[Super Saiyan]

@yaya0, your starter Pokemon is Pulpip the Piplup. He has the Fire-Grass-Water chart backwards. If he faces any fire Pokemon, he must use Water Sport first and cannot use water attacks since he thinks they're not very effective. He must solo all grass Pokemon he is sent out against since he believes he has the advantage. ASAP, his moveset must be:
Water Sport
A damaging Water attack
A damaging Flying attack
A damaging Steel attack
He must solo Gardenia and Flint. He also must always solo Barry's Turtwig/Grotle/Torterra.
No restrictions on evolution except nickname Prinplup, Pulpnirp, and Empoleon, Noelopme.
Good luck!

@Tyranitarphantom, take Trunks the Eevee. He is from 3 years in the future, where Team Rocket has taken over the world. He wants to stop them at all costs. Buy a Thunderstone to evolve him into Jolteon ASAP. Now that he has powered up, he wants to solo every Team Rocket Pokemon that isn't a Ground type. He is very fast so must always know Quick Attack and/or Agility. Once Team Rocket has been defeated in Celadon City, he realizes he has saved the future and decides to keep travelling with you. In the Final battle with Giovanni, he cannot be used, due to his Ground-type weakness. To make up for it, he solos Lorelei. Good luck!
