refuse his invitation to dinner.
Stoic Woobie: Ray. His wife got addicted to a drug called arrakeen, and when he refused to support her habit, she turned to prostitution to pay for it, eventually dying of an overdose. He avoided smiling for a long time after that, but has slowly become more open thanks to Arte.
The Woobie: Flora. A sweet thirteen year old girl with a big heart and an adorable stutter, one already wants to hug her. This is not helped by the fact that she was also kidnapped at the age of six and broken in every imaginable way until being sold as a sex slave at the age of eight.
