Color Me Sad, you get Sheep the Mareep. Indeed, he must live up to its expectations, right? Soooo, that means it can only do things sheep can do too. You might have guessed it, but that means no usage of electric moves nor other moves not seem fit on a sheep, as I've never seen a sheep electrify someone or do any other ramdon crap now, have I. Therefore, it can only use moves which seem to be possible on a normal sheep. For any questions, do not hesitate to ask me. Well then, Mareep is a little bugger, it sometimes paralyzes people. Normal sheep cannot do this, so it can evolve into ampharos (yes, ampharos) after paralyzing 25 trainer owned pokemon. However, paralyzing someone is not nice. Pay the medical treatment of 5000 pokedollar per paralyzed pokemon by throwing away said worth of items. As an Ampharos, it learns it is special and not at all a normal sheep, so it can use non-sheep attacks, but only a maximum of two of them, as it still thinks about the old times. Solo an elite four member to prove its strength.

Incolea, take Totem the Natu. Totem is a stationary pokemon, it hates moving (thus also flying). It can therefore only use moves it does not have to (physically) move for. Any moves in doubt, just ask. After soloing any gym, it can evolve into Xatu. As a Xatu, it realizes how stupid it is, what it is doing. It can now learn any move it wants, but it should always use the weakest move (after stab, weaknesses, etc.) on the opponent (no using immune moves though, I am not that cruel), because it wants to make up for having been so stupid. Solo an elite four member to complete its sinning.

Garchomp612, take Doomed the Geodude. This Geodude has escaped from hell only to repent his sins. When it still was a happy geodude, it once pulled a diglett out of the ground, which is a deadly sin, so he was sent to hell. Due to good behaviour, he has been given the opportunity to show he can be a good boy (girl) again. First and formost, the powers of hell have restricted him to his current state. Poor Doomed cannot evolve, as he has to face life again as he once was. He has to repent his sins by punishing himself, therefore (ASAP), he can only use moves that also damage him (including self-destruct, double-edge later on). After having damaged himself a total of 20 times against trainers, hell gives him the knowledge that the self-inflicted punishment has been enough. He has to prove his worth by soloing a gym leader of a primary type he is weak to, with any level-up moves he learns (no using tm's). When he achieves this, he is soooo happy and hell tells him his punishment is almost over. He has to go see the diglett he once harassed. He finds out the diglett has evolved into a dugtrio and was catched by a trainer --> fight any trainer owned dugtrio. Survive 5 turns against it without killing it or fainting yourself (no healing), in order to talk to the dugtrio and ask forgiveness for your sins. After the 5 turns, ko the dugtrio with another pokemon. Doomed has been completely forgiven by hell and any current restrictions are lifted. Instead, he has to solo the last pokemon of every elite four member (including the champion) and knock their pokemon out with explosion (or self-destruct), because he likes to commit suicide, especially more than once. By doing so, he reminds himself of hell and his terrible time there. Fainting reminds him to never sin again and go back to that terrible place. Winning of the arguably strongest trainers of the region makes him believe he can still be succesful in life. (Oh, if there are no trainer-owned Dugtrio, change that to a wild dugtrio. Only then though)
