Template:ItemTable Missing No. is a passive collectible.

Effects

  • Randomizes passive items and stats on pickup and at the start of every floor.
    • Does not affect trinkets, cards, pills, or active items.
    • Does not remove transformations.
    • Chance of crashing game upon pickup.



Strategy

  • There is no real strategy to Missing No. as it randomizes all the player's items. The benefit of the randomization can be added by collecting more items to increase the chance of a good item synergy.
  • However, this item can be used to gain more health if desperately needed, as the randomization does often include items that grant you various types of hearts.

Trivia

  • This item is a reference to the infamous Missing No. glitch occuring in the first Pokémon games. The glitch would often corrupt save files, and therefore randomize various parts of the game. Isaac's appearance when affected by Missing No. is based on this glitch which could cause the player's sprite to become scrambled.
  • The item also resembles the painting "Composition with Red, Yellow, and Blue" by Dutch painter Piet Mondrian.
  • The background color for the Missing No. achievement has the same color as all the challenge unlocks. This implies that Missing No. was originally intended to be unlocked via a challenge. (Or, perhaps, it was intended to be looked at as an error.)
