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.
The Crax (a horrible parasitic being that devours its victims' minds and bodies) is revealed to be the vehicle of the consciousness of a man who wanted to live forever— by eating everyone else.
Derek, a magic user who would force other magic users (usually girls, apparently) into turning themselves into statues which he then collected (he got what was coming to him, though).
The "Messenger of Death" arc involved a killer shaman hunting other shamans by plunging them into absolute nightmares.
Growing the Beard: The strip began as a Gender Bender-centered one-shot for the predecessor of 910CMX, and the apparent hasty writing of the first half of the first chapter reflects this. As the author begins fleshing out the world, the comic gets much more interesting.
High Octane Nightmare Fuel: When Mori's last name is destroyed, we get a glimpse of what that truly means. The real question is, is this Mind Rape on a small child, or something far more widespread?
Idiot Ball: The Doctors' mishandling of the Valley case. Sarin justifies the mistake later by saying "Every good wizard needs to screw up once in a while, it keeps us humble."
Unfortunate Implications: By the truckload. In addition to the minefield that is this comic and gender (the phrase "gender identity can be surprisingly mutable at times" is actually said at one point, and the audience intended to agree), there's the fact that this society has reliable technology to change a person's sexual preference, which they use, essentially, to fill the world with lesbians.
More specifically, they have technology to enforce If Its You Its Ok and Situational Sexuality. The given situation involved a lot of lesbians, yes, but it's not a magic lesbianism pill.
Viewer Gender Confusion: Kittyhawk apparently thought that Mori was a large woman, even though being turned into a man early on is a plot point, at which time Mori's shirt breaks open. (This being well before she was turned into a large woman.)
