Get a bad egg that has Pokeruss - Pokemon Sapphire
Get a bad egg that has Pokeruss
Enter the master code:
Note:You must have master balls. If you let it get away, the game freezes.
Enter this code:
This code works about 25% of the time. Either the wild pokemon will not have any HP, or there will be a question mark like on the pokedex. If it's the question mark, catch it with the master ball. It will say the data has been added to the pokedex. Nickname it ???.
Then look at your pokemon and there will be a bad egg. Look at its summary. It will say it was obtained at the daycare. It will say that it will take a long time to hatch. Try to get it to hatch as quickly as possible by taking a lot of steps. If you let it hatch really late, it will be a pokemon that you can easily catch, like a zigzagoon or a poochyena. If you make it hatch early, it will be a mystery pokemon. A mystery Pokemon could be anything like a Jirachi, a Raquaza, one of the regis, a Bulbasaur, or a Mewtwo. Unless you get Mewtwo, it won't completely screw up your game. If you get Mewtwo, turn off the game and leave the egg in the pc. The egg usually (but not always) hatches. So stock up on the bad eggs!
