The monster is only in the first one... SC2k replaces it with a alien flying saucer invasion... I think SC3k has the saucer too. I don't really know what the disasters in 4 are though... but about 3k I remember being dissapointed to seeing the flood and air crash being removed (and not replaced with anything) from 2k's disaster list.
