Pokémon Decay

Pokémon Decay is supposed to be a best of the first four generations.

It's intended to give the player as much nostalgia as possible by referring to the storylines of the old games.

Due to natural disasters the four regions Kanto, Johto, Hoenn and Sinnoh collided and became one big Region, the Talem Region.

The player wakes up and can't remember what happened. He has to find out what caused those natural disasters.

The flow of the game is similar to the original Pokémon Games:

The player has to defeat 8 Gym Leaders and the Elite Four while facing nearly all the well-known characters and evil teams of the first generations.

The Talem Region is inhabited by Pokémon from the first four generations.

Later Evolutions of those Pokémon are also included.

For self-preservation-reasons they had to adjust themself to the new environment.

That's why many of them had to change their typing.

Those Pokémon are known as Delta Species.

In total there are 131 Delta Species and 40 Evolutions and Pre-Evolutions of already existing Pokémon.
