Hate Sink

4 vs. Satan:
* Freezer and Devontres, who belittle the hero and turn out to be mass-murderers. When you can finally fight them, their defeat will be catharthic.
* Jeremias, the leader of the helpers. While he seems to be friendly at first, he later insults the main characters and belittles the others when they fail. To defeat this dude is satisfying.
Alex in Princess Quest:
* NONE
The Stone of Power:
* While Artimus is too sympathetic, his brother Balthar by the end of the game is pretty much the one the player would beat up for his actions. He only cares about the legacy of his family and would wipe out a town just to demonstrate his power.
The Three Kingdoms
* King Vlados Palerius, who's pretty much everything wrong with high-ranked people, who has cities massacred and only wants to get rich.
Dragondawn
* While the dragons are more a threat than someone to hate and the chapter-bosses aren't well-developed, Judge Oscar, who repeatedly belittles the hero might count. The player likely won't cry when s/he finds out one of the dragons killed him along with everyone in the headquarters.
Harter Knall
* King Greyland who's corruption and greed incarnate and has people executed for not giving him enough taxes.
Hero Story
* NONE
Kill the Demons
* NONE
Satan Saga
* Pope Bonmos, who outright gasses criminals and destroys towns when one of them hates him.
Story of Hero:
* Elizon Tataros who has his brother killed for the throne and sees his people as nothing more than tools.
The Legend of Devils
* NONE
The Sidestory Duology:
* NONE
The Time Of Bloody Fear:
* N/A
