Over the past weekend, the latest Godzilla flick made its debut in American theaters. The film, which stars Bryan Cranston (Breaking Bad), Aaron Taylor-Johnson (Kick-Ass), and Elizabeth Olsen ( Captain America: The Winter Soldier) made its entrance with a bang. The film took the top spot in its opening weekend, netting over $100 million in ticket sales by May 19.

It’s only natural, then, that fans would begin pouring their hearts out over the city-destroying reptile. Of course, in this day and age, we live in a world where Attack on Titan exists. And, as one would expect, the two world have begun to clash in the imaginations of fans worldwide.

As far back as October 2013, we began to see the theoretical “what-ifs” appear on YouTube. Detailed run-downs, such as the one below by “The Multi-Battle Dome”, began to pop up, as fans pitted the mighty Colossal titan against the King of the Monsters himself.

As the film’s release date drew nearer, we began to see mash-ups of the Godzilla trailer and Attack on Titan footage begin to surface. The two titles seemed like a perfect fit: Attack on Titan saw humanity living in fear of the mighty Titans, just as they fled from the great Godzilla.

Naturally, this has also extended to the realm of fan-art. In addition to the mash-ups and the silly videos, we’ve begun to see various pieces of cross-over art start to filter into the popular haunts. Artists on Pixiv, DeviantArt, and even tumblr are beginning to post their own take on the theoretical match-up, be it in paints, digital art, or even action figures.

To see these two fandoms collide in such a grand fashion is something that’s incredibly offbeat, but undoubtedly amusing, for some reason. We’ve posted a few of our favorite images below. Let us know your favorite!
