Let's discuss, /vp/. How many individuals are there for a Legendary Pokemon species? I'm not asking for an exact number; rather, I'm just asking which Legendary Pokemon do you believe that there exists more than one of?
Be wary of opinions, guys.
Giratina and the Sky Warrior proved that more than one Shaymin exists, but I don't think there are multiple Giratina/Palkia/Dialga/Arceus. In the movie, at one point, a Regigigas appeared to stop the ice wall from advancing, so I'm thinking that it couldn't have been a coincidence that Regigigas just happened to be in the area; there seem to be Regigigas placed everywhere.

So, discuss.
