Colosseum

[SaddQ]

Which gen 1-3 Pokemon do not appear at all in Colosseum or XD unless traded in from the GBA games? Are there any at all?

Furkle and Nesblob don't appear at all unless you enter the Konami code on the litterbox screen.

There is not a list that I'm aware of, but there are lists of those that -do- appear.
