Miror B

You can find Miror B early in the game. The first time you encounter him, he will ask you to join his group. If you say yes, he will think that you are lying. Say no, and he will get mad. Either way, you will have to battle him. He has a Shadow Nosepass. The second time you encounter him, he will be on an island. When you talk to him, he will battle you again. This time he has a Shadow Dragonite, and also the Shadow Nosepass if you did not catch it earlier.

Master Ball

To get the Master Ball, see Professor Krane at the Pokemon HQ lab. He is in a room on the first floor. Talk to him and he will open up a passage in the floor. There is a chest in the room. Open it to find a Master Ball. You must have been to Citadark Isle at least once to get the Master Ball. It is best used on Lugia.

Fourth generation Pokemon

There are two new Pokemon in this game from the fourth generation. They are Munchlax and Bonsly.

Gateon Port items

When questioned by Acri at Gateon Port, she will give you one of four different items depending on your answers. To get an Amulet Coin, answer ‘Yes’ to all her questions. To get a White Herb, answer ‘Yes’ to two of her questions. To get a Mental Herb, answer ‘Yes’ to one of her questions. To get a Quick Claw, answer ‘No’ to all her questions.

Elekid

You must do something for the news crew to get Elekid. They will ask you to check with someone in the outskirts. His name Hordel and he is from Cipher. He will give you a Togepi at level 25 and ask you to purify it for him. Once this is done, you can keep it or take it back to him. He will trade you an Elekid at level 20.

Johto starters

It is possible to get all three Johto starters. Successfully complete Mt. Battle in Story mode to get one Johto Pokemon with their elemental hyper beam. Totodile will have Hydro Cannon. Cyndaquil will have Blast Burn. Chikorita will have Frenzy Plant. You can get all three starters by completing Mt. Battle a total of three times.

Lugia

Lugia can be caught at Nickledark Island. He comes out at level 50 after you defeat Cipher Boss Deathgold. To purify Lugia, get full tempo in all nine chambers. Then, place Lugia in one of the sets and it will be purified.

To get an opportunity at snagging Lugia in the demo version, you must first snag the first 60. Then, go to the mountain with a Groundon statue and Lugia will fly there. You will them battle him; he is at level 50.

Snag two Shadow Pokemon at once

Occasionally some trainers will have two Shadow Pokemon to snag; be careful when this happens.

Snag six Shadow Pokemon at once

The final Boss has six Pokemon to be snagged: Rhydon (level 46), Zapdos (level 50), Tauros (level 46), Exeggutor (level 46), Articuno (level 50), and Moltres (level 50). Go to the Outskirts and buy twenty of every kind of Pokeball. You should also use your Shadow Pokemon against his and they will not do very much to each other. Additionally, in the final battle with Greevil, if one or more of the Shadow Pokemon faint, do not reset. Just win and fight him again. He will have the one(s) that you missed, and the rest will be normal. Also, if you already have Shadow Lugia, you will only battle Greevil.

Classic battle

At the Outpost stand, talk to the man with the pink hair. As you leave the stand he will challenge you to a battle. Accept and you will battle Rider Willie, the first trainer from Pokemon Coliseum. Also, the background music will be that from the Pokemon Coliseum battle. You can challenge him whenever you desire.

Easy purification

To get your Pokemon purified easily, keep the Pokemon with you for at least ten minutes, then put them in the purification chamber. They will purify about 25% faster than normal.

Agate Village

You can return to Agate Village. The only difference is that there are different people and it is five years later.

They are Shadow Crush, Shadow Attack, Shadow Wave, Shadow Rave (same as Shadow Wave except stronger), Shadow Weather, Shadow Down, Shadow Half, Shadow Mist, Shadow Remove, Shadow Hold, Shadow Panic, Shadow Storm, Shadow Break, Shadow End, Shadow Chill, Shadow Bolt, Shadow Fire, and Shadow Blast
