And while it would be rational to believe that humanity's salvation may be delivered by a marquee Avenger like Captain America, Iron Man or Thor, there's one pint-size, second-tier hero getting big-time attention online: Ant-Man.

Where is Thanos-a seemingly unbeatable foe who can disintegrate half of all life in the universe-most vulnerable? His big, purple butthole, of course!

A fan theory that originated on Reddit posits that Ant-Man, with his ability to shrink down to be teeny-tiny, could easily slip into Thanos' rectum and defeat the Mad Titan from the inside. That Thanos could meet his (rear) end thanks to some sneaky butt maneuvering has taken on a life of its own, with over 37,000 fans signing a Brazilian petition that simply asks Marvel to let Ant-Man crawl up into the intergalactic despot's purple ass.

The biggest blessing (or curse) that "Thanus" wish fulfillment has wrought upon the internet has been memes on memes, and we've mercifully rounded up the best for you so your browser history isn't littered with iterations of "Thanos ass."
