(in Repentance)

TMTRAINER is an unlockable passive item added in The Binding of Isaac: Repentance.

Effects[ | ]

  • When picked up, all future items become "Glitched", causing them to become random combinations of 2-3 effects based on other items as well as effects that are not normally controlled by the player, such as enemy spawning and other behind-the-scenes effects.
  • "Glitched" items can be passive or active and are completely randomly generated with practically infinite possibilities. There is a 75% chance that the item will be passive.
  • Random effects combine effects that exist on other items, and assign them to a random event (e.g. on enemy death, on room clear, on damage taken etc.).
    • These effects may also be derived from installed modded items.
  • Glitched items sold for money cost a random amount of pennies up to 99 pennies.

Notes[ | ]

  • Once Corrupted Data Corrupted Data is unlocked, the TMTRAINER effect may be randomly applied to items found in Secret RoomSecret Rooms and I AM ERRORI AM ERROR rooms.
  • Items affected by TMTRAINER may take the effect of rerolling all of your items. This includes TMTRAINER itself, meaning any future items you encounter will not be under its effect, nor will the items obtained by rerolling due to the glitched item.
  • All glitched items appear as Collectible Mega Blast iconMega Blast in Isaac's Last Will or the In-game Pause Menu.
  • If an item held by Isaac is rerolled into TMTRAINER (Either by Collectible D4 iconD4 or a 1-pip Dice RoomDice Room), all items after it will be rerolled into glitched items.
  • A majority of the random item effects include farts, including active items.
  • Due to the sheer randomness of glitched items, some may cause the game to either crash or lag to the point of unplayability.
    • However, some may spawn entities that are normally only accessible using the Debug Console, including the Challenge Trophy that spawns at the end of Challenges and the Big Chest that spawns after most major bosses. Touching either of these on a floor that would not normally spawn them will instantly end the run and send the player back to the title screen (unless a challenge is currently being played, in which case the player will receive unlocks as if they had completed the challenge normally). Touching a Big Chest on any floor that can spawn them will NOT give the player the respective completion marks but will still end the run (unless Isaac has either Collectible The Polaroid iconThe Polaroid or Collectible The Negative iconThe Negative and is on either CathedralCathedral or SheolSheol, respectively.)

Trivia[ | ]

  • The name and description of the item comes from the result of glitches in Pokémon Red and Blue. Certain glitch moves in that game can have names so long they run into the memory, corrupting it and causing glitchy effects, like the opponent's name becoming "TMTRAINER". A certain other glitch (commonly referred to as the ZZAZZ glitch) replaces the letters in the player's name with capital Zs except for every third letter.
    • The pickup quote for this item is defined as "Isaac and his mother lived alone in a small house on a hill", but in game it's shown with the pattern of Zs overlaid on top.
      • When viewed in the collection grid, the pickup quote is unobscured, but it's so long it goes off of the screen.
    • The music fading out and status effects being applied to enemies upon acquiring the item is another direct reference to the effects of TMTRAINER in Pokémon Red and Blue, which fades the music out upon use until another song is triggered to play (assuming the game survives the effects), as well as applying burn and frozen statuses to enemy pokémon.
  • The sprite for TMTRAINER itself is a heavily glitched version of Isaac's face, affected similarly to the face of Character Tainted Eden iconTainted Eden in menus.
    • For the TMTRAINER sprite in particular is a reference to how sprites corrupt in Pokémon Red and Blue, especially after encountering glitch Pokémon, by segmenting into strips, then rearranged, usually flipped around.
  • The effect of the item is similar to a "Randomizer" for other games.
    • The item's effect is a reference to an old randomizer mod that came out before Afterbirth+.[1]
  • This item is used in DELETE THIS (challenge #45).
    • DELETE THIS will always be unlocked before TMTRAINER on any given file. This item, Collectible The Small Rock iconThe Small Rock, Collectible Dirty Mind iconDirty Mind, and Collectible Spirit Sword iconSpirit Sword are the only items that appear in challenges before they are unlocked. Small Rock and TMTRAINER are also notable for not being unlocked by beating the challenge they appear in.
  • Collectible MEAT! iconMEAT!, Collectible YO LISTEN! iconYO LISTEN!, G FUEL!, Collectible PHD iconPHD, Collectible BBF iconBBF, Collectible BFFS! iconBFFS! and Collectible TMTRAINER iconTMTRAINER are the only ALL CAPS items in the game.
  • Most glitched item sprites are shown as Collectible Mega Blast iconMega Blast in Isaac's last will. Very rarely one will show a glitchy icon.
  • Sounds when picking up glitched items are often changed.
