Within the RC Universe, a great many super heroes operate without being formally attached to any particular organisation or team. Either they are not inclined to work with a team, they belonged to a team which has since disbanded, or else they live in areas where law-abiding parahumans are rare. As it happens, many of them are generally associated with teams that they have frequently worked with. Each has their own reasons for remaining a solo operative, though, and so they remain independant.
