Groupthink: New character aug/mutation ideas

Hey all, me again. You know that other Groupthink thread about Gear ideas? Had a few write-ins for things that weren't really Gear related, but for stellar concepts nonetheless. I figure it's time to branch out a little.

So this is like that thread, but for augs and mutations. What new aug would you make, for what character, and why?

Ready? Go.
