Freaky Friday (Avengers version)

What happens when the alien matter left over from multiple Avengers battles is collected?
What happens when it is moulded to create weapon?
Something made specifically to defeat the Avengers?
What happens when supervillains get their hands on this weapon?
A weapon that will that mess up their lives?
In other words, what happens when the Avengers swap bodies?

I'm really sorry this story will be discontinued
