About This Quiz

Did you know there have been five different Ben 10 TV shows already? And four different movies? That's a lot of Ben 10. That's like Ben 90. Plus, don't forget about Ben 10,000. With all those series' and variations, Ben has graduated from just 10 aliens to all kinds of them. Some have evolved and changed from the original series into other ones, some vanished entirely, and new ones were introduced. Favorites like Humungusaur seem to have been around forever, while others like Pesky Dust have only had a brief time for audiences to get to know. However they've been introduced and handled, they've all been pretty memorable. And critically acclaimed, even. Ben 10 won three Emmy awards!

As the Cartoon network's longest-running franchise, Ben 10 has been in action since 2007, and that has spawned numerous toys and video games as well. Word is that the franchise is worth about $6 billion, which is amazing. So all of those aliens, from Ripjaws to Ghostfreak, Chromastone to Alien X, all have to be earning their keep. Think you know your way around an Ominitrix and all the DNA samples it holds inside? There's one way to find out! Take the quiz and see how many you can ID!
