I don't really like Chespin :-(. Yeah, since the Y is blue, then you should go for Blue. I take it you like blue things, then? Water types, and blue-themed games... interesting...
At least I have a friend now. I'm no longer lonely.
Sorry, but Fire/Fighting line is dead. In fact, I have only used a fire type once. Charmander. Jesus, it was a long time ago. Ever since then, I've had 2 Grass starters, and 2 Water Starters. Treeko and Snivy, and Totodile and Piplup. They will always be my favourites. Dragon Legendaries are awesome, I think they will pretty much always have a Dragon-type in the game, main legendary or not. People get bored of Dragons, but in every single generation, a Psychic type and Flying type Legend has been introduced. Come on, that's getting old.
Really? Well, ur... I dunno what to say there. Y'sure? I think they are perfectly Draconic. However, Dialga, Palkia and Giratina are a little... weird. Also, could you please explain to me Dialga's typing. I get Palkia's, the Pearl, Pearls are found in water... yeah. Giratina's... it's found in a reverse world, it's basically an undead dragon, that makes sense too. But Dialga's? Help Me.
