Q ◣
Q, commonly known as Q Glitch, is a Glitch Pokémon in Pokémon Yellow.
In Pokémon Yellow
Obtaining Q
There are only two ways to obtain a Q; by evolving a 44Hy or trading a Charizard 'M from the Red/Blue versions. It is easier to just evolve a 44Hy since Charizard 'M is hard to obtain. Q cannot be seen in the Menu or caught by directly using the Mew Glitch. Because of this, Q is one of the few non-Gameshark* Glitch Pokémon that cannot be caught by directly using the Mew glitch.
Stats
Q will have the nickname "TM55" when it has evolved from 44Hy. When viewing its stats, it will have the number #121 and its types are Water/Psychic.
Moves
Q's moves are Confusion, Disable, and Headbutt. At Lv. 9, it will learn a glitch move. Q sometimes will learn "trainer," a glitch that freezes the game. Q will learn Mega punch at level 12, Skull Bash at level 23, TM09 at level 29, TM50 at level 32, Pound at level 45, Tackle at level 61, and Ice Beam at level 62 (note: "TM" moves are not actually TMs, they are glitch moves).
In the party
Whenever Q is the first Pokémon in the party, all of the Pokémon below it will be invisible. Your party will now then be unable to heal at any Pokémon Center. The only way to heal them is to use items such as Revive. If Q is moved to the bottom of your party, all other Pokémon will once again be able to be healed at a Pokémon Center, but once Q faints, it can only be healed with a revive or similar item.
If Pikachu is below Q as well, he will vanish (the one seen following the player). Place Q as last in the party. All the Pokémon above will be visible again.
Evolution
At times, Q may unexpectedly evolve into Kangaskhan four times in a row, then suddenly freeze the game. Q has been also known to turn into Missingno. without evolving. It will then have Type 1 as Normal and Type 2 as glitch.
Duplication trick
Due to Q's unusual behavior, it and its Red/Blue equivalent Charizard 'M are the only Pokémon that enable a player to a unique trick, often called the "Q trick"[1]. It involves depositing Q and other Pokémon into Bill's PC, and then when they are retrieved, the Pokémon's attacks and stats will become mixed up.
In Pokémon Gold
When viewing Q in Pokémon Gold, it will appear as ????? as the number #255.
Notes
*There are other Glitch Pokémon that can be caught with Gameshark, a cheating device. "Non-Gameshark" implies a Pokémon which does not require Gameshark to find it.
