I didn't add all movies;only those with more "darkness" in..

Pixar violance... XD Darkes Pixar movie I EVER seen! I like it! XD

The villain in this one was actually very disturbing. Not only that it dealt with some serious issues like the long term effects of losing a loved one.

Ehehe..Carsfan,my immy... XDD
You're right,fanfly.. It's disturbing and astonishing to see a popular hero,someone who travelled around the world discovering lost treasures and unknown zones of the planet..in his real behaviour,a dark one,ruthless and deeply selfish.

Up and Toy Story 3! Muntz and Lotso were really dark villians. I know that all villians are mad but man!-Lotso and Muntz really showed us how mentally disturbing they are!!

Considering the fact that Syndrome had no problem KILLING Mr. Incredible's wife and children, I'd say The Incredibles was pretty dark. That part was really the only "dark" part in it though...
My second pick would be Toy Story, simply because when I was little, Sid scared the CRAP out of me!

Because it's one of the rare PIXAR movies with blood in it.

The climax in TS3 is very dark....

I cried at the beginning of this.

The darkest and the finest Pixar movie!

he is right for race

Everybody fat, rely on robots and technology

The incredibles wins for me as the darkest Pixar movie simply because of the fact that Syndrome had forced Bob to listen to his family 'die' then went on to mock the devastating and grieving father and husband
