Instructional walkthrough

Ruins of Alph (Part 1)

Despite that the Ruins of Alph is accessible after completing Goldenrod City's gym, police officers will be blocking every ruin until the player has completed the Johto Elite Four. Once that has been achieved, the police officers will trust the player with a mission; find the scientist that have gone missing inside the ruins.

The Scientist, called Alexander will be found in the Puzzle 2 building, and thus is will be necessary to bring a Spinarak. After finding him, he will explain that he's looking for an important item, and wants the player to find it for him.

After speaking to Scientist Alexander, it will now be possible to examine the Pokéballs at the bottom of each Puzzle room. The item he is looking for is in the Puzzle 4 building, and thus it will be necessary to bring a Rattata and reach the building through Union Cave. At its bottom, the G.S Ball, the item he is looking for, will be the northeast item.

After bringing the G.S Ball back to him, he will reward the player with one of four different Fossils, namely the Helix Fossil, the Dome Fossil, the Claw Fossil and the Root Fossil. The Hoenn fossils being rarer, it is recommended to pick between the latter two. He will then ask to return later when he has fixed the G.S Ball, putting an end to the first part of the Celebi quest.

The seen data of this Pokémon can be obtained by a battle against their NPC. They appear as Pokémon sprited NPC's and are one time battles. Means, they won't respawn, no matter if the fight is won or lost. The seen data is saved anyway.

While the three legendary birds don't need specific requirements, besides having a Pokémon knowing HM03-Surf, Mewtwo can only be reached after doing the eponymous quest. Articuno is located at Seafoam B4F, Zapdos at Power Plant, Moltres at Victory Road and Mewtwo in Cerulean Cave B1F in Kanto.

Suicune, Raikou, Entei and Ho-Oh's seen data

Travel to Ecruteak City and talk to Scientist Ray at the Bell Tower Entrance. When you are Johto champ, he will ask you if you could help him and his researching team since you have the Pokédex. Now head to Scientist Ray inside of the building and interact with him. He will ask if you return to him when you have to seen data of all three Legendary Dog's. Fight your way through the Bell Tower Basement and interact with the three Legenday Dog's, which will flee after you did.

Now you can obtain their seen data by batteling them. Entei is located at Johto Safari Mountain Zone. You need a Pokémon knowing TM114 Rock Smash or a Pick Axe in order to destroy some rocks in order to reach Entei. Suicune is located at Tohjo Falls and you need a Pokémon knowing HM07 Waterfall and a Pokémon knowing HM03 Surf or a Surf Mount. Reikou is located at Mt. Silver 3F.

Once you fought them and got their seen data, head back to the Scientist and report your findings. Now you can walk to the Bell Tower Rooftop and get Ho-Oh's seen data.

Lugia's seen data

The seen data of Lugia can only be obtained by defeating Thor and requires 6 level 100 Pokémon in your team. You also need a Pokémon knowing HM03 Surf or a surf Mount to reach him. Thor is located in Whirl Islands B4F and can use one of three teams which will be randomly set.

Ilex and Chronos Forest

Ilex Forest

After retrieving the G.S Ball from Scientist Alexander in Ruins of Alph, the next destination for the quest will be in Ilex Forest. The next thing to do is to examine the shrine in the middle of the path through the forest. If it is examined between 00:00 and 01:00 in-game time, the G.S Ball will react and the player will be teleported to the Chronos Forest, where he or she will be put to a few trials before being able to capture Celebi.

Before entering the Chronos Forest, make sure to prepare a Synchronize Pokémon, a Pokémon to weaken Celebi, a sufficient amount of Pokeballs, as well as a Surf method; many bodies of water are necessary to cross in order to reach Celebi.

Chronos Forest Area 1

Upon entering Chronos Forest, Time Guardian Charles will present the player the first trial before getting Celebi. The trial consists of finding a total of 10 Time Shards, all of which are hidden items spread throughout Chronos Forest Area 1.

The location of each Time Shard is shown on the area map below.

Once all 10 Time Shards have been obtained, it will be necessary to hand them to Time Guardian Charles, after what the two Time Guardians blocking the way to the next area will disappear. Charles will also notify the player of how many Time Shards he or she has obtained by speaking to him.

Chronos Forest Area 2

The second trial will be explained by Time Guardian Topan. The goal is simple: reach the other end without being seen by the many Time Guardians in the way. If they see the player, they will kick him or her back to the end of Chronos Forest Area 1, as such there is no significant penalty by failing the trial.

Lake of Shine

Celebi will be located in the middle of the last area, the Lake of Shine. While there are no particular trial here, there are a couple short mazes to cross in order to reach Celebi.

Once in front of Celebi, talking to him will automatically initiate a battle in which he can be captured. The Celebi will be level 30 and know the moves Ancient Power, Magical Leaf, Safeguard and Recover.
