Fire Red - Flareon
Leaf Green - Jolteon
Diamond - Espeon
Platinum - Glaceon
I then bred Espeon with a Vaporeon I caught as an Eevee, producing two eevees which eventually evolved into Leafon and Glaceon, I then migrated Jolteon and Flareon from Kanto.
In Platinum I plan to breed Glaceon with another Espeon to produce 3 Eevees which I'll evolve into Jolteon, Vaporeon, and Flareon, then I'll catch another Eevee and evolve it into Umbreon.
