Okay SS, I'll give you one. Reserving a spot now. I'll edit in later.
EDIT: SS, take Agony the Mankey. Agony loves pain, and such hasn't learned the true nature of pain yet. Agony must faint 7 times in trainer battles, and cannot use any STAB move until that is complete. Before that, Agony wants to show the rest of Route 3 some pain, and must solo the second half of route 3 (grinding first is OK). After you get 3 gym badges, Agony can evolve.
As a Primape, rename Agony Crusher. Crusher has learned the true nature of pain, and wants to CRUSH IT!!! So, anytime one of your other members gets into red health against any non-ghost type, Crusher must come in and finish off the pokemon. Also, Chrusher hates TM's/ HM's, and can never learn one of those moves. He must also solo Blaine, because his name rhymes with pain, and either Bruno or Agatha. Finally, Crusher must know and keep Focus Energy to help him Focus. (sorry if Focus Energy doesn't work in Gen 1).
