Just as THAMF is a group of normals hating mutants, then R/Evolution is the other side of the coin:  a group of mutants who hate normals.

R/Evolution is determined to remake the world in the image of Homo Sapiens Superior.  They attract more angry and disgruntled powered people to their banner every day.

They provide a support group and sense of belonging and family to mutants who otherwise are unable to find peace in the world.
