Alright, I've got one here. Take Captain the Wingull. Captain wants to lead your team though the open seas, and so he must be the first one you catch and must always lead your team when surfing. Captain also fancies himself with the ladies; as such, he must always switch in on a female Wingull or Pelliper, use Atrract once you get it. He may not hurt a female Wingull/Pellipper, and may not run away or switch out (rejecting his advances) or you catch it (This takes precedence; If he is hit by a Wild female Wingull/Pelipper you may still catch it). To evolve, he must produce eggs with all your female Wingulls/Pelippers (ones you get in your other challanges). Good Luck!
