>>117297124Well, yeah. But a crossover story pressuposes that the shows can exist in the same universe without breaking suspension of disbelief. You can put Ben, Kim, Jake and Danny in the same universe with only a small amount of handwaving.
>Kim fighting the aliens in her finale can be just before knowledge of aliens becomes common in the Ben 10 sequel series. The original Ben 10, if I remember right aliens where still secret or passed of as villains. Or you can just ignore KPs finale.>Danny's stuff is mostly focused on his town. No reason why Kim or Ben would know about him. As the Am Drag Jake would be aware about Amytiville but be "As long as the rest of the world ignores Amytville the dragon council has decided to not mess with it. Like that high school with ninjas. Don't evven ask" Danny would be about as famous as Kim and Ben after his finale. Or again you could just ignore the finale.>Ben has very little contact with the magic world. Kim too. Jake is well aware of who and what Ron is but him being around supervillains and mutants actually helps keep the veil.Jenny is harder since she is supposed to be from the future.
But Rex's backstory is too world changing to work with other crossovers without using multiverse. Same thing with Steven Universe.
