Corrupt a Superpower

This is pretty much the same as the "corrupt a wish" game, but instead of wishes, you say what superpower you would want! then the next person corrupts it in some way, and says a power they'd want, and it continues.
Example:
Person 1: I wish I could fly!
Person 2: You can now fly! but only because you're a bug. I wish...
etc.

I'll start us off with: I wish I could shapeshift!
