In Gold and Silver, Pokemon evolve through different ways other than trade, level up, or use of a stone. Now there is newer ways, some just a tiny tweak of past methods. Below is a list of every Pokemon that now evolves in a different way and what that method is. These evolution methods for these Pokemon remain the same throughout the generations.

Color Generation Pokemon evolutions are not listed here even though they do make in-game appearances in G/S. This is because the evolution method has not changed for them. If you would like to view those methods, please click here
