3TrainerPoké

3TrainerPoké is a Glitch Pokémon that only appears in Pokémon Yellow by trading a 'M from Pokémon Red and Blue.

Appearance
3TrainerPoké appears as a skinny rectangular image, filled with scrambled bits of data as most glitch Pokémon are. It's colouring is both yellow, red and black.

Effects
3TrainerPoké's glitch effects are limited and generally do no severe damage.

While not doing any severe damage it still retains the effects of most Glitch Pokémon. One of them is rather common, when you catch 3TrainerPoké it will scramble your Hall of Fame, just like MissingNo..

Another glitch is the fact that it can evolve. At level 1 it can evolve into a Kangaskhan and at level 128 it will evolve into a Clefairy. This is difficult to do, however, because its stats and levels change at random.

Location
3TrainerPoké is only obtainable by trading a 'M from Pokémon Red and Blue. This is because the Special stat required for the Mew Glitch is 0, this can not be done because no Pokémon has a Special stat of 0.

Trivia

 * 3TrainerPoké is a Glitch Pokémon that does not share its Pokédex with another Pokémon.
