Answer 2

Yeah I've completed the National Pokédex in Diamond and all that happens is when you talk to Dawn/Lucas they say Congratulations for completing the Pokédex!! and when you talk to Professor Oak he says Thank you sencirely from the bottom of my heart Etc. I thought you'd at least get given a Cool Item but no. Retarded but anyway, It was fun.
