An efficient villian would ensure to DO the main character's mother before dying.

I would be a boss standing in a plain concrete room with no windows and no music. My only weapons a knife and freezing time indefinetly for everyone except myself.

Haha yup i love it!

Mine would be the theme song to Friends. Over and over and over.

I would punch people and they would explode into a green ooze. Then I would eat the green ooze and shit them out and the mortal combat fatality music que would play.

Shouldn't this thread have gotten more attention? Let's revive it.

I would allow my design to be outsourced, Human Revolution style, to the bemusement of all. I like the guessing game involved; so what if MW3's final battle is against a horny dragon?

First thing I'd do as a Final Boss is erase all the Player's Save Files. Just because I have to show that person that they're dealing with an entirely different level of evil than anticipated. Then I'd force Player 1 to face Player 2 (and perhaps players 3-8 if online) in a massive environment-destroying battle royale to determine which has the honour of facing and ultimately being defeated by me. At this point the sole survivor should be suffering from a lack of ammo or potions or whatnot, making him worthy of facing my Secondary Form. Which would be an enormous walking Necro-Cybernetic factory to produce an endless wave of enemies while the unfortunate hero scrambles up my form Shadow of the Colossus-style while being assaulted from every angle by my personal defenses. Thirty minutes of destroying key sections of my form defeats it, but my consciousness is downloaded into a prototype ubermech 5X stronger and faster than any other enemy in the game with over a dozen different specialized ranged attacks. Two Steps From Hell makes the music for this fight. My defeat results in a heart-wrenching cinematic that makes the Player feel bad for fighting me. But doing so on the hardest difficulty unlocks a code for free DLC to unlock the Villain Playthrough where they play as the Final Boss through its perspective of the story, revealing the original protagonist to be the true villain all along.

All I've got is music. Sorry.

Well, I'd...

1- Be Immortal

2- Never get tired

3- Have a devil wing in my back on the right, and an angel wing in my back on the left, which I keep invisible most of the time (both of them)

4- Make all my attacks with the right hand, leg, eye, etc and all defenses with the left hand, leg, eye, etc.

5- Be Faster than the speed of light^65536, with proper reflexes.

6- Control people and objects (like planets or even stuff like stars or galaxies and dimensions) at will.

7- Teleport wherever I want.

8- Be able to go through everything as if I was a ghost.

9- Kill stuff just by thinking of it (for example, make every living creature on the planet blow up in a million pieces at the same time if I feel like it), revive stuff just by thinking of it, destroy or create/re-construct stuff just by thinking of it (Like making every planet in space blow up if I feel like it or re-create them later if I want to).

10- Know everything that happens in the present and will happen in the future, know what everything and everyone is thinking, doing, will do, etc.

11- Travel through time, being in different times at the same time without having to leave the present.

12- Be able to turn into full demon or full angel form whenever I feel like it

13- Make as many copies of myself as I want, with the same powers I have. Make them return to my body when I want to.

14- Modify creatures and stuff from the universe at will.

15- Have infinite strength

16- Be immune to wounds, can't get hurt, don't age unless I want to

I want the "hero" to be exactly like me, with all the same powers I have...

However, 6 doesn't work on me, in 9, only the "kill stuff just by thinking of it" part doesn't work on me, in 10, no one can read my mind or know what I'll do, 14 doesn't work on me.

The same goes for the hero ( 6 doesn't work on him, in 9, only the "kill stuff just by thinking of it" part doesn't work on him, in 10, no one can read his mind or know what he'll do, 14 doesn't work on him.)

We both exist at all times at our current age (we exist now, 1 second ago, 1 year ago, 99999999999999999 years ago, at the very beginning of time, 99999999999999999999 years in the future,  at our current age) and we share our knowledge through time as if we were experiencing the now, the past and the future at the same time.

Before the fight, we agree not to make copies of ourselves, we're going to fight 1 VS 1.

The reason I want the hero to have exactly the same abilities and powers I have and to make it 1 VS 1 is so the fight is as fair as possible... and the battle as enjoyable and epic as possible :P

It'll probably be a neverending fight and we'll probably end up destroying existense itself (we can recreate everyting anyways, so it doesn't really matter), only the 2 of us would remain, fighting for eternity... and our sole reason for living would be to fight one another and accomplish the impossible (beating the other one to become the strongest being in existence).

Yeah, I have nothing better to do right now :P
