Legendary Pokemon used to be good when there wasn't very many of them, like 5 or 6 per region or something. Not too many but enough to keep the fans of legendary Pokemon happy. Then we get the Hoenn, Sinnoh and Unova regions where we get double figures of legendary Pokemon, some of which are instantly forgettable, whilst others were made so ridiculously powerful and had such insane background stories it became laughable. I mean, we get a Pokemon that is basically God and supposed to have created the entire Pokemon world and we get a Pokemon that controls time and a Pokemon that controls space, excessive to say the least. Can you imagine a mere mortal owning a Pokemon with that sort of insane power?
