'''Brock Throughthrough Wallswalls''' ('''path manipulation walk through walls''') is a [[walk through walls]] glitch in {{RGBY}}. It is popular in speedruns of Pokémon Red and Blue. It is possible to perform this glitch very early in the games (except in {{Y}}, as the Youngster cannot be skipped in this version).
 
There are various ways to set up this glitch, but it is ultimately triggered by talking to the Pewter City Youngster from the right instead of the left, which was not intended to be possible.

==Variants==
===Brock Fly===
In order to execute Brock Throughthrough Wallswalls, the invalid path needs to be long enough to overwrite at least the entire RAM region between $CCD3 and $CD3B. Most addresses in this region are temporary variables anyway; however, this region includes $CD2D (wEngagedTrainerClass) and $CD2E (wEngagedTrainerSet), which determines the species and level of the Pokémon encountered with the [[trainer escape glitch]] (normally the Special stat and Attack modifier of the last enemy Pokémon). Therefore, by doing a trainer escape, and performing this glitch before going back to the route, the player can set up a "Special stat encounter" without needing to fight a Pokémon with the appropriate Special stat and Attack modifier. Notably, this allows encountering a Pokémon whose level is not in the 1~13 range (the valid range for the Attack modifier byte).
 
This variant is named "Brock Fly" because "Trainer Fly" is a more commonly known name for the trainer escape glitch, but of course other escape methods (Teleport, Dig/Escape Rope, death-warp) can also be used.

===Brock Throughthrough Wallswalls from a wall===
It is possible to trigger this glitch from the ''top'' of the Youngster, as long as the player can reach there using another glitch (e.g. [[Rival's effect]]). The principle of setup is similar, but instead of "0x10 0x24", the player needs to set up "0x0F 0x23" at an appropriate address, since that is the coordinates of the tile above the Youngster.

==Entering the Pokémon League with no badges or wrong warps==

===Optional steps===
To make the Elite Four challenge less difficult, more than one Brock Throughthrough Wallswalls iteration can be used if an Escape Rope (from Pewter City Poké Mart) or Pokémon with Teleport (i.e. Abra) is prepared and the last location that the player healed at was Viridian City or Pewter City (or Pallet Town?). This can be done to acquire TMs (such as TM26 Earthquake from Silph Co. 10F).
 
Trainers can be grinded against to afford items such as X Attack and X Accuracy, and the player can set up or heal their Pokémon if a Poison-type Pokémon is sent out against Lance's Dragonair, which can only use Agility against those Pokémon and with infinite PP.

==Notes==
