This Ben 10 trivia quiz has 100 free questions with answers and covers the whole franchise, not just the summer road trip. It starts with the original 2005 series - Ben, Gwen and Grandpa Max in the RV, the ten starting aliens, Vilgax, Kevin 11 and the Plumbers - then works through Alien Force, Ultimate Alien, Omniverse and the 2016 reboot, plus the two live-action films, the animated movies and the video games. Roughly a third of the questions are easy warm-ups written for younger fans (which alien is made of fire, what Ben shouts before he transforms, what Grandpa Max's RV is called). The rest climb through voice actors, working titles, episode trivia and merchandise numbers to the kind of detail only someone who watched all 393 episodes would know. Every answer has been checked against Wikipedia and the sources it cites, and each explanation adds one more thing worth knowing.
