It started as a group of ordinary terrorists who thought that regular people were a disgrace to all of ordinarykind. The group gained popularity until over half the population of everywhere was against regular people. Outnumbered, the leaders of the United Verses could only join them if they hadn't already, causing the official start of the Regular Extermination Project. They invaded and searched the entire Infinitiverse for traces of regular people, and eventually there was nowhere else to go and nowhere to hide (so they say).
Due to inaccuracies and mishaps many regular people are said to have survived extermination, but no one who dares speak in public says anything about the situation.
