I believe you left out a few groups. An important one being the X-Men. Mutants with super human powers lurk and roam the earth unknowingly today and form secret groups in which they battle against each other. Some of you may have seen them before but may have not recognized them. An example of where I've seen mutants before in a community is at the local Occupational Development Center (ODC)...they may just pick up garbage and crush boxes, but at night is when they come out and cause havoc with their inhuman powers.
