Needs More Examples
As noted on Personality Powers
, giving a character a personality which fits with their abilities (or one opposite) is good shorthand. However this trope covers cases where having a personality which matches the power (or developing one) is risky and avoided. This risk might be because;
Compare The Dark Side
(when using the powers actively corrupts you and shifts your personality), The Corruption
(for powers that come from being corrupted) and Bad Powers, Good People
. Contrast Bad Powers, Bad People
. The need for restraint this trope implies might make the power or skill in question a case of Blessed with Suck
or Cursed with Awesome
- In Avatar: The Last Airbender , Firebenders are (mostly) calm and collected to avoid losing control. Jeong Jeong (who explains this) in particular considers firebending a form of Blessed with Suck. Aang demonstrates this when he tries firebending and ends up losing control of the flames he creates. Benders of other elements avert this by working most efficiently when they have the expected Personality Power.
- Mace Windu in Star Wars: Revenge of the Sith has a very aggressive homebrewed lightsaber dueling technique called Vapaad which skirts very close to The Dark Side. He needs to have a great deal of discipline and concentration to avoid succumbing to it (as opposed to the aggression you would expect a user of such a style to have).
- In Buffy the Vampire Slayer it's implied that Slayers tend to develop boodthirsty personalities from all the fighting they're expected to do. Faith serves as an example of why this can be a bad thing.
- Some continuities of The Incredible Hulk imply that despite his Super Strength powers (which are powered by his rage), the Hulk also makes use of Banner's intelligence on some level to use his strength more efficiently (indeed, many early comics, where the Hulk was a sociopath rather than stupid, had characters comment on how quickly and quietly he was able to move despite his size). As opposed to being The Berserker as you'd expect.
