Reserving for SS and Spuds.
Spuds, take Skinny the Bellsprout. Now, Bellsprout is one of the skinniest pokemon around, but this one wants to change. He's going to get beefed up!
So first off, Skinny has to start small. Skinny must solo 10 pokemon from each of the following groups: Levels 2-3, 4-6, 7-10, 11-15, 16-20, 21-25, 26-30 in that order. (If you're soloing level 2-3s, and you find a Level 4 Pidgey and solo it, then it does not count, but if you solo it while going against 4-6s, then it does.) After Skinny has completed this, then it may evolve. Now, Skinny decides that all this grinding isn't enough- he has to get on the 'roids! Rename it Addict. Addict gets addicted (obviously) and must consume all of your Vitamins and Rare Candies that you find, and you must buy Vitamins for it to consume whenever you have enough money. Addict finds out about a good dealer, who gives out the premium stuff. But when he goes to meet said dealer... it was a trap! It was actually Koga, disguised as a dealer! Addict must solo Koga. After the battle, Koga convinces Addict to quit- he can get ripped some other way! You may now evolve Addict, and rename it Quitter. It tries to quit, but Quitter is finding it difficult. So, you may no longer buy Vitamins for Quitter, but it must still eat all the Vitamins and Rare Candies you find. However, whenever it does, it feels guilty, and you may not use Quitter for 1 hour of game time, and you must throw out items worth $4900 or more. At some point, you must run out of money because of this. When you do, Quitter decides to quit for good- all of its restrictions are lifted. It just has to get nice and buff some other way. How? By challenging the best! Quittier must solo Lorelei! Finally, your Victreebel has achieved its greatest dream- getting big guns. Rename it Ripped. Have fun!
Super Saiyan, take Smug the Weedle. Now Weedle and Caterpie have always had a big rivalry. Your Weedle is convinced that it is superior, since Beedrill are superior to Butterfree (in competitive battling at least). So, Smug must solo every Caterpie/Metapod/Butterfree that you encounter, including wild encounters- running away is not allowed under any circumstance. Smug must also do what Weedles do best- POISON HAX!!! So, Smug must keep Poison Sting forever, and whenever the opponent is not poisoned, Smug must spam Poison Sting until it is. Even if the opponent cannot be poisoned (i.e. is a Poison type or has another status) then it still has to spam Poison Sting, since Smug is pretty determined. Once Smug solos 10 trainers, it may evolve into Kakuna, and once it solos 15 more it may evolve into Beedrill. All restrictions carry over. Smug believes that it is not only better than all Caterpies, it is also better than every other pokemon in the world!! So, Smug must solo Giovanni in the Gym battle, and Lance's Dragonite. Enjoy!
