>>12801166Pokémon that are more "beastly" generally get cries like that. Like dragons or some birds like Pidgeot.
Reshiram and Zekrom are recent pokémon, but they also have awesome dragon cries in the anime.
Machine-like pokes tend to get cool cries too, like the Regis and Magnemite line.
Unfortunately, a fucking ton of mons just sound like people trying too hard to sound like pokémon. Which is a shame because most game cries are awesome.
(I only know recent anime voices in japanese, though, so not sure what they are like in the US dub)
