@Ray Jay; Man, that took some serious effort, man. Well, Courage the Cowardly Growlithe is a little more keeping to the cartoon...
- Still has to run from anything at a higher level than itself, still has to use 65 BP moves after STAB, cannot evolve until it has proven itself (see previous method of evolution), against a gym leader. Stone may be used afterwards.
- The solo is shifted from Bertha to Bruno, and your attack-pool is no longer limited to Recoil moves; any physical contact move will do.
Note: Remember, the solo is not a requirement; it just saves you from Incurable Cowardice.
@Sharpedo; well, I'm not too familiar with Emerald, but it can't be too different from Ruby, right?
Anyway, take a Taillow, name it Banshee if female, or Fluffykins if male. Banshee believes, beyond the shadow of a doubt, that she is simply the best Flying-type. And I won't disagree; she is pretty awesome. But none of her other friends believe her, because of her small size and low Stamina. Haters gonna hate, but she's not about to let these OU fangirls tell her where she belongs.
-Banshee must overcome every obstacle that she faces; if ever sent out against an opponent, a pokemon must faint, whether it be them or her.
-For some reason, her most powerful attacks are limited; everytime she a move with 85+ BP after STAB, she must rest 2 turns before using another (Example; Return, Quick Attack, Double Team, then Aerial Ace).
-May not use Facade; Facade is for fakers, and Banshee keeps it real as much as she can.
-A certain Flying-gym leader resides in this land; Solo her on your first try, Banshee may evolve. Should you fail, an alternative would be to solo the God of the Skies...
Optional: If Banshee solos both Leader and God, it's move limit is lifted (The second dash).
