Before we start the list, I shoud probably take a minute to define exactly what a prefabricated villain is, huh? Well, it’s pretty simple, really. A prefab villian is an adversary that you’ve never seen before, and who is designed and introduced for a very specific reason, usually to be the “ultimate enemy” of a hero or team of heroes.
So, we’ll start the countdown with my personal favorite, and one that really sort of pioneers the formula and sets the stage for those to come…
The Fury

First Appearance: Marvel Superheroes # 387
Originally, I’d thought about putting the Fury on my list of supervillains that just scare the bejeezus out of me, but I think he fits here okay.
Introduced by Alan Moore and Alan Davis (“The Alans”) in the pages of Captain Britan, the Fury is an emotionless and unstoppable engine of destruction designed to kill Earth-238’s super-powered population… and later on, the superheroes of all other Earths.
“What’s the Fury’s deal?”
It kills super-heroes.
Literally.
And never has a single descriptive line for a villain been more appropriate … well, except for maybe DC’s Kobra, but that’s another list.
The Fury was created by ”Mad” Jim Jaspers, a reality warping mutant from parrallel Earth-238. Jaspers had used his power to garner a Parlimentary position, and initiated a number of superhero regulatory programs. He engineered the “cybiote” Fury to police his policies, and later on, after outlawing all superhumans, programed it to kill them — all of them – with the only exception being himself, of course. When its mission was complete, Jaspers shut down the Fury and began ruling the world as he saw fit.
But then, while on a mission for Merlyn, Captain Britain materialises on Earth-238. With new heroes alive and well on its planet, the Fury is reactivated… and KILLS Captain Britain.

Seriously… breaks his arm and then barbeques his ass.
When Merlyn realizes what’s happend to his champion, he retrieves Cap’s remains and is able to bring him back to life, better than ever. But even in Merlyn’s mystical Otherworld, the Fury is such a badass that he’s able to pick up the Captain’s life signs and adapt itself for interdimensional travel, leaving Earth-238 behind in hot pursuit… seconds before that reality is destroyed by cosmic overseers in an effort to keep Jaspers’ madness from spilling into other realities.
The Fury arrives on Earth-616 and finds Captain Britain battling that realities version of Mad Jim Jaspers… and believe it or not, this is where things go crazy in the story, as the Fury totally schools Captain Britain AGAIN, but doesn’t kill him. It redirects its focus on Jaspers, and realizes 616’s Jaspers isn’t its creator and is just another super-human. The Fury attacks without remorse, and the two of them tustle through a myriad of realities and worlds, in what is undoubtably one of the most amazingly bizarre battles you’ll ever read (I promise), before the Fury drops Jaspers off in what’s left of Earth-238… a place that’s esentially been wiped from existence, and making Jaspers reality warping powers utterly useless. There, the Fury kills him.
Even though it’s damaged in the battle with Jaspers, the Fury returns to 616 to finish off the Captain, but it doesn’t stand a chance against an army of Captain Britains — a band of displaced Caps from different realities — who beat it to death and dismantle it before it can regenerate and kill again.
“Why’s the Fury a Prefab Villain?”
While maybe not as prefab as some of the higher numbered creeps to come, the Fury works well on this list because its only purpose is to be an obstacle against which Captain Britain, with all his powers and abilities, doesn’t stand a chance. A menace so distant and mysterious, that even the jaded and experienced comics fan can’t quite predict the ending.
None of the Captain’s usual gang of nuanced psychos, like Hurricane or the Corruptor, would have worked. The story needed new blood to work; something that raised the ante enough to convince readers the Captain might actually not make it out of this one alive… and the Fury delivered.
