Pyrokinesis. Translation: Saves $.22 cents a year on matches.
Why It Sucks:
As Claire Bennett's biological mother, Meredith Gordon has a unique power shared only by anyone who's ever spontaneously combusted and Johnny Storm from the Fantastic Four. She can create fire with her bare hands. That's one better than Pyro from the X-Men, who can only "manipulate" the fire but can't create it. With a power like that, Meredith Gordon could, dare we say, take over the world. But instead she primarily uses it to light her smokes and her propane stove, which is precisely what most people would do with it.
Sure, you'd go through at least a few boxes of plastic utensils for the first several weeks as you melt fork after fork, but after that, then what? If you really think about it, how often do you actually need to make a fire? If you're a hippie and you light candles, incense and campfires and burn your bra a lot, then sure, we'll give you that. But most normal people, especially the non-smokers of the planet, will call on this power two to three times a year, and even then, mostly to just dispose of old boxes from storage or piles of leaves in the yard.
Of course, you could use it for evil, but you need only turn to modern gun statistics to find that less than 1 percent of gun owners use it on another human being. Why would having fire hands be any different? At best, you'll be able to realistically portray the Wicked Witch of the West in your school's production of The Wizard of Oz when she says, "How about a little fire, scarecrow?" Everyone will ooh and ahh, except for the actor portraying the scarecrow, who will unfortunately be incinerated alive.
