Strength changes

[Kai]

One category that doesn't get much discussion here is changes in strength. Muscle-enhancement is pretty widespread.

It's also possible to just increase someone's strength without any visible external change (as long as you don't touch them or something, then their muscles would feel like steel!) This might seem like it wouldn't have a process, but it could... someone slowly rising in strength, going from ordinary to wonder-woman over the course of a story, learning to control their newfound strength, etc. Could be interesting.

Loss of strength is less common, but can be interesting, too...
