Raquaza
Catch raquaza
Raquaza isn't in either Pokemon Diamond or Pearl.
raquaza is a master legendary Pokemon in emerald ruby and Sapphire. his is most likely to be the best Pokemon in the series (Case in point)
You catch Raquaza in the Sky Pillar on the island near Pacifilog City.
trade it from emerald or get a gameshark and get some code to get a raquaza
in ruby and Sapphire raquaza can be found at the sky pillar in the lower watery routes on the right of a town on water if you search carefully, but you probably can't get to it until after the Elite 4. Raquaza should be on top level of the tower at level 70 so be prepared. (plus there should be some decent leveled Pokemon there as well.

The dungeon ends on level 25, but continues for 9 more stages in the Sky Tower Summit, so he's on level 31.
you have to first defeat raquaza hope it helped :D At level 36, if I remember, unless you choose to delay his evolution.
