If you mean in the wild thats R/S/E version of MissingNo and is dangerous to catch
Yes. Wild is something you don't want to mess with. If you encounter it, turn off the game immediatlely. If you don't, it will empty your bag. You can't escape either because it automatically saves after the battle.
Better yet, just don't use the code at all.
