The alienaverse is a verse inhabited by aliens. (Technically, everyone outside Earth would be considered an alien, but the aliens in the alienaverse are actually aliens to the people of the infinitiverse even though they are actually in the Infinitiverse.) The alienaverse is filled in as you can see. Mr. Alien comes from here.
