Dear Sir/Miss/Whatever you are,
Let's face it, you are probably the biggest waste of super powers anyone has ever seen. That's right, you're powers are pretty useless but fortunately for you, they make you an outcast among all the lucky normal people. You can't fight crime or help any real superheroes because like we all already know your powers have no real practical use and that is where we come in.
Sincerely, The USO (Useless Superhero Organization)

Backround: Founded by a man whose power was to throw up precious metals, the USO functions as a home for super heroes who have been deemed 'useless' by other heroes and the world in general. Thanks to the founder's painful yet lucrative efforts the USO is located on its own private island, complete with anything one could ask for. The USO also collects missions that can hopefully engage some of the supers on the island. 
Other: Each hero is given a sort of weekly allowance based on how useless their powers are, naturally people whose powers are more useless are seen as the 'cool kids'. The inhabitants are allowed to leave but are encouraged not to because the world can be quite harsh on them. 

Tell me what you guys think, I hope this does manage to get support.
