The one aspect of Pokémon that will never die for me is the heart of the series--the games! This section displays my various Pokémon teams from the different games.
Kanto Generation
Johto Remakes
Hoenn Generation
Sinnoh Generation
Unova Generation
Above are my primary teams. I generally raise each new generation of Pokémon in the games they debut in, so that each game is a fresh adventure without re-raising Pokémon or trading them over from previous versions.
Below are the secondary teams, raised on games where no new Pokémon were introduced (with the exception that my original Silver battery died).
Kanto Remakes
Johto Generation
Pokémon Colosseum
Gale of Darkness
Gen 6+ Hypotheticals
By the way, I tend to train whichever Pokémon I like as the mood strikes; I don't make actual "battle teams" with type combination balance, I just group every six Pokémon together in the order they reach Level 100.
