Get Nintendo characters as Pokemon
First, you need a Pokemon who has the ability to Surf, one who knows Cut, and one who knows Teleport. You also need two Poke Balls.
Beat the game, but dont go on the S.S. Anne until you complete the game, then head back and go on the S.S. Anne. When you get on the S.S. Anne, heal the captain but dont beat every trainer on the ship. Leave ten of the trainers unbeaten. Then get off the ship, and as soon as you get off, before the ship leaves, pause and teleport back to the Poke center. Then stock up on potions and head back to the S.S. Anne. Youll find that the ship is still there. Get back on the ship and beat the remaining ten trainers. Then get off again.
Youll find that youre at a dock near a grassy area.Head north and walk until you get to an area with a green tree and two blue trees blocking off three entrances. Use Cut to chop the green tree down, and keep on going until you reach a town.
Now youre at Mushroom Kingdom. Head to the store and buy some Max Potions. If you have six Pokemon in your party, head to the PokeCenter, go to the PC, and put one of your PokeMon into the PC so that you only have five PokeMon. Then head to the gym, go inside, and beat Mario, the lone trainer in the gym. Hes really tough, but its possible. When you beat him, he'll give you the ability to jump(you press B to jump) and then he'll disappear. Then youll find that Mario is part of your party.
After you beat Mario, head to the PokeCenter, go to the PC, and put the PokeMon who can teleport and the one who knows Cut into one of the PCs Pokemon boxes. Then head back to the place where the blue trees were and hop over the tree on your right and continue walking until you get to a beach. When you get to the shore, surf to your right until you reach an island. The island will have a small forest and a lone rock on it. Get right next to the rock and press A while facing it. Donkey Kong will appear to fight you. Beat him and he will become part of your party.
Now surf back to the place with the blue trees and hop over the tree on the left. Keep on walking to your left until you reach a town. Now youre in Hyrule. Head to the gym and beat Link there. When you beat Link, he'll disappear. Now Link is part of your PokeMon party.
After you beat Link, head to the area with the blue trees and head back south to the dock. When you get to the dock, surf to your right until you get to an island and a shipwreck. Head to the PokeCenter on the island, go to the PC, and put the PokeMon who knows how to surf in a PokeMon box. After that, head to the shipwreck, and youll find a guy who will challenge you to a battle. The guy is Fusajiro Yamauchi, who invented Nintendo. Hes easy to beat and easier to catch. Use a Poke Ball to catch him.
Now, head back to the PokeCenter and add the PokeMon who can surf to your party. Now, head to the shore and surf so that youre right next to the top of the shipwreck. Now surf from one end of the shipwreck to the other, and eventually, youll face missingno. Catch him and save your game.
Now, start a new game and check what PokeMon you have. Youll now have Mario, Donkey Kong, Fox, Link, Mr. Game & Watch, and Bowser.
