I'm just looking for the generic evil MC who will do absolutely anything to reach his goals whether it's rape, plunder, murder, or treason. Already have read novels such as Reverend Insanity, Renegade Immortal, WMW, Carefree Path of Dreams, Mystical Journey, Way of the Devil, etc.. On a side note I remember there somebody suggesting a decent evil pokemon fanfic among others if anybody could help find that one it'd be appreciated thanks.
The only "evil" Pokemon fanfic that comes to mind is Regret (https://www.fanfiction.net/s/5808527/1/Regret). The MC isn't necessarily evil, but the story as a whole is a pretty dark and edgy take on Pokemon.
Already read Overlord and dense MC really isn't my cup of tea, I'll check out Youjo Senki when I have the time though thanks
Reverend Insanity: I don't really like the "power system" since you're just relying on these gu bug things, but the mc is pretty lawless.
