I can easily breed a 5IV one within a half hour if I dedicate myself to that. Not counting the time to briefly train the one I then inbreed for the 5IV. I think I have 5IV Scyther, however!
Have you finished the game yet and become Champion? Until you do that, no one will get anything other than the Emolga or Stunfisk. The third is unlocked when you become Champion and then see people online as Champion, and they can then go see your third. So finish the game and you'll be able to find out who the third is! (As a note, it can only be Manectric, Luxio, Zebstrika, or Galvantula.) Also, people can get hidden abilities from your Safari once you see them after becoming Champion - and vice versa. :)
