where as alot of the stuff your saying i doubt will happen, i believe that one CAN join the group at a certian time and that as you grow in power in their ranks you may become a lesser form of the girl in the " lots of baddies " vid. granted i doubt you will be summoning up armys. also i think you will be able to change your char alittle to fit in with the HLO. example :
