Then retry the method again to beat the next trainer. You can also use the trick fighting your rival or other type of trainers.
Pikachu Surfin Trick
You have to capture a male Smeargle, and a female Pikachu. Make sure the only attack Smeargle knows is Sketch, preferably more than one. Breed them together and you'll have a Pichu that hopefully knows Sketch. Evolve it into Pikachu and then battle a friend using the Pikachu in your line-up. Make sure your friend has a Pokemon that knows Surf. Battle the Pikachu and the Pokemon with Surf. Now have your friend to use Surf on Pikachu. Make sure Pikachu's strong enough not to faint. Then use Sketch and you will now own a Surfin Pikachu. If you want, you can trade it to someone's Pokemon Yellow and then play the Surfin Pikachu Game at Fuschia. Please Note this trick may take a few times before you get the Surfin Pikachu.

The only other way is to have a GB Gameshark and finding the code there is no way to duplicate this one.

Fuchsia City Gym Fighting Tips
Once you reach to Fuchsia city gym you will see lots of ningas. Only one of them is the gym leader, and the others are fakes. To find out, talk to each one. If it is the gym leader, it will stay in the ninga suit. If not, it will show its real person and battle you. She carries five Pokemon and each is levels 28 to 30. Flying attacks will do the best because her Pokemon can kill themself and try to hit you. If you are in the air it has no effect and the pokemon simply faints. Once the pokemon is down and defenseless the rest is easy and quick.
