Special Event Pokemon

Appendix 04

Special Event Pokemon

Please note:  I have not actually tried these, I am simply reporting what has been officially released on the Japanese Sites about them.  Please understand that these events may not take place at the same time in every region -- for example the Japanese Region already has a lot of these Pokemon but most of the other regions do not.

Conventional wisdom dictates that we will eventually receive these, however the question is when.  IF you have one of these from a different event/source, DO try to trigger the event with it.  I was able to trigger the Celebi Event with the Celebi from Pokemon Colosseum.
 

- Arceus Event
If you obtained Arceus from the special event and you trade it to HeartGold, and then take him as your party lead to the Ruins of Alph you will open a new area and meet Cynthia, the former Sinnoh Champion!

Cynthia will explain to you that your Arceus has the special ability to create newborn Pokemon and then give you the choice of creating a Level 1 Dialga, Giratina, or Palkia.  What you choose is up to you, but all three of these are available in the other games for trade into this one, so really it depends on what game(s) you do not have, as obviously you should choose the one from the one you do not have, right?

- Celebi Event
If you obtain a Celebi from an event and trade it to HeartGold, you can place it in your lead party slot and visit its shrine in the Ilex Forest to trigger a time-travel event that will fill in some details about the game that you have no other way of obtaining.  I cannot go into any more detail on this without ruining this event for you.

- Pikachu Colored Pichu
I actually have this one from the event but have not used it yet...  If you trade the Pikachu Colored Pichu into your party and put it in the lead position (make sure you have an open party slot), and then visit Celebi's Shrine in the Ilex Forest, a Spiky-eared Pichu will join your party.

The Spiky-eared Pichu is a truly unique Pokemon that cannot be obtained any other way -- it has special moves that that evolutionary line normally cannot learn or obtain, it has a special held-item, and it is always female.

If you place the Spiky-eared Pichu in your lead party slot and take it to Professor Oak he will give you information about its unique origins.  He will also rate it untradeable -- but it is already untradeable so not showing it to him still will not allow you to trade it to a different game.
