The princess is in another castle, but enjoy the pudding

[Incredible Bullshitting Man]

A blow-up doll. He didn´t have a chance with the princess anyway.

Or a bagel, with a note saying:
"The princess took off with some lame hunk, and I kinda got a little depressed over it, so I ate the cake. Sorry about that, man.
-Dr. Evil Villain"

Turd Sandwich

and in that sandwich he would find a time machine that would only work if he ate the sandwich and then deposited the machine (its only 3.5mm) into his anal cavity

 

[The87Italians]

A holo gram of the princess/object that would continually move backwards the closer he got to it, like magnets with the same poles.

 

[FolkLikePanda]

A Bouncy Ball and Christmas Card.

 

[Sampler]

leekspin

 

[Lazy Kitty]

A big red X (a circular tile with a 1 meter radius) on the ground in the middle of the room and a big television screen which I'll use to tell him to go stand on the X.
Ten seconds after I told him the rest of the floor falls into a really deep pit with spikes on the bottom.

leekspin

Meatspin.

Oh, I am bad.

 

[Church256]

A note telling him who I killed and what I've taken over while he's been pissing about with all my perfectly made traps and tests...


oh and maybe a peice of cake to reward him for being so gullable to have followed my obvious distraction plan.

 

[TheGreatCoolEnergy]

I would leave him a leaf blower.

 

[CaptainREBell]

The 'Punked' TV crew.

Ha! It made me think of this http://www.youtube.com/watch?v=Z7sE0qMvltc

Eight rupees? Damn! I´m not that cruel.

 

[ucciolord1]

Nothing.
Nothing but an unmarked room with no air vents, and one giant 24-foot-thick diamondillium door. That closes as soon as he enters.

 

[Bohner239]

Kanye West. "Ya know, I'm happy that you made it this far, I really am, but LINK WAS THE BEST HERO OF ALL TIME"

 

[benylor]

A waxwork model of the princess facing away from the entrance. Due to the low lighting, it'll appear to be real until the hero circles around to "her" front, only to find the face is replaced with a speaker.

Which then proceeds to rickroll, naturally.

Then my most powerful lieutenant will enter the room and engages the protagonist in a challenging mini-boss fight - the leader of my Quirky Mini-boss Squad. His quirk will be mindfuckery - as it turns out, the entire base was a trap and the enemies the hero fought were robots. But now the lieutenant's real squad is all over the place and the only way to exit is to kill the lieutenant. Shifting walls/corridors, robot "corpses" rising up to take a pot shot at the hero every now and then, traps, holographic images of the princess that the lieutenant uses as a human shield, and, of course, once the lieutenant goes down for the first time...

As the hero leaves, he crawls out. And radios ahead. More Xanatos gambit-ry ahead.

 

[Twilight_guy]

A very nice letter written on fancy stationary.
"Dear Hero,
I appreciate your effort in attempting to foil to my plot. I applaud your overcoming and preserving despite the many hardships that the road and my evil minions have set before you. I respect your determination and unfaltering selfless dedication to helping the world. Unfortunately, I'm afraid that your Mcguffin is not here. Unlike most villains who leave such things just lieing around for a hero to find, I have put your Mcguffin into a cannon and shot it into the sun. The world is doomed. It makes me sad that all of your effort is wasted despite your efforts, but please accept this parting gift.
Signed, The evil dude."
The building would then be instantly blown up (no countdown, no warning).

 

[bluepilot]

The head of the friend/family member who died

Okay, so my style is a little macabre

 

[Rhayn]

Knowing me, I'd probably forget to pack the powerful artifact the hero was after when I switched to my overly intricate space station of doom, thus, in the final battle, the cutscene would go...

Me: So, we meet again.

Hero: Yes...

Me: So what do you think of my creation? It's quite magnificent, is it not?

Hero: Maybe, but your plans end now, villain. I have come to stop you.

Me: Ah, you fool! You might have bested me last time, but this time I have the advantage of fighting on my own ground. *Pulls out sword of evil*

Me: There is nothing you can do. This is the sword that slew your mother. Her very soul is embedded in this blade.

Hero: Ah, but you forget... *Pulls out legendary artifact*

Me: Shit, I knew I forgot something.

Hero kills me, space station gets blown up, mother's soul is released from sword and the earth is saved. Curse you, memory!

 

[Hookman]

A android copy of the princess they've been searching for,programmed to knee the hero in the balls everytime he stands in range of her. If the hero is dumb enough he will live the rest of his life with her,thinking she is the real princess just very,very angry.

 

[NotAPie]

A note saying "I'm sorry, I took your sword, but I left this nice paper for you!"
Or
A big door that makes up most of the wall in front of him...only its locked and the key for the door is in a pile of needles.
