The Master Ball (Japanese: マスターボール Master Ball) is a variety of Poké Ball introduced in Generation I, and arguably the rarest of all Poké Ball variants. It is unique in the aspect that it is guaranteed to catch any wild Pokémon that it is thrown at (with the exception of the ghost Marowak and Kyurem while it is under Ghetsis's control). It shares this attribute with the Park and Dream Ball used within Pal Park and the Entralink, respectively. However, unlike these Poké Balls, the Master Ball can be obtained and used outside of these specific areas.
The Master Ball, like all Poké Balls, is spherical in shape. The top and bottom halves are divided by a horizontal black band, on which is the button found on all Poké Balls. The top half of the Master Ball is purple, with a white letter "M" on the front, with a pink circle on either side.
Master Balls are developed by Silph Co.
In the games
The Master Ball has been present in every main series Pokémon game. Usually, only one Master Ball is available to the player per saved game, although from Generation II onwards, additional Master Balls can be won from luck-based events such as Lucky Channel drawings, Pokémon Lottery Corner drawings, and Raffle Shops.

In the spin-off games
In the two Pokémon Pinball titles, the Poké Ball that serves as the pinball is capable of being upgraded to a Great Ball, an Ultra Ball and a Master Ball. However, this serves solely as a score multiplier, as catching a Pokémon is always guaranteed, even with a regular Poké Ball.
In Super Smash Bros. Brawl, the Poké Ball trophy mentions the Master Ball, identifying it as the strongest variety of Poké Ball.
NA: These valuable, powerful balls can capture any wild Pokémon. In Smash Bros., hard-to-find Pokémon often pop out of them. You can easily identify a Master Ball by the distinct purple appearance and large M on the top. A Pokémon within a Master Ball may turn the tide of battle.
PAL: A rare type of Poké Ball that never fails to catch a Pokémon. Throw one in this game, and the Mythical or Legendary Pokémon inside will come to your aid. Master Balls are easy to identify due to their purple colour and the large M on them. Use one to quickly turn the tide of any battle!
In the anime
In the main series
In Beauty and the Beach and A Hot Water Battle, Misty has a beach ball that was decorated to look like a Master Ball. In The Song of Jigglypuff, a picture of a Master Ball appeared on a billboard on a building.
In Whiscash and Ash, the fisherman Sullivan attempted to use a Master Ball in a last-ditch attempt to catch Nero, an oversized wild Whiscash that had long eluded him. However, Nero swallowed the Master Ball and disappeared back into the water, not being caught. At the end of the episode, Nero was seen playing with the Master Ball on its tongue.
In Pokémon Origins
The Master Ball never made an actual appearance in Pokémon Origins, only appearing in Silph Co. president's secretary's demonstration in File 3 - Giovanni. She mentioned that the Master Ball was still in development, and only existed as a prototype. She also told that it was why Team Rocket had taken over their office building; they intended to accelerate the development of the Master Ball and then steal it when it would be completed, making sure they would be the only ones possessing it. After Team Rocket was driven out of the building by Red, it was mentioned that the development of the Master Ball was put on hold for a while.
