People who ride folding bikes . <| sep |> I would assume a Pokemon is defined due to the name of them . Pocket Monster . So a Pokemon is a monster , something considered unnatural to us as real people . but how do they fit in out pocket ? Well that ' s where the balls come into it . I would assume that if something can be put into a pokeball then its considered a Pokemon . to a certain extent . Thats where scientists come into it . developing new pokeballs . meaning creatures like the ultrabeasts not being considered Pokemon will be as a new pokeball was developed to contain them and allow you to put them in your pocket . EDIT I think you are thinking to hard about this . EDIT 2 What if scientists developed a ball capable of containing a human ? ! would we become pokemon ?
