>>14278099Hell yeah, imagine some pseudo legendary massive worm type Pokemon akin to the sand worms from Dune. Not sure how you could explain it being on Pokemon earth but maybe it could be like the thresher maw from Mass Effect? Its eggs can survive the vacuum of space and are extremely durable, so they cling on to space debri and stuff.
Maybe you get a "Strange Egg" item that hatches into it or there's a side quest type thing where you explore a cave that a fully matured one has made it into its home. The possibilities are endless and thrilling.
