Kryptonite Is Everywhere/Playing With

Basic Trope: Every opponent a hero faces has an immunity to their power.
 * Straight: Amazing Girl can breathe fire. However, every enemy she faces either wears fireproof armor or finds another way around it.
 * Exaggerated: Amazing Girl is a Reality Warper who can stop time. You'd think this would make her invincible, but all of her enemies have some countermeasure.
 * Justified: Amazing Girl's powers are well-known enough to where her enemies are able to prepare in advance.
 * Amazing Girl is weak to something fairly commonplace, such as metal or plastic.
 * Inverted: Amazing Girl's powers are pretty useless, but coincidences come up to where she wins the day anyway.
 * Alternatively, Amazing Girl's powers are feuled by Tropanium... which all of her enemies have for some reason or another.
 * Subverted: Emperor Evulz boasts that he has a fireproof cloak and that Amazing Girl is useless before him. She merely busts out a different power and kicks his ass.
 * Double Subverted: ...Those two powers are literally all she had.
 * Parodied: Amazing Girl only uses the fire powers because she's contractually obligated to - she uses them once, sees they don't work, then goes straight to fisticuffs.
 * Oxygen nullifies Amazing Girl's fire powers, so she is practically powerless.
 * Deconstructed: The forces of evil are Genre Savvy enough to prepare countermeasures against her powers - and with those in place, Amazing Girl is injured - or worse, killed.
 * Reconstructed: After being injured, Amazing Girl finds different ways to utilize her powers, or starts training to use other powers entirely.
 * Zig Zagged: Amazing Girl's powers aren't always useful; partially due to bad luck, and partly because the most dangerous enemies are the ones who can find a way around her powers, so she has to often mix her powerful abilities with a bit of wit and brains.
 * Averted: Some opponents employ countermeasures; others don't.
 * Enforced: "Crap, I just realized that the power I gave Amazing Girl is a total Story Breaker Power! What do I do?" "...Well, you can write it to where all her enemies have a way around it." "...Genius!"
 * Lampshaded: "FIRE BREATH! ...No effect? This one, too?"
 * Invoked: Emperor Evulz, seeing that Amazing Girl is kicking his mooks' asses with her Fire Breath, starts assigning them fireproof armor.
 * Defied: "The fireproof armor trick was nice, but I came prepared too."
 * Discussed: "Why are my fire powers so useless all the time? Furthermore, why do I keep using them?"
 * Conversed: "I'd say take a shot every time Amazing Girl's powers run into a roadblock, but then we'd all go to the hospital."

Gack, Trope-o-nite! Your one weakness! Quick, run back to Kryptonite Is Everywhere!
