Two of my favorite superheroes are Black Panther and Superman.
In the movie Black Panther, when the Black Panther is in a coma, vibranium is used to stimulate him.
In the Superman movies, kryptonite is used to weaken Superman.
Thus, while vibranium has the power to enliven, kryptonite has the power to weaken.
You have the option to use your words as vibranium to make somebody stronger. Or you can use your words as kryptonite to make somebody weaker.
You can use your words to build people up or break people down. You can use your words to put things back together or tear things apart.
How are you using your power?
