Marvel Studios has released the trailer for their newest direct-to-DVD animated feature, Next Avengers: Heroes of Tomorrow, and thanks to Marvelous News, you can see the trailer for it now.
From what we can see in the trailer, it seems that in the future, the various members of the Avengers have settled down and had kids of their own, just in time for the villainous robot Ultron to return. Ultron defeats the Avengers, and their children are raised elsewhere in safety. Now teenagers, the next generation of heroes has banded together to stop the robotic menace who defeated their parents.
Although it draws its name with the What If?-based title A-Next, it seems like Next Avengers: Heroes of Tomorrow, doesn't share any characters or storylines with the comic.
