YMMV / Negativetale

• Complete Monster:
  • Asgore Dreemurr is reimagined as a ruthless misanthropic tyrant who seeks to dominate the human world along with his own. Transforming the underground into a hierarchy where only the strong can survive, when the first fallen human, Chara, falls into the underground and acts as if they hate humanity as much as he does, he takes them under his wing, planning to use them to cross onto the surface and achieve dominion over it. When Chara breaks down crying after Asgore forces them to execute several monsters who are considered weak, Asgore, in a fit of rage, murders them before forcing his son Asriel to absorb their soul, cross the barrier, and kill six more children. When Asriel fails, Asgore places a bounty on Asriel, now Flowey's, head, ordering him to be killed for his "injustice" before isolating himself away from the outside world out of shame for failing in his goals. In the present, Asgore has managed to corrupt the underground to a point of no return, with all of the monsters becoming horrible killers while he himself waits patiently for his next victim to come wandering in. When the human child Frisk comes in to face him, Asgore attempts to kill them in order to get the last push needed to break the barrier, only to be stopped and promptly killed by Flowey. In one last-ditch effort to secure victory, Asgore attempts to absorb Frisk's soul in order to take it over and use them to cross onto the surface, leaving Flowey having to regrettably kill them in order to stop him from accomplishing his goals.
  • Alphys is portrayed in a far more sinister light in this comic when in comparison to canon. A mad, egotistical scientist working as The Dragon to Asgore purely for her own personal gain, Alphys provides him with gadgets that allow him to turn live monsters into killing machines, with the determined Undyne being a victim of such, turning her into a mindless droid with no free will of her own. When Frisk enters the picture, Alphys begins to monitor them, studying and observing them to use for presumably malicious purposes. Upon the intervention of Mettaton, one of her rogue creations. Alphys would proceed to egg him on with insults and allowing him to be broadcasted all throughout the underground for the sole purpose of the audience insulting him to the point of ending his own life in one last desperate plea for fame, with her fully admitting to "partially" knowing the outcome of the stunt afterwards.
• Magnificent Bastard: Sans the Skeleton proves himself to be one of the lesser evils within the underground. Growing resentful of his brother Papyrus for his constant abuse, he plots a scheme to take him out for good. Manipulating the fallen child Frisk into following his lead before telling Papyrus of their approach, he strikes his brother down mid-battle, killing him and effectively pinning the blame on the human. Spending the rest of the comic showing off his skills as an expert conman and pickpocket, Sans manages to evade consequences for his actions, getting away with his crimes and being one of the few characters who manages to make it out alive in the end.
