Arceus
i would have to say Dark Rai

It depends on the games you got it in and the game you transfer it to, but most items will work in most games.
Arceus
Most diamonds are used in industry and not in jewelry. Their hardness makes diamond useful as a cutting tool.
Dialga!!!
Most game stores.
Well the legendary Pokemon is Dialga but most of the other Pokemon are the same.
The best Pokemon on Pokemon diamond is obviously a Bidoof...Joke :)No this is entirley an opinion based question but the best aka most powerful,and most defensive is Diagla
Arceus the Alpha Omega God Pokemon
