Well i hope in Diamond and peral you have an option of chosing a pokemon to follow you around. Not a big pokemon. A pokemon the size of Pikachu, Vulpix, Eevee, Torchic, Mudkip, etc. Also i hope the legendarys are much better than Kyroge and Groudon. Even though in Emreald you can catch both. Rukario Is prob a water or fighting type. I say water because its the title. ' Mew and the wave guiding hero - Rukario' But figthing cause of the size of the fists on the pokemon.
