// They always seem to be beta males or girls who can't make up their minds. When they can make up their minds they are usually lowkey callous scum, which readers usually tolerate their reprobate actions to a certain degree.
// Usually, these characters have no clear goal or go off on terrible tangent arcs where they accomplish nothing. When they do have goals it is often some stupid carefree air-headed life goal. "I wanna run a bakery. Tee hee." "Slime farming." "Gotta grow and cook rice!" "I dun wanna be a corporate slave." Look buddy, you're in another universe now, I understand you wanna be lazy AF, but can you please take this seriously.
// They're so indecisive it hurts.
// Do they really have to be pacifists? "Oh, those slave traders are so mean to have just killed some children! But I can't kill them; I'm a pacifist. It's better if I give these evil men money for my slave waifu so that they can continue their lifelong trade of slavery, debauchery, and villainy. I don't wanna kill them because it's against the law in my new country that says slavery is A-OK."
// And when they aren't pacifists they are people like ex-yakuza or karate masters. People like the karate masters go from a mindset of "killing people is against the law" to "killing people is not against the law and I have no problem ending anyone's life now" in a few moments. Basically, the non-pacifists are usually high-functioning sociopaths that weren't free to murder before.
// A lot of these people are purported to be 'normal'. However, they are far more confident and capable at everything they do than 'normal' people would be. From my own experience, the difference between having casual knowledge about a subject and actually applying it to create something or accomplish something significant is a rocky path.
// They never have REAL mental breakdowns from being thrust into a different world. It's usually just a somber attitude, a little homesickness, and angst. If I was thrown into another world I would feel serious pressure and dread on my mind at all times. I would be thinking about god. What is reality? My soul? I'm terrified of enslavement magic, and all the sick things people might make me do.
