Downplayed: Amazing Girl is able to breath fire. Most common fire safety devices are easily employed to keep the damage she might cause from spreading, but there isn't much opponents can do to stop her breathing fire on them directly.
Amazing Girl's powers are well-known enough to where her enemies are able to prepare in advance.
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.
Writer 1: "Crap, I just realized that the power I gave Amazing Girl is a total Story-Breaker Power! What do I do?" Writer 2: "...Well, you can write it to where all her enemies have a way around it". Writer 1: "...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".
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.
