In Pokémon Red and Blue, a wild "h POKé" appears if Method #3 of the Mew Glitch is used with a special stat of 195. h POKé is relatively safe (as it is a hybrid of Gengar) glitch Pokémon to use, but it can be difficult to catch and train because normally when h POKé is caught, its Pokédex data (which consists of random sounds and visual glitches) will lock up the game. The frozen Pokédex data can be avoided if the trainer catching h POKé has a Gengar registered in their Pokédex as "owned". A Red/Blue player can also have a Z4 (h POKé's Yellow version equivalent) traded from Yellow. h POKé's cry is long, glitched, and different every time its stats are checked, depending on the last cry heard. On rare occasions, h POKé's cry may lock up the game.
At 6,099 lbs, h POKÈ can be considered as the heaviest glitch Pokémon which can be obtained without the use of a cheating device.
