The children of the Avengers have to... umm, avenge their parents, in a new direct-to-DVD animated movie from Marvel Studios. Next Avengers: Heroes of Tomorrow takes place after the Avengers have all settled down and gotten married (including Captain America marrying the Black Widow) and had tons of kids. Then Ultron, the crazy killer robot, comes back and wipes the retired superheroes out. The world's only hope: the Avengers' plucky kids, whom the heroes sent into hiding when Ultron's smackdown went into effect. I'm a sucker for next-gen stories like Batman Beyond, so I'm cautiously intrigued despite the cheesy trailer. [SuperheroFlix]
