I need help! How do you beat Koga?

I would advise you level all of your Pokemon up. Also buy lots of antidotes. You'll see why you need them when you face Koga.

Get a Dugtrio, and get it to learn any Ground attacks possible, and keep the old ones it may have, like Magnitude. Get an Abra, evolve it to Kadabra, and level it up to 25 or 30, along with Dugtrio. Remember, Psychic and Ground are both effective against Poison types.

To the last guy who asked how I got a Mew: I did the Mew trick. It should be near the top of this page, or check the hints section.

Sfekt, I noticed in your submission you wondered how he got Mew; although you should place that in the Questions colomn, I will here answer it for you:

The six ways to get Mew...

1. First, find a Trainer, any Trainer at all, and battle him/her.

After defeating that Trainer, find a Pokemon of yours that has a Special stat of 21 or 277. Now, put it first in your party.

Go where ever you can find a Ditto and battle it. Let it transform into your Pokemon with the 21 Special stat. After it transforms, defeat it. It is safe to switch out to a different Pokemon now to beat it, if desired.

Fly to Lavender Town and walk off the west end of town. Mew should appear...

2. Walk past Nugget Bridge and left at the end of it. See that grassy bridge right there? Well, go in there, but DO NOT VERSUS THE TRAINER. Now, walk around in the grass until you find an Abra. Catch it when you see it, a simple PokeBall without dealing damage should do the trick. SAVE THE GAME. Now, if the Abra was sent to the PC, store 2 of your Pokemon and withdraw Abra. Why deposite 2 Pokemon? Because you need an extra space in your party to staore Mew. With Abra and 4 other Pokemon in your party, Save the game again, if you want. Head up Nugget Bridge, then swing to the right. You will see a Trainer facing the right, he's one of the first Trainers that will enter your screen. Well, you're going to have to battle him. After doing so, walk into Cerulean City again, then walk back out onto Nugget bridge and head a left where the Trainer in the grass is (I'll explain later why you need to do this). What you'll want to do now is position yourself to be directly above the Trainer, but have him still be one step-square below the screen's view. To give you a feeling of what I mean, position yourself on the left side on the grassy bridge, just down far enough so that you can see 4 grass squares in a square formation below you. Got that? Now SAVE. When you're ready, step down one square and press Start really fast. If done correctly, your manu should pop up, and the Trainer should be to the left of the menu. Now go to your Abra and tell it to Teleport to the Cerulean Pokemon Center. Once you arrive, your A, B, and Start button will not function.


Now, you can battle one of two Trainers now.


You can either battle the first Trainer in Misty's Gym (This way is easier) or you can battle the Trainer on the Route to the right of Nugget Bridge with the Slowpoke. Let's go with the Gym Trainer now, though.

When you walk into the Gym, walk in front of the swimming Trainer and defeat him. Now walk out side of the Gym. Save the game, buy PokeBalls, heal your Pokemon, whatever you need. When you're ready, walk up Nugget Bridge. While walking, your menu should suddenly pop up. Simply press B, and... MEW!

3. You can do the above obtainable, but instead of using Teleport, you can use Fly, if you have it.

4. Find a Trainer, any Trainer, and battle him/her. After the battle, fight a wild Pokemon that might have a spacial stat of 21 or 277. If that Pokemon does have a special stat of 21 or 277, then you should be able to find Mew by either going into the route where the Trainer was that you battled before the Pokemon battle or be able to walk off the west end of Lavender and be able to encounter Mew.

5. Through a GameShark.

6. Through encountering Error Pokemon on the east shore of Cinnabar Island or Seafoam Islands. To encounter Mew as an Error Pokemon, try starting the game with your name as "Xavier" (without the quotes), you may be able to find high level Mews, but I cannot promise this.

Level 'em up for a start. Evolve the 3 starters and you'll be unstoppable! Also get a ground type because poisan types are weak to ground and their moves don't work on them 8) :p

He is a poison type leader, the following types would help: Fire, Poison, The type super-effective against him would be Psychic... Grass and Water are weak to him

I had my full team with the two highest being level 37, and the rest being about 33ish. I would recommend fighting more trainers, and potentially using Jolteon (eevee found in Cerulean Mansion I think) and switching it out for pikachu.

On the renaming, potentially nickname them the first half of their name. Example: Pikachu=Pika Ivysaur=Ivy. Or just whatever you want

You need to level them up some more. I beat him easily with level 35 Pokemon
