Pokédex entries
| RedBlue | Almost invisible, this gaseous POKEMON cloaks the target and puts it to sleep without notice. |
|---|---|
| Yellow | Said to appear in decrepit, deserted buildings. It has no real shape as it appears to be made out of gas. |
| Stadium | Made of a thin, gas-like substance that induces fainting if you get enshrouded in it. Will not appear if it is very windy. |
| GoldStadium 2 | With its gas-like body, it can sneak into any place it desires. However, it can be blown away by the wind. |
| Silver | Its thin body is made of gas. It can envelop an opponent of any size and cause suffocation. |
