what is this for

Hi I need some help. I used a cheat in pokemon diamond and I got this a Red chain. What is it for? ???

 

It's connected to the story event featuring D/P's legendary three pokemon

 

yeah but when I played pokemon pearl I saw how they use it to call Palkia but I didn´t get it. Why is diferent now. Can I sumon Dialga twice?

 

Nope; they can use it and you can get it afterwards but you can't use it to summon Dialga

 

oh is of no use after Dialga beaten. Ok thank you

 

basically it's supposed to be used to summon Dialga or/and Palkia but they awaken themselves so you don't actually need it, if you play through without cheats you don't get it because it was removed but if you cheat you can get it to show off

 

So it's just a dummied (removed from the game scenario sytem but not totally removed from the game's item inventory) item then?
