10 Utterly Ridiculous Comic Book Weaknesses
4. Any Raw, Unprocessed Natural Material (Power Girl)
In her own words, Power Girl is weak to "any raw, unprocessed natural material", which means that trees, rocks, soil, ores and anything else that is produced by the Earth can harm her - and you have to agree that's actually a pretty horrendous deal.
Just being on Earth should be detrimental to her, let alone having to duke it out with super-powered bad guys in that very environment. One would assume that this has changed with two successive reboots DC have enacted since 2011, otherwise Power Girl is skating on thin ice whenever she suits up for danger.
