Thinking about it, if all the avengers got hit that would leave only Iron Man and the Hulk as functioning adult superheroes. All the rest of the avengers got their powers as kids. Cue Tony Stark and Bruce Banner trying to take care of a whole bunch of superpowered kids (including baby Thor because he was born with his powers). I think Matt would actually be one of the older ones, and therefore would have to help supervise the little ones.
