Of course. The Skrulls are shapeshifters. That's probably in your files, right? They infiltrated pretty much everything they could, including a whole bunch of Avengers. Hank, Jess Drew, Sue Storm... They were all kidnapped and impersonated. No one had any idea who was actually themselves. It was a freaking mess like I've never seen.
Hank had been kidnapped when we were in London and having troubles. After the Avengers disassembled when Wanda... Anyway, I left him when I caught him with one of his graduate students. I was leaving anyway, but that just made me think it was the right thing to do. A few months later, he tried to give me a gift. New Pym particles that would help me grow big and then small and vice versa without having to recover basically.
Turns out he injected me with some biological weapon that when I went big would pretty much infect every living thing on the planet and kill them when I exploded. He used it when the Skrulls started losing. I didn't want to kill everyone so I sort of concentrated really hard on shrinking down as small as I could get.
