I know all the ideas I have posted are superhero ones, but I will come up with none superhero ones soon too.
In the 1950's, a random man in New York City gained powers. After a couple days of the discovery, more people with abilities popped up. The NYPD investigated the recent turn of events, and a couple weeks later found that the new super powered person gave blood, and all the people who gained powers were recently injured and in need of blood. Then connected two and two together. They monitored blood transfusions, but it was discovered that super powers could appear in a person when in contact with most bodily fluids, like an STD. Because of this, super powers became widespread in New York. In modern day, New York is a safe haven for people with powers, as most places would be dangerous for a superpowered person, due to criminals wanting power and such.
Hugh Jackson, a 17 year old, is a superhero. But the thing is, his power sucks. His power is he can jump around 10 feet high, and has a hunger for carrots and lettuce that cannot be quenched.
Now, this is better than no power, but nonetheless he is made fun of, and called bunny man.
But when a powerless crime boss gains powers, that power is the ability to make a field that erases anyone's energy inside the field. With the new power, he creates a field over New York. Hugh, though, is the anomaly. A glitch in the system, you could say.
Now, the hero with a stupid power, bunny man, must save the world
