Your paranormal beings for today are the Harbinger and the Hybrid. The hybrid can be many things. Generally, it is two beings or creatures genetically combined to create a whole new being. The harbinger is a creature or being that can signal events to come. Harbingers can be seen as beings who pop in every once in a while and mysteriously show a glimpse of the future in a metaphorical way, or sometimes a literal way.
