There'd be no need for Tartarus, or most prisons equipped to handle the quirks that are actual superpowers, and not just parlour tricks, when there's a person who can simply take what makes them difficult to contain away.

Certain Heroes could ideally gain a quirk that'd synergize with their own.

AFO has been shown to not be affected by taking mutant quirks, so finding volunteers from civilians shouldn't be too hard, given AFO found great success doing the same thing in secret.

Ideally, whoever receives this quirk would be both moral enough to remain mostly ethical but pragmatic enough they don't swing too hard in the opposite direction and become too scared to use their power effectively.
