Monster Collection
One of the longest running Pokémon figure series is the Monster Collection by Takara Tomy. It is also know as Mone-Colle. They are standard PVC and basicly has every Pokémon made in them, except for some of the latest generation which is still in production. It's first release was in 1998. Due to it's popularity it has many spin-off series. Two of them are pretty new and are called Supersize Monster Collection and Hypersize Monster Collection.
Shaymin
One of the first non-TFG figures I got were these cute adorable Shaymins. One in it's Sky Forme and of course a normal Land Forme. These are one from the main Monster Collection series. They are about 5 to 7 cm, depending on the figure.
