- Because Pokémon Brown is a Red hack, all Pokémon with index numbers 0 to 199 can be caught at level 1 using the Mew glitch.
- By extension, this means that Pokémon which evolve using items can also be obtained at level 1.
- Thanks to in-game trades, it is also possible to trade a level 1 Gligar for a level 1 Eevee that will evolve into a Leafeon, and a level 1 Rhyhorn for a level 1 Crobat.
