Tumblr is easily one of the most important and widely-used blogging platforms ever invented.

Personal expression via the microblogging social platform has allowed users the world over to create, share, and comment on content that is as diverse as Tumblr itself.

And then there's Bad Sonic Fan Art.

The Tumblr brazenly defies expectation by accepting fan art of Sega's most famous mascot, Sonic the Hedgehog, from users around the globe. And the results are, um, wow.

The content runs from the melodramatic to the, ahem, erotic, but mostly exists in the realm of bizarre interpretations of the characters from the Sonic franchise.

It's confusing, uncomfortable, and way more sexual than we thought possible. Enjoy.
