Uh , Yes because I was thinking that it looks kid friendly enough to be in those type of series , So is that a good plan or No it can't ?
@danhimself: are you sure ? cause the reason I want a crossover is because Aang and Captain America both slept for a very long time and he might live in ChinaTown cause I read a pilot of Naruto and the Main Character himself lived in Japan unstead of the Ninja world , but I can see what you're saying .
I'm sorry, but this is a ridiculous question. Which I see this OP asking, a lot. Sharing a few similarities doesn't mean two universes can mix. And it isn't hard to try to find things alike in comics. Why? Because comics has a bit of everything. Avatar and Marvel don't mix.
Oddly enough, back when it was Marvel that did all the licensed comics and not IDW, Valiant, and Dark Horse, Marvel inserted pretty much all the licensed material into the mainstream marvel universe.
Godzilla fought the Avengers
Spiderman shared words with Optimus Prime
Reed Richards had the Doctor's phone number on speed dial.
And so on so forth.
Some, like Transformers, were discretely shifted into their own separate continuities when it became difficult to reconcile them with Marvel as a whole, and to be fair Marvel's transformers line was extremely long for a licensed marvel comic. But most went their entire run within 616.
So actually if Marvel did make an Avatar the Last Airbender comic, going by precedence it would likely be slotted into the mainstream Marvel universe.
Of course that practice kind of ended early in the Transformers' run in the mid eighties.
Could it? Yes, a universe is a big place. Should it? No, Avatar TLAS would be rather marginalized if forced to coexist with the Marvel universe and really gains nothing as a setting from it.
I agree with this.
