What happens in the Pokemon games when you catch all possible Pokemon?

It's just bragging rights. I have all 493 of them. Nothing special happens. I'm waiting for next version come out, which are probably remakes of G/S.

Red and Blue DO NOT use the Game Boy Printer. Only Yellow, Gold, Silver and Crystal use it. I have it in my bedroom, the printer that is.
