I'm looking for any novel (translated, original, fanfic, quest, etc.) where an antagonist makes the huge mistake of making the protagonist angry or messing with his/her loved ones. I'm not talking about the normal you f*cked up. I'm talking about the an MC who's has unmatched power along with absolute ruthlessness. I'm talking about the MC being a John Wick that has the backing of the Illuminati as well as being a God Eldritch Abomination level being. That moment where you the reader knows that the antagonist and all he/she holds dear is already set to be wiped from existence.
Huh. ... Well, I guess you could go with Emperor's Domination. Basically every antagonist in the entire novel is like that -- totally fucked from the moment they cross the MC. The reasons range from causing serious trouble for people passingly acquainted with the MC to just so happening to be standing in the wrong place at the wrong time. I mean, if the importance is on the fact that the MC is OP as all hell.. Not sure about any loved ones, though. That guy is a bit eccentric. Library of Heaven's Path does the whole "suddenly the whole world is your enemy" thing a couple of times. I mean, the MC's influence in the world grows at a rather ridiculous pace, to rather ridiculous heights. Plus he sort of gains a cult-like following literally everywhere he goes. So after a point, being his enemy automatically means being enemies with quite a few other people. Often to someone's shock and confusion. The closest relations of his to be threatened are his students, though.
Naw it was the author who fucked the readers and he did not wear a condom or even give a courtesy lick
The Death Mage that doesn’t want a fourth time definitely applies to this (https://www.novelupdates.com/series/the-death-mage-who-doesnt-want-a-fourth-time/). Though it scales up when dispatching some “assassins” in Talosheim, MC does imprison the souls of some jerks who sold out his mother earlier on. Note MC isn’t OP from the beginning but he gets there (but he is certainly OP within his age range from the moment of his birth).
Ugh, I read a bit of that one and it is brutal in the sense that I can hardly understand the way in which the main character explains shit. Then again it might be a cultural discrepancy.
Arifureta The climax part is like this Spoiler Yue's got kidnapped by fake god, Hajime turn batshit and trying to destroy every existence
MGA “Why did you harm her, how could you dare to harm her?” “There will be, one day, when this sky shatters because of me, when this land collapses because of me, when the sun, moon, and stars change because of me.” “If that day, the one I love is no longer here, then I will make this world’s people die with her!”
Cultivation Chat Group. Messed with Song Shuhang, and bad luck will follow you. And its at least by the scale of 100× worse than what you did to him.
