Definiitely the villian that entire avi just breathes evil

Gah, Wings beat me to it, but this is my take on Minuxe:

It is dark, the moon is out, the setting is... well, a destroyed city. Is Minuxe responsible? She has the demon thing going on, so my first instinct is to say villain. But I've read so many stories wherein the demon is actually the hero, that I have to say, appearances are often deceiving. In this case, Minuxe is certainly the hero, a demon detective tracking some true evil using supernatural senses.

Wings:

This one is a hero, too. A keeper of the balance between hot and cold, darkness and light. She's very hopeful, too!

Seems evil, lol. I think it's because of the dark colors. And maybe the ears, they make the avatar seem mischievous along with the black flowing cape. xD

Hero.

You look like you have magic.

I am gonna say villain. You may look cute and innocent but i think its all a disguise. You look ready to pounce on an unsuspecting person at any moment. That umbrella could even be a sword, and thats no balloon but some kind of flying device.

I'll have to say Villian. The yellows and reds and black automatically make me think some kind of chicken or rooster-obsessed villian that has mechanical chickens flying around and pooping out egg-bombs.
Yeah. I'm crazy like that. xD

Abomination looks like a hero, specifically a ninja hero. I guess the bright strong colors make me believe she is righteous.

Definitely seems like a villain to me because of the colors and evil looking wings.

With all that sparkle, you for sure have to be a villain hero! What else could you be? <3

I'm going to have to say a HERO. She looks very nice and pretty yet there is definitely a toughness to her so she'd probably kick your butt, but it'd be for the right reasons.

I'd say hero. Your eyes look too nice to be a villain. Of course, you're definitely one badass hero! >D

Happy sort of looks like a victim... with the toy gun and school child-esque outfit...! xD So cute~

victim. you look all innocent with your giant spork.... i think you'll get run over by accident.

Totally a villain. Screams mad scientist, or even frankenstein in the graveyard collecting human parts to build his creature. xD

I'd say a hero. You look like the type who'd show the villains whats what.

Villain. You look like Little Red Riding Hood..but..ya know...way more hardcore. You probably hunt the forest for wolves. Therefore, you're the villain and the wolves are trying to go see their sick grandmother's and running from you.

Seeing as your avatar reminds me of Scorpion from Mortal Kombat, I am going to have to say your avatar reminds me of an anti-hero. Not quite a hero, but definitely not a villain.

Hero

Ready to fight all sorts of evil with her wise owl by her side to help her make judgements on what to do. : D

tornado rangler! .... that would be a Hero... at least a hero of mine. so cool! :)

definitely a villain... I mean, I can only think of one scenario where it could be a hero, and it's a far-fetched scenario, besides, it's just got that creepy villain vibe going... ^ ^

Hero. Like a very cute and stylish hero that knows how to chase the bad guys away with her sparkle powers and bubbles. =D

Hero~ With the bright color contrast to the black, you would undoubtedly be a hero. It doesn't have the main hero feel to it though~ feels like a sidekick or a hero that has a trusty companion.

Edit:
You know Happystarr~ You had me dead on last time XD
So I'd like to take this moment to thank you ~*~<3~*~
