These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Skullmaster, the Evil OverlordBig Bad was always a terrifying villain whenever he appeared. Skullmaster overthrew his previous master and took control of his subterranean kingdom from where he plots world domination. Skullmaster is a sadist, reveling in physical and psychological torture, and engages in both short term brutality and long term gambits. One of his most vile acts was vowing to save an ancient civilization from sinking beneath the sea, lying about it and trapping their souls as his slaves before in present day, sending them after Max's head "attached to the body or not." Responsible for the deaths of multiple heroes throughout the story, Skullmaster even attempted to blackmail Max for his mentor and friend Virgil's life by surrendering his magical cap. When Max turned it over, Skullmaster brutally killed Virgil anyways.
Spike was a psychotic Blood Knight who definitely Would Hurt a Child. Ten Thousand years in the past, Spike led a pack of barbarians to attack a peaceful village when the heroic Norman was just a boy. Refusing offers of peace, Spike brutally attacked and killed Norman's unarmed father before attempting to kill Norman himself. Things went wrong and Spike was buried under the snow for the next 10,000 years, but not before gleefully saying he'd find the boy, kill him and eat his heart. In the present, Spike is no less savage and continues his battle with the now adult Norman until he is defeated. Spike is so evil that Norman feels absolutely fine killing him after Spike has already been defeated, and nobody bothers to complain.
Dr. MacDougal is the first fully human villain to qualify. A Mad Scientist who discovered the existence of werewolves, along with the fact they were peaceful guardians of Scotland.She captured the pack and hooked them up in a rather unpleasant situation where their blood was painfully extracted into a formula for her. After drinking it, Macdougal would achieve the ability to transform herself and used it solely to kill innocent people, becoming the scourge of the highlands. When Max, a ten year old, stumbled upon her lair, Macdougal locks him inside and takes her formula so she can kill him, gleefully referring to him as 'Breakfast.'
Hilarious in Hindsight: How does a race of highly evolved, technologically superior brain-sucking aliens store their plans for an invasion of earth? On a floppy disk. Said disk can also be reprogrammed (by a teenager no less) to cause the entire ship to self destruct, which sounds similar to a certain film that involved uploading a virus into an alien mothership.
