When fairy tale good guys are portrayed negatively

[Lost Soul]

For Shrek 3, my guess for Red Riding Hood being a villain is because the Wolf is a good guy. Charming being a villain is because Shrek screwed up his plans for a "happily ever after" as in marrying Fiona and ruling Far Far Away.

Futurama - Santa Claus (though created by mortals) is an evil robot that thinks EVERYBODY (save Zoidburg) is naughty. People hide in their houses every Christmas Eve if they want to escape his wrath. His elves are seen as the "bad/poor side of town" sort of folk.

I seem to remember a Bugs Bunny short in which the Easter Bunny manipulates Bugs into doing his job, too. It wasn't in a positive light but I don't know whether to call it negative.

While not strictly a fairy tale it's fairly close:
Grendel Grendel Grendel based on Grendel by John Gardner.

Oh and Ed Liu; sorry I can't find any news on an official DVD release to cash in on the new Beowulf movie coming out.

In a Animaniacs segment featuing the Hippos, Noah from Noah's Ark was portrayed as a young, lazy careless bum.

The Fairly Odd Parents had Merlin the magacian protrayed as a minipulator pupet master.

Yes that's a stretch; I mean it's not like in the original story he was a guy that facilitated a rape to serve his own ends or anything.

it's not so much fairy tale good guys are shown negatively it" that it's uselly the reverse for the bad guys the big bad wolf is a hero (hoodwink) the wicked witch is misunderstood and the giant from jack and the beanstock is a victem

Well, this is also a bit of a stretch, but there are Popeye cartoons where Bluto portrays Sindbad and Robinson Crusoe.

Robin Hood came off as pretty vain and dumb in Shrek.
