Pokédex entries
| Red Blue | Because it stores several kinds of toxic gases in its body, it is prone to exploding without warning. |
|---|---|
| Yellow | In hot places, its internal gases could expand and explode without any warning. Be very careful! |
| Gold | Its thin, filmy body is filled with gases that cause constant sniffles, coughs and teary eyes. |
| Silver | The poisonous gases it contains are a little bit lighter than air, keeping it slightly airborne. |
| Crystal | If one gets close enough to it when it expels poisonous gas, the gas swirling inside it can be seen. |
| Ruby | If KOFFING becomes agitated, it raises the toxicity of its internal gases and jets them out from all over its body. This POKéMON may also overinflate its round body, then explode. |
| Sapphire | KOFFING embodies toxic substances. It mixes the toxins with raw garbage to set off a chemical reaction that results in a terribly powerful poison gas. The higher the temperature, the more gas is concocted by this POKéMON. |
| FireRed | Its thin, balloon-like body is inflated by horribly toxic gases. It reeks when it is nearby. |
| LeafGreen | Because it stores several kinds of toxic gases in its body, it is prone to exploding without warning. |
| Emerald | Getting up close to a KOFFING will give you a chance to observe, through its thin skin, the toxic gases swirling inside. It blows up at the slightest stimulation. |
| Diamond Pearl Platinum | Lighter-than-air gases in its body keep it aloft. The gases not only smell, they are also explosive. |
| HeartGold | Its thin, filmy body is filled with gases that cause constant sniffles, coughs and teary eyes. |
| SoulSilver | The poisonous gases it contains are a little bit lighter than air, keeping it slightly airborne. |
| Black White | Lighter-than-air gases in its body keep it aloft. The gases not only smell, they are also explosive. |
| Black 2 White 2 | Toxic gas is held within its thin, balloon-shaped body, so it can cause massive explosions. |
| X | Its thin, balloon-like body is inflated by horribly toxic gases. It reeks when it is nearby. |
| Y | Lighter-than-air gases in its body keep it aloft. The gases not only smell, they are also explosive. |
| Omega Ruby | If Koffing becomes agitated, it raises the toxicity of its internal gases and jets them out from all over its body. This Pokémon may also overinflate its round body, then explode. |
| Alpha Sapphire | Koffing embodies toxic substances. It mixes the toxins with raw garbage to set off a chemical reaction that results in a terribly powerful poison gas. The higher the temperature, the more gas is concocted by this Pokémon. |
